Chocolate muffins that truly taste of chocolate and stay fresh for days are a rarity! This recipe delivers, thanks to some tidy tricks including hot milk to bloom the cocoa, and a little coffee to enhance the chocolate flavour (you won’t taste the coffee). Using brown sugar, oil, sour cream and less egg meanwhile is the secret to keeping the crumb ultra-moist and tender!

Chocolate muffins are not all created equal. I’m fussy about mine and make no apologies about it – there are a lot of calories in a muffin, so every one of them better be worth it! 😂 Here’s my laundry list of things a great chocolate muffin needs to have. It must:

  • Have a lovely crisp dome

  • Be tender and moist inside

  • Truly taste of chocolate

  • Be quick and easy to make (as muffins should be!)

  • Not include obscure or just plain weird ingredients

  • Stay fresh for 3 days

  • Be still good for even another 2 days after that!

While this list of chocolate muffin characteristics might sound obvious to you, finding a recipe that ticks all these boxes is much harder than you think! In fact, in my whole cooking life, I have never come across a keeper.

After (many!) years of attempts, I finally buckled down and committed myself to pursuing the ultimate chocolate muffin recipe, even if it killed me. In the end, it was a plethora of simple baking tricks that came together in creating what is my idea of the perfect chocolate muffin. I’m VERY happy with the end result and thrilled to share it!

Chocolate muffins are notorious for being dry because of the cocoa powder. But not these!

The simple baking tricks for the BEST Chocolate Muffins ever!

Here’s the complete list of the simple tricks that make all the difference in this recipe. An explanation of the why behind each of these is in the ingredients section below.

  1. 1 egg rather than the usual 2 eggs;

  2. Brown sugar instead of white sugar;

  3. Oil instead of butter;

  4. Sour cream instead of milk;

  5. Coffee to enhance chocolate flavour (optional);

  6. Dutch-process cocoa powder for more intense chocolate flavour (optional);

  7. Blooming the cocoa powder with hot milk;

  8. Thinner batter than the usual muffin batters; and

  9. Briefly bake on a high temperature then lower temperature to finish!

Ingredients in Chocolate Muffins

Here’s what you need to make these Chocolate Muffins. If you’re wondering – coffee? Did she make mistake? Read on below for why!!

Ingredients in Chocolate Muffins
  • Instant coffee powder or granules – This is an age-old baking trick used to enhance chocolate flavours because chocolate and coffee share similar taste characteristics. You can taste the coffee in the raw batter but once baked, you cannot taste it. Any instant coffee powder or granules works fine here, no need to use an expensive one!

  • Dutch process cocoa powder – This is a darker cocoa with a more intense chocolate flavour and colour than ordinary cocoa powder. It is slightly more expensive but yields a better result.

    Ordinary cocoa powder (unsweetened) will work just fine too. The colour of the muffins however will not be quite as deep and also it will taste slightly less chocolatey.

  • HOT milk – A trick used in my Chocolate Cake and Fudge Cake, hot liquid (usually water) mixed with cocoa powder makes it bloom! This brings out the flavour and makes the muffins taste more chocolatey.

  • Just 1 egg – Eggs are required to bind the crumb of cakes. But the problem is the whites tend to also dry baked goods out! So we use just 1 egg here. Compared to using 2 eggs, the extra moistness in the crumb is remarkable.

  • Oil – This is the fat used in the chocolate muffins instead of the usual butter. While I love the flavour butter brings to baked goods, it actually has a drying effect on the crumb compared to oil. My side by side tests confirmed this also for this muffin recipe. So, oil it is!

  • Brown sugar – While white sugar will make a slightly crisper dome, brown sugar retains moisture better which means the crumb is more moist (notice a trend we’re aiming for here??). It also adds a lovely caramel flavour to the crumb which compliments the chocolate flavour.

    As for making the dome crisp? I wasn’t willing to give that up! So I just blast the muffins at a slightly higher temperature for the first 5 minutes which helps give it a nice crispy dome. Now we get the best of both worlds!

  • Baking soda (bi-carb) – This makes the muffins rise slightly better than using baking powder, while preserving the intense dark chocolate colour of the crumb. Baking powder does also work perfectly fine (use 4 teaspoons) but the muffins rise slightly less and give a slightly paler crumb colour.

  • Vanilla – Just a touch, for flavour! Vanilla extract is fine to use here and is preferable to artificial vanilla flavouring. While real vanilla beans or vanilla bean paste has its place, I wouldn’t bother wasting them for this recipe.

  • Sour cream – Another baking trick! This lets us introduce wetness in the batter but keeps the batter a thicker consistency than using, say, more milk. We need a thicker batter for chocolate muffins than for, say, cupcakes, in order to achieve that lovely dome.

    Yogurt can also be used in place of sour cream.

  • Flour – Just plain / all-purpose flour. Self raising flour does work in place of using plain flour + baking soda as done here, but the muffins don’t rise quite as well. (I’d still use self raising flour if that’s all I had, though.)

  • Chocolate chips – I use dark chocolate chips (called semi-sweet chips in the US) but any type of chocolate chips will work just fine here. Or chopped chocolate! Just be sure to use baking chocolate (from the baking aisle), not eating chocolate. The latter is not made for cooking in the oven and funky things happen when you do!

  • Salt – Just a touch, it brings out the flavour in baked goods. Standard practice!

How to make Chocolate Muffins

Mix Dry , mix Wet, mix Dry into Wet. Bake. Do you really need me to give you any more detail? 😂

How to make Chocolate Muffins

The nice thing about these muffins is that you don’t need to be as careful about not over-mixing the batter (which causes a dry muffin) because this batter is not as thick as most muffin batters.

  1. Sift Dry ingredients – Sift flour, baking soda and salt into a large bowl. I don’t typically bother sifting flour for muffins, but seeing as we’re sifting cocoa anyway, I figure we may as well. Using the same sifter for the cocoa without cleaning the flour off is fine.

  2. Sift cocoa powder into a separate bowl.

  3. Bloom cocoa – Add the coffee powder and hot milk to the cocoa and give it a good whisk. This step of adding a hot liquid (usually boiling water) to cocoa powder makes the cocoa “bloom”, bringing out its flavour. It’s an age-old baking trick, one I use for things like Chocolate Cake and my Fudge Cake.

  4. Finish batter – Whisk in remaining wet ingredients (oil, sour cream, vanilla, egg, sugar – yes, sugar is classified as a “wet” ingredient in baking!) with the cocoa.

    Then pour this mixture into the flour and whisk. Initially, after the flour is incorporated, the batter will look a bit split (ie. it’ll have fine oil streaks). Whisk until it’s smooth and glossy, but stop once it is. Don’t keep mixing on blindly! This will overwork the gluten in the flour and make your muffins tough rather than pillowy soft! That said, this batter is thinner than most muffins batters so it’s more failsafe in this regard.

How to make Chocolate Muffins
  1. Stir in 1 cup of chocolate chips, reserving the rest for topping.

    Note: This batter is THINNER than typical muffin batters. This is one reason why these cupcakes have a much more tender and moist crumb than the usual chocolate muffins.

  2. Fill muffin cases. Use an ice cream scoop with a lever if you have one. This is a super-handy tool for muffins, cupcakes, fritters, even meatballs!

    Do not overfill! Fill the muffin cases up to 0.5cm / 0.2″ from rim of paper liner. Don’t fill any higher as the muffin will overflow when baked since this batter is quite thin. (see Note 5)

  3. Top with remaining chocolate chips. Just pile them in the middle, they will spread out as the muffin rises.

    Bake at HIGH temp 5 minutes – Bake for 5 minutes at 210°C / 410°F (190°C fan). Starting off at a slightly higher temperature gives the muffins a kick start on the rise (required for this thinner batter) and gives the muffins a crunchier top.

    Bake at LOW temp 20 minutes – Turn oven DOWN to 190°C / 375°C (170°C fan) then bake further 20 minutes. So, 25 minutes in total. This is longer than most muffins and it’s because the batter is thinner (contains more liquid).

    Notes on oven temperature: I know these oven temperatures are a bit unusual compared to the typical 180°C/350°F. I tried baking these at all sorts of temperatures and I honestly think the temperatures I’ve landed on yield the best result. The muffins have a nice rise, crisp dome, moist crumb inside, without overcooked edges.

    How to tell the muffins are baked: When a toothpick inserted into the middle muffins comes out clean, they’re done. Don’t confuse melted chocolate with raw batter! Probe in multiple places if you are unsure. (PS. The slightest faint smear of batter on the toothpick is ok because residual heat will take care of any remaining rawness).

  4. Cool for a few minutes in the muffin tin until you can handle them. The muffins are quite fragile straight out of the oven because they are so tender inside, so handle with care.

    Transfer to a cooling rack, and allow to cool for at least 15 minutes before attacking them!

How long these chocolate muffins stay fresh

These Chocolate Muffins will stay very fresh for 3 days which is a rare feat in the muffin world! Most muffins begin to turn stale within hours of being made. By the next day they usually need to be warmed up to resurrect them.

These muffins do start to lose freshness on Day 4 but a quick 10 second zap in the microwave is all you need to revive them to near fresh-baked-perfection.

Sounds all too good to be true right?? Well, I think you’ll just have to make these and see for yourself! I’d love to hear how long you kept yours good for. Or, if they even made it beyond Day 1 before they disappeared entirely!! 😉 – Nagi x

  • 1 3/4 cups plain flour (all-purpose flour) (Note 1)
  • 1 1/4 tsp baking soda / bi-carb (Note 2)
  • 1/2 tsp salt
  • 1/2 cup Dutch process cocoa powder , sifted (Note 3)
  • 1 tbsp instant coffee granules / powder , optional (Note 4)
  • 3/4 cup milk , full fat, HOT
  • 1/2 cup canola oil (or veg or other neutral flavoured oil)
  • 1 cup brown sugar , packed (Note 5)
  • 1 tsp vanilla extract
  • 3/4 cup sour cream or thick plain yogurt (fridge-cold fine, Note 6)
  • 1 large egg (55-60g / 2oz) (fridge-cold fine, Note 6)
  • 1 cup dark chocolate chips (for batter) (US: semi-sweet chips)
  • 1/2 cup dark chocolate chips (for topping)


  • Preheat oven to 210°C / 410°F (190°C fan). Place shelf in the top 1/3 of the oven. Line a 12-hole standard muffin tin with paper cases.
  • Sift Dry ingredients: Sift flour, baking soda and salt into a large bowl.
  • Bloom cocoa: In a separate bowl, sift the cocoa then add coffee and HOT milk. Whisk until lump-free.
  • Add remaining Wet ingredients: To the cocoa mixture, add sugar, oil, egg, sour cream and vanilla. Whisk until smooth.
  • Mix flour in: Pour Wet mix into the bowl holding the flour. Whisk until smooth and glossy. Stop once it's smooth, don't mix excessively. (Note 7)
  • Add chocolate chips: Stir in 1 cup chocolate chips.
  • Fill muffin tin: Divide the batter between the 12 holes, up to 0.5cm / 0.2" from rim of paper liner. (Note 8)
  • Top with chocolate chips: Top muffins with remaining 1/2 cup chocolate chips (just pile in middle, they spread out when baked).
  • Bake at high temp, 5 minutes: Bake for 5 minutes in preheated oven. The higher temp kick will start the rise.
  • Lower oven, 20 minutes: Turn oven DOWN to 190°C / 375°C (170°C fan). Bake a further 20 minutes, checking at 15 minutes. When toothpick comes out clean they're ready. Don't confuse melted chocolate with raw batter!
  • EAT! Rest in muffin tin for a few minutes, then transfer to cooling rack. Allow to cool for 15 minutes before devouring!


1. Self-raising flour can be used instead. If using, skip the baking soda.
2. Baking soda (bi-carb) gives the muffins a slightly better rise and makes the muffins a deeper chocolate colour (it’s a food science thing!). However, baking powder works perfectly fine – use 4 teaspoons.
3. Dutch process cocoa powder gives baked goods a more intense chocolate flavour and deep brown colour, pictured. Ordinary cocoa will work fine but expect a slightly paler colour and slightly less pronounced chocolate flavour.
4. Instant coffee granules – This age-old baking trick enhances chocolate flavour! Once baked, you can’t taste the coffee. It really works. Any old instant coffee granules fine here, no need to get premium (I use Moccona, a common Aussie brand).
5. Brown rather than white sugar – Keeps the crumb more moist. White sugar works just fine and makes the surface slightly crisper (which is appealing!) but the muffin doesn’t stay as fresh for as long.
6. Fridge-cold ingredients are ok! Usually my recipes insist on room temperature eggs and other fridge ingredients as they incorporate more easily into batters. In this recipe, fridge-cold is fine! Why? The batter is thinner so you need to whisk vigorously to incorporate anyway. But if you only have a room-temp egg, that’s fine too!
7. Over-mixing = Bad – As with all flour based cake and muffin batters, mix only as much as needed. The less you mix, the more tender your cake crumb will be. (Over-mixing by a lot → gluten in flour overworked → tougher crumb).
8. Don’t overfill the muffin case higher than 0.5cm / 0.2″ from rim because it will overflow rather than rising to a nice dome. This is because the batter is thinner than typical muffin batter (a reason why the muffin crumb is so moist).
9. Storage – All muffins are at their absolute prime freshly made, and these are no exception. However, the big difference here is that these are still moist and fresh for 3 days afterwards, even without warming them up! Once cool, store in an airtight container in the pantry. Beyond day 3, a 10 second microwave will resurrect them to warm, fresh perfection. Or freeze for up to 3 months.
