Double Chocolate Buttermilk Muffins

These double chocolate buttermilk muffins are incredible! Moist, chocolatey goodness that is perfect for breakfast with your coffee or an anytime snack.

There are muffins and then there are these muffins. The kind that look like they came from a bakery case — domed tops, chips melted into the surface, deep chocolate color all the way through. I started making these because I wanted a chocolate muffin that actually tasted like chocolate and not like a dry cake in a paper cup. Cocoa powder in the batter plus chocolate chips folded in plus more chips pressed on top — that’s what double chocolate means here, and that’s what makes the difference.

The buttermilk is what keeps them from drying out. The optional espresso powder is what makes people ask what’s in these. And the two-sugar combination is what gives you that slightly complex sweetness instead of just flat sugar. Make them once and this will become your go-to recipe every time someone in your house asks for a chocolate muffin.

Ingredients for Chocolate Muffins

INGREDIENT NOTES

Cocoa powder: Use unsweetened cocoa powder. Dutch-process gives you a deeper, less bitter chocolate flavor and a darker color — it’s the better choice here if you have it. Natural cocoa works too but produces a slightly lighter, more acidic result.

Two sugars: Granulated sugar gives structure and a clean sweetness. Brown sugar adds moisture and a hint of molasses depth. Together they produce a crumb that stays tender without being dense. Don’t substitute all white or all brown — the combination matters.

Buttermilk: Full-fat buttermilk is specified and it matters. The acidity reacts with the baking soda to give these muffins lift, and the fat content is what keeps them moist for days. No buttermilk? Add 1 tablespoon of white vinegar to a measuring cup and fill to 1 cup with whole milk. Stir, wait 5 minutes, use exactly the same way.

Espresso powder: Listed as optional but genuinely recommended. A teaspoon of instant espresso powder doesn’t make these taste like coffee — it intensifies the chocolate flavor in a way that’s hard to pinpoint but immediately noticeable. This is the ingredient people ask about when they can’t figure out why yours taste richer than theirs.

Almond extract: ¼ teaspoon alongside the vanilla. It adds a subtle warmth that’s more of a feeling than a flavor — you won’t taste almond, but the muffins will taste more complex. Skip it if you prefer or have an allergy — the muffins are still excellent without it.

Chocolate chips: 1½ cups total, divided. 1 cup into the batter, ½ cup on top. Semi-sweet is classic. Dark chocolate chips push these into more sophisticated territory. Mini chips distribute more evenly in the batter if you want chocolate in every single bite.

How Do You Make Double Chocolate Muffins?

Start with your dry ingredients. In a medium bowl, whisk together the flour, cocoa powder, both sugars, baking powder, baking soda, espresso powder if using, and salt. Whisking rather than sifting is fine — just make sure everything is evenly combined so you don’t get pockets of baking soda in a finished muffin.

In a separate bowl, whisk together the buttermilk, oil, eggs, vanilla, and almond extract until smooth. Make a well in the center of your dry ingredients and pour the wet ingredients in. Use a spatula to fold — not stir, not beat — just until no dry flour is visible. The batter will look lumpy and that’s exactly right. Stop there.

Fold in 1 cup of chocolate chips. Then stop mixing. Overmixing is the number one reason muffins come out dense and rubbery instead of light and tender — the more you work the batter after the flour goes in, the more gluten develops. Mix until combined and get it in the oven.

Get your muffins into the tin and into the oven quickly. Once the wet ingredients hit the buttermilk and baking soda, the leavening reaction starts — the longer the batter sits, the less lift you’ll get. Fill each cup about ⅔ full using an ice cream scoop for consistent size, then scatter the remaining ½ cup of chips on top of each one.

Bake at 350°F for 22–25 minutes. The toothpick test applies here — insert into the center of a muffin and look for moist crumbs, not wet batter. The chips on top will be soft and slightly melted at this point, which is exactly what you want. Cool in the pan for 10 minutes, then transfer carefully to a wire rack. Don’t flip the pan upside down — you’ll smash those surface chips that you worked to get right.

Tips

Don’t overmix. Fold the wet into the dry until just combined — lumpy batter is correct batter. Every extra stir develops gluten and makes the muffins tougher. Stop as soon as no dry flour is visible.

Get them in the oven fast. Buttermilk and baking soda start reacting the moment they meet. Batter that sits on the counter loses lift. Mix, scoop, bake — in that order without unnecessary pausing.

Use an ice cream scoop. Consistent size means consistent bake time. Unevenly filled cups mean some are overdone while others are underdone on the same pan.

Reserve chips for the top. Don’t skip the step of scattering chips on top before baking. It’s what gives these the bakery look and adds a melted chocolate layer on the surface that you don’t get any other way.

Don’t flip the pan. Muffins with chips on top need to be lifted out, not turned over. Cool 10 minutes in the pan and lift each one carefully.

Espresso powder tip: If you’re on the fence, add it. You will not taste coffee. You will taste more chocolate than you thought a muffin could have.

Yummy Variations

Mocha muffins: Add 2 teaspoons of instant espresso powder instead of 1, and swap the almond extract for ½ teaspoon of coffee extract. The coffee flavor becomes more pronounced without being overwhelming.

Mint chocolate: Replace the almond extract with ¼ teaspoon of peppermint extract. Mint chocolate chip muffin — just without the chips being mint flavored. Works better than it sounds.

Nutty chocolate: Fold in ½ cup of chopped walnuts or pecans with the chocolate chips. The toasted nut flavor alongside the cocoa is a classic combination for good reason.

Stuffed version: Drop a tablespoon of batter into each muffin cup, add a frozen peanut butter ball or a teaspoon of Nutella, then cover with remaining batter. The filling melts during baking into a molten center.

White chocolate chips: Swap the semi-sweet chips for white chocolate. The contrast of deep cocoa batter and sweet white chocolate is unexpectedly good and makes for a striking presentation.

These freeze so well that I keep a batch in the freezer almost permanently — 30 seconds in the microwave and you have a warm chocolate muffin on demand, which is a level of breakfast preparedness I fully stand behind. Make a double batch the first time so you have enough to freeze. And if you’re building out a full muffin rotation, the Cranberry Orange Muffins are the next ones to try — completely different flavor profile but the same kind of bakery-style result.
