You know, I never thought to combine brownies and muffins until my daughter asked why we couldn’t have both for her sleepover party. It made me think of all those times I’d choose between making one or the other, not realizing the answer was right in front of me.
Turns out, brownie muffins are exactly what you’d expect – the perfect mix of fudgy brownie goodness with that classic muffin shape and texture. And the best part? You don’t have to cut them into squares or deal with crumbly edges. Each one comes in its own perfectly portioned cup, ready to grab and go.

Why You’ll Love These Brownie Muffins
- Quick preparation – These muffins come together in just over 30 minutes, perfect for when you need a chocolate fix without spending hours in the kitchen.
- Simple ingredients – You only need 7 basic baking ingredients that you probably already have in your pantry – no fancy or hard-to-find items required.
- Perfect portion control – Each muffin gives you that rich, fudgy brownie experience in a convenient single-serving size, making them great for lunchboxes or afternoon treats.
- Double chocolate goodness – With both cocoa powder and real chopped chocolate, these muffins deliver that deep, intense chocolate flavor that true chocolate lovers crave.
What Kind of Chocolate Should I Use?
For these brownie muffins, you’ll want to stick with bittersweet or semisweet chocolate in the 60-70% cocoa range – this gives you the perfect balance of sweetness and deep chocolate flavor. While you might be tempted to use chocolate chips, they’re actually not the best choice here since they contain stabilizers that can affect how they melt. Instead, grab a good quality chocolate bar and chop it yourself – brands like Ghirardelli, Lindt, or Trader Joe’s dark chocolate all work great. When you’re chopping the chocolate, aim for pieces about the size of large peas, and don’t worry if you end up with some smaller shards – those will just melt into the batter and make everything more chocolatey.

Options for Substitutions
Let’s talk about what you can swap in these brownie muffins if you’re missing something:
- Chocolate: While good-quality chocolate makes a difference here, you can use chocolate chips in a pinch. Dark, semi-sweet, or even milk chocolate all work – just know that milk chocolate will make them sweeter.
- Dutch-process cocoa: Regular unsweetened cocoa powder can replace Dutch-process, but your muffins might be slightly less dark in color and a bit more acidic in taste. If using regular cocoa, add a tiny pinch (1/8 teaspoon) of baking soda to balance the acidity.
- Butter: You can swap butter with an equal amount of neutral oil like canola or vegetable oil. The texture will be slightly different – more moist but less rich. Coconut oil works too, but might add a slight coconut flavor.
- All-purpose flour: Cake flour works great here for an even more tender crumb – use the same amount. I wouldn’t recommend whole wheat flour as it would make these too heavy.
- Granulated sugar: Light brown sugar can replace up to half the granulated sugar, which will give a slight caramel note. Just don’t use all brown sugar as it will change the texture too much.
Watch Out for These Mistakes While Baking
The biggest challenge when making brownie muffins is avoiding overbaking, which can turn these fudgy treats into dry, crumbly disappointments – pull them from the oven when a toothpick inserted comes out with a few moist crumbs, not completely clean. A common mistake is improperly melting the chocolate and butter, which can result in a grainy texture; instead, use a double boiler or microwave in short 20-second bursts, stirring between each interval until just melted. When measuring the cocoa powder and flour, avoid the temptation to pack them into the measuring cups – a light spoon-and-level method will give you the right amount and prevent dense, heavy muffins. For the best texture, make sure your eggs are at room temperature before mixing, and don’t overmix the batter once the dry ingredients are added – stop as soon as everything is just combined.

What to Serve With Brownie Muffins?
These rich chocolate muffins are perfect for pairing with a cold glass of milk or a hot cup of coffee! If you’re serving them for dessert, try adding a scoop of vanilla ice cream on top while they’re still a bit warm – the ice cream will start to melt and create an amazing sauce. For a quick breakfast or afternoon snack, I like to serve them with fresh berries on the side – strawberries and raspberries work especially well with the chocolate flavor. You can also dress them up with a drizzle of caramel sauce or a dollop of whipped cream if you’re feeling fancy.
Storage Instructions
Counter Storage: These brownie muffins stay fresh at room temperature for up to 3 days when kept in an airtight container. I like to place a paper towel at the bottom of the container to absorb any excess moisture and keep them from getting too dense.
Refrigerate: Pop these chocolatey treats in the fridge in a sealed container, and they’ll stay good for up to a week. The cool temperature might make them a bit firmer, but that’s actually pretty nice – especially if you like that fudgy texture!
Freeze: These muffins are perfect for freezing! Just wrap them individually in plastic wrap, then place them in a freezer bag for up to 3 months. When you’re craving something sweet, grab one and let it thaw at room temperature for about an hour.
Warm Up: Want that fresh-from-the-oven experience? Pop a muffin in the microwave for 10-15 seconds, and you’ll get that wonderful melty chocolate goodness back. Just be careful not to overheat, or they might dry out!

Ingredients
- 1/8 tsp salt
- 3/4 cup granulated sugar (for sweetness and tender crumb)
- 2 large eggs
- 2/3 cup bittersweet chocolate (coarsely chopped for easy melting)
- 2 tbsp all-purpose flour
- 1/2 cup unsalted butter (cut into small pieces for even melting)
- 1/3 cup Dutch-process cocoa powder (I use Ghirardelli brand)
- 1/3 cup all-purpose flour
Step 1: Preheat and Prepare Your Baking Equipment
Start by preheating your oven to 350℉ (180℃).
Line 12 muffin cups with liners and set them aside.
This will ensure your brownies don’t stick and are easy to remove once baked.
Step 2: Melt Chocolate and Butter
In a medium heatproof bowl, place your chocolate and butter.
Heat the mixture in the microwave in 20-second intervals, stirring between each interval, until fully melted.
Alternatively, you can melt them by placing the bowl over a saucepan of simmering water, stirring occasionally.
Once melted, set the bowl aside to cool slightly.
Step 3: Prepare Dry Ingredients
In a small bowl, sift together the flour, cocoa powder, and salt.
This will combine and aerate the ingredients, making for a smoother batter.
Set the dry mixture aside for later use.
Step 4: Combine Wet Ingredients
Using an electric mixer fitted with the whisk attachment or a handheld mixer, whisk the eggs and sugar on high speed until the mixture is thick and pale.
This should take about 4 minutes.
Reduce the speed to low and slowly blend in the melted chocolate mixture.
Once well combined, stop the mixer.
Step 5: Incorporate Dry Ingredients
Add the sifted flour mixture to the wet ingredients.
Using a rubber spatula, gently fold the dry ingredients into the wet mixture just until combined.
Be cautious not to overmix, as this could affect the texture of your brownies.
Step 6: Fill and Bake the Brownie Muffins
Divide the brownie batter evenly among the prepared muffin cups, filling each about ¾ full.
If desired, sprinkle extra chopped chocolate on top of each muffin before baking.
Bake in the preheated oven for 13-15 minutes or until a toothpick inserted into the center of a brownie muffin comes out with moist crumbs but not dry.
Be careful not to overbake to ensure a moist and fudgy brownie texture.
Step 7: Cool and Enjoy
After baking, transfer the brownie muffins to a wire rack and let them cool for at least 10 minutes before removing them from the pan.
Allow them to cool completely on the wire rack before serving.
Enjoy your deliciously moist and chocolaty brownie muffins!
