Rich espresso and loads of chocolate come together in these bite-sized fudgy morsels. You'll get crunchy tops and gooey, melt-in-your-mouth centers packed with chunks of chocolate. Mixing up two varieties of cocoa and a punch of espresso makes these mocha-flavored mini treats stand out. Chocolate fans and coffee lovers both go wild for these. They're great when you just want a little treat—or a whole handful. Super convenient so you won't overdo it all at once.

I whipped these up when work stress was through the roof and I needed something punchy but snackable to last the week. Messed around with the espresso and chocolate until I found the winning formula. Whenever I show up to events now, folks expect these—especially my sister who doesn't usually love sweet stuff. The final stamp of approval? My super picky, espresso-obsessed dad jokes about dessert coffee, but now grabs extra to stash in his freezer for his daily brew.

Luxurious Ingredients

  • Bittersweet chocolate: Brings tons of deep flavor with just the right amount of sweet
  • Fine sea salt: Boosts the flavors and makes everything pop
  • Espresso powder: Adds legit coffee goodness and ramps up the chocolate
  • All-purpose flour: Holds everything together but keeps the focus on rich choc
  • Brown sugar: Makes everything stickier and more tender with a hint of molasses
  • Granulated sugar: Heightens the sweetness and gives the tops that crackly look
  • Dutch-process cocoa powder: Amps up the deep chocolate vibes thanks to how it's made
  • Neutral vegetable oil: Keeps everything moist even if they chill in the fridge
  • Black cocoa powder: Adds a European-style, bold chocolate strength
  • Pure vanilla extract: Lifts the chocolate and adds yummy, fragrant notes
  • Room temperature eggs: Mix in easy for that perfectly soft bite—no toughness

Simple Instructions

Bake With Confidence:
Crank the oven to 350°F, then bake 15-18 minutes. You're waiting for set tops with those lovely little cracks. Cool before pulling them out.
Fill For Evenness:
Spoon batter into mini muffin pans—just about three-quarters full works best.
Mix In The Good Stuff:
Drop in plenty of chopped chocolate at the end for extra melty magic.
Add Your Drys:
Slowly sieve in flour, both kinds of cocoa, salt, and espresso powder, blending just enough to come together.
Combine Chocolate:
Pour the cooled, melted chocolate (with oil) slowly into your whipped egg mixture while mixing.
Beat It Up:
Grab a whisk. Beat together sugars, eggs, and vanilla for about five minutes until it gets pale and fluffy.
Melt Everything:
Use a heatproof bowl over simmering water to melt chocolate with oil. Stir until glossy and smooth, then let it rest a bit off the heat.

Tasty Sides

These rock alongside hot coffee, a scoop of vanilla ice cream, a handful of fresh berries, or even a little glass of port if you're feeling fancy.

Tasty Twists

Want a new spin? Mix in some orange zest for zing, cayenne for a touch of heat, or walnuts for crunch. A splash of peppermint is a winner for festive snacks.

Storing Made Easy

Pop them in something airtight and they'll last four days on the counter. Or freeze up to three months. Let thaw out, or microwave a few seconds for that gooey fresh-from-the-oven feel.

Easy Fixes

If they’re kind of cakey, use a bit less flour next time. Sticking? Freeze the tin a bit before you try to get them out. Good espresso powder makes the mocha taste shine.

Frequently Asked Questions

→ Why does the eggs and sugar need to go that long in the mixer?
Mixing those together for about 5-6 minutes gets extra air in so you end up with that crackly, shiny top everyone loves. Don’t skip or rush this—it really matters for the texture.
→ What’s black cocoa powder, and can I swap it out?
Black cocoa is a super-dark, extra-processed cocoa with loads of flavor. Can’t find it? Just use more Dutch cocoa, it’ll still turn out great.
→ Do I actually need espresso powder in these brownies?
Nope, you can leave it out. The chocolate still shines if you skip it, but espresso powder gives a boost without making it taste like coffee.
→ What’s the best way to keep these mini brownies fresh?
Pop them in a container with a good lid and keep at room temp for up to four days. Or stash in the freezer for three months. Let them warm up at room temp after freezing before eating.
→ Can I put other stuff in these brownie bites?
For sure! Try tossing in caramel bits, mint chocolate, or nuts, just be sure not to add more than the amount of chocolate chunks the mix calls for.

Difficulty: Intermediate

Cuisine: Sweet American Treat

Yield: 36 Servings (36 little brownie bites)

Dietary: Vegetarian

Ingredients

01 28g (¼ cup) instant espresso powder
02 120g (1 cup) plain flour
03 127g (4.5 oz) dark chocolate, coarsely chopped
04 142g (⅔ cup) packed light brown sugar
05 2 teaspoons vanilla extract
06 ½ teaspoon fine salt
07 150g (¾ cup) neutral or olive oil
08 85g (3 oz) premium bittersweet chocolate bar
09 3 large eggs brought to room temp
10 63g (¾ cup) Dutch-process cocoa powder
11 200g (1 cup) white granulated sugar
12 21g (¼ cup) black cocoa powder

Instructions

Step 01

Set your oven to preheat at 350°F. Grease the cups of a mini muffin pan generously with softened butter so the bites release easily later on.

Step 02

Make a DIY double boiler by putting a heat-safe bowl over a pot with a little simmering water. Drop in your bittersweet chocolate and oil, stirring until it’s completely smooth and melted. Leave it to cool a bit while you handle the next step.

Step 03

Drop your eggs, vanilla, and sugars into a large bowl. Use a mixer on high for about 5-6 minutes until the mixture turns fluffy, doubles in volume, and lightens in color. Don’t skip this—it’s what gets you that perfect crackly top!

Step 04

Slowly pour your slightly cooled chocolate-and-oil combo into the whipped egg mixture while you keep the mixer on low. Blend until it transforms into a smooth batter.

Step 05

Toss in flour, the cocoa powders, salt, and espresso powder. Stir gently and stop once it’s just mixed in. Overmixing can mess up the texture!

Step 06

Stir in the chopped bittersweet chocolate pieces until they’re evenly spread through the batter using a spatula.

Step 07

Spoon or pipe your batter into the muffin pan, filling each cup about ¾ of the way up to allow for a gentle rise.

Step 08

Pop the pan into your hot oven and bake for around 15-18 minutes. They’re done when a toothpick stuck in comes out with only a few soft crumbs clinging to it. Don’t overdo it, or you’ll lose that fudgy texture!

Step 09

Take the bites out of the oven and let them cool in the pan a bit before carefully removing. Let them finish setting as they cool. Bake the rest of the batter in batches.

Notes

  1. Use top-quality bittersweet chocolate brands like Guittard or Valrhona for the best results.
  2. If you run out of black cocoa powder, use a total of 84g of Dutch-process cocoa powder instead.
  3. To get that shiny brownie top, it's essential to beat the eggs and sugar for the full 5-6 minutes.
