Chocolate Cupcakes

Published: by . Leave a Comment

There are chocolate cupcakes, and then there are these Chocolate Cupcakes. Max calls them the "chocolate explosion" because they are impossibly dark, rich, and topped with a mountain of fudgy buttercream. We baked a batch last rainy Sunday, and I think we spent more time licking the frosting off our fingers than actually waiting for them to cool. If you are looking for the ultimate birthday treat or just a cure for a cocoa craving, this is the one.

These Chocolate Cupcakes are incredibly moist, dark, and fluffy, topped with a rich homemade chocolate buttercream frosting. The addition of hot coffee blooms the cocoa for an intense chocolate flavor.

Why You Will Love This Chocolate Cupcakes

You will love this recipe because it produces the moistest crumb imaginable without being greasy. Unlike dry, crumbly bakery versions, these use a mix of oil and buttermilk to stay tender for days. The secret weapon is blooming the cocoa powder in hot liquid, which wakes up the chocolate flavor and makes them taste incredibly expensive. Plus, they are sturdy enough to pile high with frosting and sprinkles, just like the picture.

How To Make Chocolate Cupcakes

We skip the mixer for the batter—just two bowls and a whisk are all you need. We whisk the dry ingredients in one bowl and the wet ingredients in another, then combine them. The magic step is slowly pouring in hot coffee (or water) at the end; it makes the batter very thin, but trust the process! It bakes up into a light, airy sponge that pairs perfectly with our whipped chocolate buttercream.

Chocolate Cupcakes Ingredients

The Moist Sponge

  • 1 ½ cups all-purpose flour
  • 1 ½ cups granulated sugar
  • ¾ cup unsweetened cocoa powder (Dutch-process gives that dark color)
  • 1 ½ teaspoons baking soda
  • ¾ teaspoon baking powder
  • ¾ teaspoon salt
  • 2 large eggs; room temperature
  • ¾ cup buttermilk; room temperature
  • ¼ cup vegetable oil
  • 1 teaspoon vanilla extract
  • ¾ cup hot brewed coffee (or hot water)

The Fudge Frosting

  • 1 cup (2 sticks) unsalted butter; softened
  • ¾ cup unsweetened cocoa powder
  • 3 cups powdered sugar
  • 3–4 tablespoons heavy cream
  • 1 teaspoon vanilla extract
  • Chocolate sprinkles (jimmies) for garnish

Step by Step Method

Prep and Whisk Dry

  • Preheat oven to 350°F (175°C) and line a muffin tin with 12 paper liners.
  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.

Mix the Wet Ingredients

  • In a medium bowl, whisk the eggs, buttermilk, oil, and vanilla extract until combined.
  • Pour the wet mixture into the dry ingredients and mix until just combined (don't overmix yet!).

The Hot Liquid Trick

  • Slowly pour in the hot coffee (or hot water) while whisking gently.
  • The batter will be very thin and liquidy—this is normal and ensures a moist cake!

Bake

  • Fill cupcake liners about ⅔ full.
  • Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean.
  • Let them cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before frosting.

Whip the Frosting

  • Beat the softened butter until creamy. Add the cocoa powder and beat again.
  • Gradually add the powdered sugar alternating with the heavy cream.
  • Whip on high speed for 3 minutes until fluffy.
  • Pipe a tall swirl onto each cooled cupcake and top immediately with chocolate sprinkles.

MAX’S REACTION

"I helped put the sprinkles on! The frosting tastes like a chocolate cloud. Mom says I can't have the coffee part, but she said the heat makes the coffee disappear and just leaves the chocolate taste. It works!"

What Pairs Well With Chocolate Cupcakes

These are rich, so a cold glass of milk is the classic pairing. For a birthday party spread, they look great alongside a bowl of fresh strawberries or raspberries to cut the sweetness. If you are serving these to adults, a glass of red wine or a cappuccino brings out the deep cocoa notes beautifully.

Chocolate Cupcakes Variations

Peanut Butter Lovers

Swap the chocolate buttercream for a fluffy peanut butter frosting. Top with a mini peanut butter cup for the ultimate candy bar vibe.

Hidden Center

Use a small knife or apple corer to remove the center of the baked cupcake. Fill it with raspberry jam, salted caramel, or chocolate ganache for a gooey surprise.

Black Forest

Fold chopped cherries into the batter and top with whipped cream and a maraschino cherry instead of buttercream for a retro twist.

Mocha Crunch

Add a tablespoon of instant espresso powder to the frosting and top with chocolate-covered espresso beans for a caffeine kick.

Equipment

  • 12-cup muffin tin
  • Cupcake liners
  • Whisk
  • Mixing bowls
  • Electric mixer (hand or stand, for the frosting)
  • Piping bag and large star tip (like Wilton 1M)
  • Mom Tip: If you don't have buttermilk, mix regular milk with a teaspoon of vinegar and let it sit for 5 minutes.

Storage / Make Ahead / Serving Tips

Room Temperature

Frosted cupcakes can stay at room temperature in an airtight container for up to 2 days. The sugar in the frosting acts as a preservative.

Fridge Storage

If your kitchen is hot, store them in the fridge for up to 4 days. Let them come to room temperature before eating so the buttercream softens up again.

Freezing

Unfrosted cupcakes freeze beautifully for up to 3 months. Wrap them individually. You can also freeze frosted cupcakes; just flash freeze them on a tray first so the frosting doesn't get squished.

Top Tips for Best Chocolate Cupcakes

The temperature of your ingredients matters! Ensure your eggs and buttermilk are at room temperature so they emulsify properly with the oil. Also, do not skip the hot liquid step—it "blooms" the cocoa powder, releasing flavor that cold milk just can't unlock. Finally, fill the liners only ⅔ full; if you overfill, they will spill over and make a mess of your pan.

Chocolate Cupcakes Frequently Asked Questions

Can I use water instead of coffee?

Yes! Simple chocolate cupcake recipe versions often use hot water. Coffee just enhances the chocolate flavor without making it taste like a latte.

Why are my cupcakes dry?

You might have overbaked them or measured the flour incorrectly. Spoon and level your flour rather than scooping the cup into the bag.

Can I make these gluten-free?

Yes, use a high-quality 1:1 gluten-free baking flour blend in place of the all-purpose flour. The moist batter adapts well to gluten-free flour.

What creates the high swirl?

We used a piping bag with a 1M or 2D tip. Start in the center, spiral out to the edge, and then spiral upward, lifting pressure at the very top.
