Description

These Brownie Batter Cupcakes are the ultimate chocolate indulgence dense, fudgy cupcakes topped with rich, creamy chocolate frosting. With a melt-in-your-mouth texture and intense cocoa flavor, they satisfy chocolate cravings in every bite.


Ingredients

Scale

For the Brownie Cupcakes:

  • 1 cup unsalted butter
  • 8 oz dark chocolate (70% cocoa), chopped
  • 4 large eggs, room temperature
  • 1½ cups granulated sugar
  • 1 teaspoon vanilla extract
  • ¾ cup all-purpose flour
  • ¼ cup unsweetened cocoa powder
  • ½ teaspoon salt
  • ½ cup mini chocolate chips (optional)

For the Fudgy Frosting:

  • ½ cup unsalted butter, softened
  • 3 cups powdered sugar
  • ½ cup unsweetened cocoa powder
  • ⅓ cup heavy cream
  • 2 teaspoons vanilla extract
  • Pinch of salt

Substitution Ideas:

  • Gluten-free: Replace flour with almond flour or 1:1 gluten-free baking blend
  • Dairy-free: Use coconut oil instead of butter, coconut cream for heavy cream
  • Vegan: Substitute eggs with flax eggs (4 tablespoons ground flaxseed + 12 tablespoons water)
  • Lower sugar: Reduce granulated sugar to 1 cup for less sweetness


Instructions

  • Prep Oven and Pan
    Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.

  • Melt Chocolate and Butter
    In a double boiler or microwave-safe bowl, melt butter and chopped chocolate together, stirring until smooth. Let cool 5 minutes.

  • Mix Wet Ingredients
    In a large bowl, whisk eggs and sugar until combined. Slowly add melted chocolate mixture and vanilla, whisking constantly.

  • Add Dry Ingredients
    Sift flour, cocoa powder, and salt. Gently fold into chocolate mixture until just combined. Fold in chocolate chips if desired.

  • Bake
    Divide batter among muffin cups (~¾ full). Bake 22–25 minutes, until a toothpick comes out with a few moist crumbs.

  • Make Fudgy Frosting
    Beat softened butter until light. Gradually add powdered sugar and cocoa, alternating with cream. Beat in vanilla and salt until smooth.

  • Assemble Cupcakes
    Once cupcakes are completely cool, pipe or spread frosting generously on top.

Notes

Healthier Variations

Replace half the butter with applesauce and reduce sugar by ¼ cup for a lighter version.

Use Greek yogurt in frosting to reduce fat while adding a slight tang.

Opt for higher cocoa content chocolate (85%) to intensify flavor while lowering sugar.


Serving Ideas

Serve at room temperature with cold milk, coffee, or ice cream.

Decorate with powdered sugar, berries, or salted caramel for special occasions.

Perfect for birthdays, potlucks, or elegant weeknight desserts.


Common Mistakes & Fixes

Dry cupcakes: Often from overbaking or too much flour. Spoon and level flour carefully.

Grainy frosting: Ensure butter is softened and powdered sugar is sifted; beat longer.

Sunken centers: Avoid opening oven door early; check doneness only after 20 minutes.


Storage

Room temperature: 3 days, covered.

Freezer: Unfrosted cupcakes up to 3 months in airtight containers. Thaw before frosting.

Tip: Flavors meld and cupcakes become even fudgier after a day. No reheating required.
