The Best Chocolate Brownie Cookies

Here’s a warm, mini-sized treat that brings the best of both worlds: the fudgy heart of a brownie and the soft chew of a cookie. These Mini Chocolate Brownie Cookies come together easily, bake quickly, and always feel a little magical fresh from the oven.

Ingredients

  • 1 cup semi-sweet chocolate chips
  • 2 tbsp unsalted butter
  • 1/2 cup granulated sugar
  • 2 tbsp brown sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 1/2 cup all-purpose flour
  • 2 tbsp cocoa powder
  • 1/4 tsp baking powder
  • Pinch of salt
  • Optional: A few extra chocolate chips for topping
  • Swap: Use dark chocolate chips for a deeper flavor

Steps

  1. Melt the chocolate and butter together in a microwave-safe bowl, stirring until smooth. Let it cool for a minute warm is fine, hot is not.
  2. Whisk in the sugars, then add the egg and vanilla. The mixture will look glossy and thick.
  3. Fold in the dry ingredients (flour, cocoa, baking powder, salt). Don’t worry if the batter feels dense that’s what makes the cookies brownie-like.
  4. Scoop teaspoon-sized mounds onto a lined baking sheet. Keep them small so they bake into perfect minis.
  5. Add a few extra chocolate chips on top if you want those pretty melty pools.
  6. Bake at 350°F for 8–9 minutes. They should look slightly soft in the center they’ll set as they cool.
  7. Let them rest on the tray for 5 minutes before moving. Mini cookies are delicate when warm.

Chef’s Tips

  • If the batter feels too loose, chill it for 10 minutes it helps them hold their shape.
  • Pull them from the oven while still soft to keep that rich brownie chew.
  • Store in an airtight container with a small piece of bread to keep them fudgy for days.

Variations

  • Mint Chip: Add 1/4 tsp peppermint extract and swap half the chocolate chips for mint chips.
  • Salted Brownie: Sprinkle each cookie with a tiny pinch of flaky sea salt before baking.
  • Peanut Butter Swirl: Press a mini dollop of peanut butter on top of each mound before baking.
