Preheat your oven to 350°F (175°C) and grease an 8-inch square baking pan.

Melt 1/2 cup of unsalted butter in the microwave, then whisk with 1 cup of granulated sugar, 2 eggs, and 1 teaspoon of vanilla extract until smooth.

Sift in 1/2 cup of cocoa powder, 1/2 cup of flour, 1/4 teaspoon of salt, and 1/4 teaspoon of baking powder. Fold gently until just combined.

Fold in 1/2 cup of chocolate chips evenly throughout the batter.

Spread the brownie batter in the prepared baking pan.

Bake for 20-25 minutes until toothpick comes out with a few moist crumbs.

Allow the brownies to cool completely, then cut out using the heart-shaped cookie cutter.

Dust with powdered sugar or drizzle melted chocolate before serving.
