Preparation

• Preheat the oven to 350°F (175°C). Grease and line a baking sheet with parchment paper.
• In a large bowl, cream together the softened butter and sugar until light and fluffy.
• Beat in the eggs one at a time, then stir in the vanilla extract.
• In another bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually add to the butter mixture, mixing until just combined.
• Spread the batter evenly onto the prepared baking sheet.
• Bake for 15-20 minutes, or until a toothpick inserted in the center comes out clean.
• Allow the brownies to cool completely in the pan on a wire rack.
• Once cooled, cut the brownies into squares or rectangles.
• Place a scoop of vanilla ice cream between two brownie pieces to make sandwiches.
• Wrap the sandwiches in plastic wrap and freeze for at least 1 hour before serving.
