Step 1: Prepare the brownie base
- Preheat your oven to 350°F (175°C). Grease and line a 12-inch pizza pan or round baking dish with parchment paper.
- In a medium bowl, whisk together the melted butter and sugar until smooth. Add the eggs and vanilla extract, whisking until fully incorporated.
- Sift in the cocoa powder, flour, salt, and baking powder. Stir gently until just combined—do not overmix.
- Spread the brownie batter evenly onto the prepared pizza pan. Smooth the top with a spatula.
Step 2: Bake the brownie
- Bake for 18-22 minutes, or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs. Do not overbake.
- Allow the brownie base to cool completely in the pan.
Step 3: Make the fudge topping
- In a microwave-safe bowl, combine the chocolate chips and heavy cream. Microwave in 20-second intervals, stirring between each, until the mixture is smooth and glossy.
Step 4: Assemble the dessert pizza
- Spread the fudge topping evenly over the cooled brownie base.
- Sprinkle your chosen toppings over the fudge layer. Get creative with combinations like marshmallows, crushed cookies, or fresh fruit!
Step 5: Chill and serve
- Refrigerate the dessert pizza for 15-20 minutes to set the toppings. Slice into wedges and serve.
