please help me figure out what went wrong

ingredients

• 1/2 cup granulated sugar

• 4 large eggs

• 1/2 cup unsweetened cocoa powder

• 2 tsp vanilla extract

• 1/4 tsp kosher salt

• 1/2 tsp baking powder

• 1/2 cup unsalted butter

• 1 cup semisweet chocolate chips

steps

1. Preheat the oven to 350F and line a brownie pan (or cake pan in my case) with parchment paper.

2. In a large mixing bowl, whisk together the sugar, eggs, and vanilla until light and frothy. 

3. Mix in the cocoa powder, salt, and baking powder.

4. In a heat-safe bowl, add butter and chocolate chips. Microwave in 30 second intervals until smooth (~60s for me).

5. Pour melted chocolate into the large mixing bowl and mix to combine. The consistency is thick and similar to brownie batter.

6. Bake for 15-17 minutes.
