Ultimate Fudgy Brownie Sundaes My GoTo Brownie and Ice Cream

Instructions:

1. Preheat oven to 350°F (175°C). Line the baking pan with parchment paper, leaving an overhang on two sides.
2. Combine butter and chocolate in a double boiler (or heatproof bowl over simmering water). Stir until melted and smooth.
3. Remove from heat and whisk in both sugars until well combined.
4. Whisk in the eggs one at a time, then stir in the vanilla extract.
5. In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder.
6. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
7. Pour the batter into the prepared pan and spread evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
8. Let the brownies cool completely in the pan before cutting. (Using the parchment paper overhang, lift the whole brownie slab out of the pan)
9. Combine cream, sugars, cocoa powder, and salt in a saucepan. Bring to a simmer over medium heat, stirring constantly.
10. Remove from heat and stir in the chocolate and butter until melted and smooth. Stir in the vanilla extract.
