Preheat your oven to 350°.

Prep your pan with butter and line with parchment.

In a sauce pan, place the broken chocolate and butter. Melt over low heat, stirring often. Once melted, remove off of the heat and add both sugars, stir and set aside.

Next sift the flour, cocoa powder, baking powder, salt and cayenne into a large bowl and set aside. To the slightly warm chocolate add in one egg at a time whisking after each additional egg. Then add spoonfuls of the flour/cocoa mixture and stir with a spatula until smooth.

Pour batter into prepared 8x8 pan and bake in preheated oven for 35-40 minutes or until a tester comes out clean. For more fudgy brownies, the tester should come out slightly coated with a thicker coat of chocolate batter, it shouldn't be runny.

Let cool and remove. Sprinkle with reserved cocoa powder and cut into desired size. If making a spicier brownie, you may want to consider keeping them a little on the small side.

Serve with vanilla bean ice cream if desired.
