If you love the edge pieces of brownies, you'll love these "all edge" sweet and spicy brownies. Every piece is surrounded in chewy "edge" brownie goodness!
Preheat the oven to 375ºF. Coat the inside of 6 cups of a muffin tin with butter.
In a mixing bowl, stir together the flour, cocoa powder, sugar, salt, cayenne, baking powder, and cinnamon until evenly combined.
Cut the butter into chunks, then microwave until melted (about 30 seconds). Let the butter cool slightly while you add the eggs and vanilla to the bowl with the dry ingredients (don't stir them in just yet). Finally, pour the melted butter into the bowl and then stir until a thick, even brownie batter has formed.
Divide the batter between the greased cups, then bake for 20 minutes, or until the centers are puffed and the edges are browned. Remove the brownies from the oven and allow to cool (or eat warm!).
