To prepare a title kahlua brownies baked goods recipe, first you need to prepare the brownie batter. First, you'll need the following ingredients: Preheat the oven to 350?F (180?C) and grease and flour two 8-inch square pans. Add the flour, cocoa, baking powder, salt, and nutmeg to the bowl and mix until the ingredients are evenly combined. Pour the wet ingredients into the dry ingredients and stir to combine. Sift in the chocolate chips and beat the mixture with an electric mixer until it's light and fluffy, about 2 minutes. In another bowl, combine the butter, brown sugar, eggs, vanilla and vanilla extract. Beat the batter with the mixer on medium-high speed for 1 minute, then scrape down the sides of the mixing bowl with your rubber spatula to mix it all together.
