To prepare a white chocolate chunk brownies nuts recipe, first you need to prepare your ingredients. First, you'll need the following ingredients: White chocolate chips (optional) 12 cup (60 ml) granulated sugar 1 tablespoon (2.5 g) vanilla extract Instructions: Place the chopped nuts in the microwave-safe bowl and microwave for 30 seconds, or until the nuts are melted. Remove from microwave and set aside. In the bowl of an electric mixer, cream the butter and sugar until light and fluffy. Add the vanilla and beat on medium speed until fluffy, about 2 minutes. Gradually add the flour, beating after each addition until it's just combined. Pour the batter into the prepared brownie pan and bake for 20 minutes at 325 degrees F.
