An oldie but goodie! This was one of the first recipes I made when I started my account but had to bring it back for all the holiday baking because this recipe is sooo good & simple!
Mix all ingredients together. Split the batter into two parts. Add 1-2 tablespoons of cacao powder to one half of the batter. Roll into balls using both batters to create a marbled effect. Bake at 350°F for 10-12 minutes.
