Recipes

Sift flour, cocoa powder and baking powder into medium bowl. Place butter in large bowl; add both sugars and whisk until well blended. Whisk in eggs 1 at a time, then vanilla extracts. Whisk in dry ingredients. Divide batter among six 1-cup ovenproof coffee mugs (about 2/3 cup in each). Top each with 2 tablespoons chocolate chips. Gently press chips into batter. Cover and refrigerate mugs at least 1 hour and up to 1 day.

Position rack in center of oven and preheat to 350°F. Let mugs with batter stand at room temperature 5 minutes. Bake uncovered until cakes are puffed and crusty and tester inserted into center comes out with thick batter attached, about 30 minutes. Cool cakes 5 minutes.
