This single serving cookie butter cake is the perfect sweet treat for one. With just five ingredients, you'll get a fresh baked warm cake, with a slightly gooey center.
Preheat oven to 350°F. In a small bowl, combine all ingredients and mix vigorously with a small whisk until batter is completely smooth.
Grease an oven-safe mug, bowl, or ramekin (big enough so that the batter will fill 2/3 when poured in; I used a wide mug.) Pour batter into bowl. Bake for about 16-18 minutes, until cake looks completely cooked and center is mostly set. Let cake cool a few minutes before eating. I use a spatula to loosen the edges and then placed mine into a 4 oz ramekin for serving.
