4 Ingredient Cookie Butter Mug Cake

This fluffy, single serving cake is made with creamy cookie butter spread.

Next to Nutella, my favorite spread is cookie butter. Made of speculoos cookies, a crunchy European spiced biscuit cookie, the spread is similar to peanut butter except flavored with speculoos cookies. There are several versions available in the US including a popular version created by Trade Joe’s, though I’m partial to the original Biscoff spread.

I ate a lot of cake this weekend. A lot. So it seems fitting that I’m sharing a cake recipe with you on this Monday morning.

I actually created this recipe nearly a year ago, when I was writing my 5-Minute Mug Cakes*. In the end, the recipe was not put in the book because we ran out of space. I’m a little sad it wasn’t in the book, though I understand why. But now you guys get to enjoy this recipe.

This cake comes out fluffy, moist, tasting of caramel and spices. I love the caramel brown color of the spread and how it remains such a beautiful shade of brown in the final cake version as well.

I will note, the crumb of this cake is looser than some of my other mug cakes. Yes there is a way to tighten it up, but it involes adding more calories to the cake, and cookie butter isn’t exactly diet food, so I didn’t want to overdue it with this cake. It’s definitely not a cake you can dump out of your mug to eat. It’s best eaten in the mug, with a spoon. Enjoy!

Ingredients

  • 1/4 cup cookie butter spread
  • 4 tbsp nonfat milk (see note)
  • 4 tbsp all-purpose flour
  • 1/2 tsp baking powder

Instructions

  • In a large, microwave-safe mug, add all ingredients in the order listed. Mix with a small whisk until batter is smooth and no flour lumps remain. Because of the spread, this batter will be a little stiff to mix, so you'll need to use a little more strength than some of my other mug cakes.
  • Cook in the microwave for about 1 minute and 20 seconds or until cake is cooked. The cake will initially rise while cooking and will deflate slightly once it is removed from the microwave. Let cake cool a few minutes before eating.

Notes

  • I like nonfat milk, but you can use low-fat or whole milk if that's what you prefer.

  1. I added chocolate chips on top and microwaved for 10 seconds more, the best mug-cake recipe I have found!!

  2. Can you use almond milk instead of regular milk?

  3. I just received a jar of pumpkin spice cookie butter as a gift and had no idea what to do with it. This recipe with Trader Joe’s pumpkin spice cookie butter is FANTASTIC! It was very soft and smooth and not too sweet. VERY pumpkiny. Great easy recipe! 🙂
