This Cookie Butter Mug Cake is a fluffy, single-serving microwave dessert made with creamy cookie butter spread. With just four simple ingredients and about 6 minutes from start to finish, it’s the perfect quick treat when you’re craving warm caramel and spiced cookie flavors.

  • Total Time: 6 minutes
  • Yield: 1 serving 1x

Ingredients

Units Scale
1/4 cup cookie butter spread4 tbsp nonfat milk4 tbsp all-purpose flour1/2 tsp baking powder

Instructions

1. Add the cookie butter spread, nonfat milk, all-purpose flour, and baking powder to a large microwave-safe mug in the order listed.

2. Whisk until the batter is smooth and no flour lumps remain. Because the cookie butter is thick, stir firmly until fully combined.

3. Microwave on high for about 1 minute and 20 seconds, or until the cake is cooked through. The cake will rise while cooking and settle slightly after removal.

4. Let the cake cool for 2–3 minutes, then enjoy straight from the mug with a spoon.

Notes

Use nonfat, low-fat, or whole milk.

The batter will be thicker than many mug cake batters because of the cookie butter.

Do not overcook or the cake may become dry.

Enjoy warm for the best texture.

Top with whipped cream, melted cookie butter, or crushed Biscoff cookies if desired.
