• Perfect single-serving dessert
• Easily customizable with toppings

Ingredients

• 4 tablespoons all-purpose flour
• 2 tablespoons sugar
• 1/4 teaspoon baking powder
• Pinch of salt
• 2 tablespoons cookie butter (such as Biscoff)
• 2 tablespoons melted butter
• 3 tablespoons milk
• 1/2 teaspoon vanilla extract

How to Make Cookie Butter Mug Cake

1. In a microwave-safe mug (at least 10–12 ounces), add the flour, sugar, baking powder, and salt. Stir well to combine.
2. Add the cookie butter and melted butter to the mug. Stir until mostly incorporated.
3. Pour in the milk and vanilla extract. Mix until you have a smooth batter with no dry spots.
4. Microwave on high for 60–75 seconds. The cake should rise and look set on top but still be soft in the center.
5. Let the mug cake cool for about 1 minute before adding toppings.

Tips for the Best Mug Cake

• Don’t overcook it. Mug cakes continue to set as they cool, so stop cooking as soon as the center looks just set.
• Use a larger mug to prevent overflow.
• Stir thoroughly to avoid flour pockets at the bottom.
• Every microwave is different—start with 60 seconds and add time if needed.

Serving Ideas

This cookie butter mug cake is delicious on its own, but it’s even better with a little something extra on top. Try drizzling warm cookie butter over the cake, adding a spoonful of vanilla frosting, or topping it with whipped cream and crushed cookies. For a fun presentation, sprinkle with festive sprinkles or serve with a scoop of vanilla ice cream on the side.

Storage

This mug cake is best enjoyed fresh and warm. Because it’s a single-serving dessert, leftovers aren’t recommended. If the cake sits too long, it can dry out.
