Ingredients

To make this delightful Peanut Butter Cake in a Mug, you’ll need the following ingredients:

  • 4 tablespoons self-rising flour – This provides structure and helps the cake rise. If you don’t have self-rising flour, you can make your own by combining 1/2 cup all-purpose flour, 3/4 teaspoon baking powder, and a pinch of salt.
  • 3 tablespoons granulated sugar – Adds sweetness to the cake. You can adjust this amount based on your preference.
  • 4 tablespoons creamy peanut butter – The star ingredient! It adds richness, a nutty flavor, and moisture to the cake.
  • 3 tablespoons whole milk – Provides moisture and helps create a soft texture.
  • 3 tablespoons salted sweet cream butter, melted – Adds flavor and richness. If you use unsalted butter, add a small pinch of salt to balance the flavors.
  • 1/2 teaspoon pure vanilla extract – Enhances the overall flavor of the cake.
  • 1 tablespoon creamy peanut butter (optional, for garnish) – A final touch for extra peanut butter goodness!

Optional Add-Ins

  • Chocolate chips – Stir in a tablespoon of mini chocolate chips for a peanut butter-chocolate combo.
  • Chopped nuts – Add a crunchy texture with chopped peanuts, almonds, or cashews.
  • Cinnamon or nutmeg – A pinch of these spices adds warmth to the cake.

Step-by-Step Instructions

Step 1: Prepare Your Mug

Choose a microwave-safe mug that holds at least 10–12 ounces to prevent the batter from overflowing. Lightly grease the inside of the mug with butter or non-stick spray for easy removal.

Step 2: Mix Dry Ingredients

In the mug, combine 4 tablespoons of self-rising flour and 3 tablespoons of granulated sugar. Stir well to ensure an even distribution.

Step 3: Add Wet Ingredients

Add the 4 tablespoons of creamy peanut butter, 3 tablespoons of whole milk, 3 tablespoons of melted butter, and 1/2 teaspoon of vanilla extract. Stir thoroughly until the batter is smooth and fully combined.

Step 4: Microwave the Cake

Microwave on high power for 60–90 seconds. The cake should rise and set, with a soft, slightly firm top. If it still looks undercooked, microwave it in 10-second intervals until done.

Step 5: Add Garnish

For an extra peanut butter touch, spread 1 tablespoon of creamy peanut butter on top while the cake is still warm.

Step 6: Enjoy!

Let the cake cool for about 1–2 minutes before digging in. Serve as is or with a scoop of vanilla ice cream for an indulgent treat!

3. Cake is Too Dense?
