What Are Chocolate Peanut Butter Mug Cakes?
A Chocolate Peanut Butter Mug Cake is a personal-sized dessert made by mixing simple ingredients in a mug and cooking it in the microwave. The result is a moist, flavorful cake featuring the classic combination of chocolate and peanut butter. It’s an excellent option for those seeking a quick dessert without making a full-sized cake.
Unlike traditional cakes that require multiple steps, preheating, and precise measurements, mug cakes are forgiving and adaptable. They allow you to experiment with different flavors, mix-ins, and toppings while requiring only a few minutes to prepare.
Ingredients You’ll Need
To make this delightful treat, gather the following ingredients:
- All-Purpose Flour: Forms the base of the cake.
- Unsweetened Cocoa Powder: Provides rich chocolate flavor.
- Granulated Sugar: Adds sweetness.
- Baking Powder: Helps the cake rise.
- Milk: Adds moisture; dairy or non-dairy alternatives work.
- Vegetable Oil or Melted Butter: Adds richness and moisture.
- Vanilla Extract: Enhances overall flavor.
- Creamy Peanut Butter: For that luscious peanut butter taste.
- Optional Add-ins: Chocolate chips, a pinch of salt, or a sprinkle of powdered sugar for garnish.
- Nut Butter Variations: Swap peanut butter with almond or cashew butter for a different twist.

Step-by-Step Recipe
Ingredients:
- 1/4 cup all-purpose flour
- 2 tablespoons unsweetened cocoa powder
- 2 tablespoons granulated sugar
- 1/4 teaspoon baking powder
- 1/4 cup milk
- 2 tablespoons vegetable oil or melted butter
- 1/4 teaspoon vanilla extract
- 1 tablespoon creamy peanut butter
- Optional: 1 tablespoon chocolate chips
- Optional: 1/2 teaspoon cinnamon for added warmth
Instructions:
- Mix Dry Ingredients: In a microwave-safe mug, combine flour, cocoa powder, sugar, and baking powder. Stir well to ensure there are no lumps.
- Add Wet Ingredients: Pour in the milk, vegetable oil or melted butter, and vanilla extract. Mix until the batter is smooth and well combined.
- Incorporate Peanut Butter: Drop a tablespoon of creamy peanut butter into the center of the batter. For an extra chocolatey experience, sprinkle in some chocolate chips.
- Microwave: Cook the mug in the microwave on high for about 1 minute. Microwave times may vary, so if the cake isn’t set, continue to cook in 10-second intervals.
- Enhance the Experience: Let the cake cool for a minute before digging in. For added flair, top with a drizzle of melted peanut butter, a dusting of powdered sugar, or a scoop of vanilla ice cream.

Tips for the Perfect Mug Cake
- Choose the Right Mug: Use a microwave-safe mug that holds at least 12 ounces to prevent overflow.
- Mix Thoroughly: Ensure all ingredients are well combined to avoid pockets of dry flour.
- Monitor Cooking Time: Microwaves vary in power; start with 1 minute and add more time as needed to avoid overcooking.
- Customize Your Cake: Add a pinch of salt to balance sweetness, or mix in chocolate chips for extra indulgence.
