Ingredients

Gather these simple ingredients to make your Peanut Butter Mug Cake:

For the Mug Cake:

  • 3 tablespoons peanut butter (creamy or chunky)
  • 1 tablespoon butter, melted
  • 1/4 cup milk (dairy or non-dairy)
  • 1/4 cup all-purpose flour
  • 1/4 teaspoon baking powder
  • 1 tablespoon brown sugar (or granulated sugar)
  • 1/4 teaspoon vanilla extract
  • A pinch of salt

Ingredient Highlights

  • Peanut Butter: The star of this dessert, giving the cake its nutty, rich flavor.
  • Butter: Adds a rich, creamy texture to the cake batter.
  • Milk: Helps bring the batter together for a smooth consistency.
  • Flour: The base of the mug cake, giving it structure and fluffiness.
  • Baking Powder: Ensures the cake rises to perfection, creating that soft and fluffy texture.

Step-by-Step Instructions

Follow these easy steps to make your Peanut Butter Mug Cake:

Prepare the Mug Cake

  1. Combine Wet Ingredients: In a microwave-safe mug, add the peanut butter, melted butter, milk, and vanilla extract. Stir until smooth and well combined.
  2. Mix Dry Ingredients: Add the flour, baking powder, brown sugar, and salt to the mug. Mix until all the ingredients are fully incorporated, and the batter is smooth.
  3. Microwave: Microwave the mug on high for 1 minute and 30 seconds to 2 minutes, depending on the strength of your microwave. Keep an eye on the cake while it cooks—if it overflows, stop the microwave and let it settle before continuing.
  4. Check for Doneness: The mug cake should rise and firm up, but still have a soft, gooey center. If the top is set, it’s done!

Serve and Enjoy

  1. Let It Cool: Allow the mug cake to cool for about 1 minute before digging in—it will be very hot!
  2. Toppings (Optional): For an extra treat, top your mug cake with whipped cream, a drizzle of melted chocolate, a few chocolate chips, or a scoop of vanilla ice cream.

How to Serve

Here are some fun ways to enjoy your Peanut Butter Mug Cake:

  1. Top It Off: Add a dollop of whipped cream and a few chocolate chips for an indulgent dessert experience.
  2. Pair with Ice Cream: For a decadent treat, serve the mug cake with a scoop of vanilla or chocolate ice cream on top.
  3. Customize with Add-ins: Feel free to mix in some chocolate chips, chopped peanuts, or a drizzle of honey for added flavor and texture.
  4. Serve with a Drink: Pair it with a hot cup of coffee, milk, or a sweetened iced latte for a delightful treat.

Additional Tips

To get the most out of your Peanut Butter Mug Cake, keep these helpful tips in mind:

  1. Don’t Overcook: Microwave power levels vary, so check your cake after 1 minute and 30 seconds. If the cake is still undercooked, microwave for another 20–30 seconds.
  2. Adjust Sweetness: If you like your mug cake a bit sweeter, feel free to add a touch more sugar or even a spoonful of honey.
  3. Add-ins: Mix in some chocolate chips or swirl in a bit of Nutella before microwaving for extra indulgence.
  4. Use the Right Mug: Make sure you’re using a large enough mug to allow room for the cake to rise. A 12-ounce mug works perfectly.
  5. Don’t Skip the Salt: A pinch of salt really helps enhance the peanut butter flavor and balance the sweetness of the cake.
  6. Make It Dairy-Free: Swap the butter and milk for dairy-free versions to make this mug cake suitable for lactose-intolerant individuals.
  7. Serve Warm: Mug cakes are best enjoyed while still warm and gooey, so make sure to dig in right after cooking!

Recipe Variations

Experiment with these creative twists on the classic Peanut Butter Mug Cake:

  • Chocolate Peanut Butter Mug Cake: Add 2 tablespoons of cocoa powder or a handful of chocolate chips to the batter for a chocolate-peanut butter combo.
  • Peanut Butter Banana Mug Cake: Mash half a ripe banana into the batter for added moisture and flavor.
  • Peanut Butter and Jelly Mug Cake: After microwaving, top your mug cake with a spoonful of your favorite jelly or jam for a nostalgic flavor.
  • Gluten-Free Version: Swap the all-purpose flour for a gluten-free flour blend or almond flour for a gluten-free treat.
  • Nut-Free: Use sunflower seed butter or almond butter as a peanut butter alternative for a nut-free option.

Freezing and Storage

Although mug cakes are best served fresh, you can store or freeze them if necessary:

  • Storage: If you have leftovers (which is rare!), store the cooled mug cake in an airtight container at room temperature for up to 1 day.
  • Freezing: Freeze the cooled mug cake for up to 1 month. Reheat it in the microwave for 20–30 seconds when you’re ready to enjoy it again.
  • Reheating: Microwave the stored or frozen mug cake for 20-30 seconds to warm it up, ensuring it doesn’t dry out.

Special Equipment

All you need for this simple mug cake is:

  • Microwave-safe Mug: For mixing and cooking the cake.
  • Spoon: To stir the ingredients together.
  • Measuring Cups and Spoons: To accurately measure the ingredients.
