Peanut Butter Mug Cake Recipe

Introduction

This Peanut Butter Mug Cake is a quick and delicious treat that you can make in just a few minutes using your microwave. Perfect for satisfying a sweet tooth without any fuss, it combines rich peanut butter flavor with a soft, fluffy texture.

Ingredients

• 1 & 1/2 tbsp butter (melted)
• 1 & 1/2 tbsp peanut butter
• 1 egg yolk
• 2 tbsp brown sugar
• 1 & 1/2 tbsp milk
• 1/8 tsp vanilla extract (optional)
• 2 tbsp flour
• 1/8 tsp baking powder
• a pinch of salt
• vanilla frosting (optional)

Instructions

1. Step 1: Melt the butter directly in a microwave-safe mug. Add the peanut butter and stir until fully combined. Then add the egg yolk, brown sugar, salt, milk, and vanilla extract if using. Mix well.
2. Step 2: Add the flour and baking powder to the mug, stirring thoroughly until the batter is smooth and free of lumps.
3. Step 3: Microwave the mug on high power for 60 seconds. The cake should rise and set during this time. Let it cool slightly before topping with vanilla frosting or crushed peanuts if desired. Enjoy warm.

Tips & Variations

• For a fluffier texture, try adding a pinch more baking powder or a drop of vinegar to react with the baking soda.
• Swap brown sugar for honey or maple syrup for a different sweetness profile.
• Add chocolate chips or a sprinkle of cinnamon for extra flavor.
• If you don’t have vanilla frosting, a dollop of whipped cream pairs nicely.

Storage

This mug cake is best enjoyed fresh, but if needed, store leftovers covered in the refrigerator for up to 2 days. Reheat briefly in the microwave to soften before eating.

FAQs

Can I use a whole egg instead of just the yolk?

Using a whole egg may change the texture slightly, making it less rich but still tasty. If you do, reduce the milk by a teaspoon to keep the batter balanced.

What type of peanut butter works best?

Natural creamy peanut butter works well for a smooth texture, but you can use crunchy peanut butter for added crunch and flavor.
