Ingredients

For the Mug Cake:

4 tablespoons all-purpose flour

4 tablespoons sugar

1/8 teaspoon baking powder

1/8 teaspoon salt

3 tablespoons milk (or plant-based milk)

2 tablespoons peanut butter

1 tablespoon vegetable oil (or melted coconut oil)

1/2 teaspoon vanilla extract

Optional Toppings:

Whipped cream

Chocolate chips

Sliced bananas

Ice cream

Crushed peanuts

Chocolate syrup or caramel sauce

Instructions

Mix Dry Ingredients:

In a microwave-safe mug, combine flour, sugar, baking powder, and salt. Stir well to ensure everything is evenly distributed.

Add Wet Ingredients:

Into the same mug, add the milk, peanut butter, vegetable oil, and vanilla extract. Stir until you achieve a smooth, lump-free batter.

Microwave:

Microwave on high for 1 minute and 30 seconds. Cooking times may vary depending on your microwave’s wattage, so keep an eye on the cake. The cake should look set and firm to the touch.

Cool and Enjoy:

Let the mug cake cool for a minute before diving in. Enjoy it warm, straight from the mug!

Notes

Peanut Butter Texture: Smooth peanut butter works best for an even batter, but you can use crunchy peanut butter if you prefer a bit more texture.

Flour Substitutes: If you need a gluten-free version, you can use almond flour or a gluten-free all-purpose flour blend.

Sweetness Adjustment: Adjust the sugar to your taste. If you like a sweeter cake, add an extra tablespoon of sugar.

Vegan Option: Use plant-based milk, vegan-friendly peanut butter, and a plant-based oil to make this mug cake vegan.
