Ingredients

Scale

Dry Ingredients

2 tablespoons all-purpose flour
1/4 teaspoon baking powder

Wet Ingredients

2 tablespoons creamy peanut butter
2 tablespoons unsweetened almond milk
1 tablespoon pure maple syrup
1/2 teaspoon pure vanilla extract (optional)

Add-ins

1 tablespoon dairy-free chocolate chunks (optional)

Instructions

Mix Ingredients: Add all ingredients except the chocolate chunks (if using) into an 8-ounce or larger microwave-safe mug. Stir thoroughly with a fork until the batter is smooth and combined. If the batter is too thick and clings to the spoon, add a splash of almond milk to thin it just enough so it stays in the mug.
Microwave Cooking: Microwave the mug on high power for 45-60 seconds, or until the cake has risen and springs back slightly when poked. Check at 30 seconds if your microwave cooks quickly. If needed, cook in additional 15-second intervals but avoid overcooking to prevent dryness.
Oven Baking (Alternative): Preheat oven to 375°F (190°C). Pour the batter into an oven-safe ramekin or mug and bake for 15-20 minutes until the cake is domed and springs back when pressed.
Add Toppings and Serve: Top the warm cake with the optional dairy-free chocolate chunks if desired. Enjoy immediately straight from the mug for a cozy treat.

Notes

Use a microwave-safe mug that can hold at least 8 ounces to prevent overflow during cooking.
If you prefer sweeter cake, increase maple syrup by 1 teaspoon.
For a nut-free variation, substitute peanut butter with sunflower seed butter.
Ensure not to overcook as the cake can dry out and become crumbly.
Try adding a pinch of cinnamon or a handful of chopped nuts for extra flavor and texture.
