Description

A cozy, melty peanut butter banana mug cake made in minutes with just a handful of ingredients. Perfect for late-night cravings or quick breakfasts, this gluten-free treat is soft, gooey, and naturally sweet.


Ingredients

Scale

1 ripe banana

1 egg

1 tbsp unsweetened vanilla almond milk (or regular milk + splash of vanilla extract)

Splash of maple syrup (optional)

1 tbsp peanut butter

3 tbsp gluten free all purpose flour

Pinch of sea salt

1 tbsp chocolate chips or chopped dark chocolate


Instructions

1. In a large microwave-safe mug, mash the banana until smooth.

2. Add the egg, almond milk, and maple syrup (if using), and whisk until well combined.

3. Stir in the peanut butter until smooth.

4. Add the flour, sea salt, and chocolate chips. Stir until fully mixed.

5. Microwave on high for 2 minutes. Pause at 90 seconds to prevent overflow, if needed.

6. Let cool for 1–2 minutes. Enjoy warm with a spoon!


Notes

Use an overripe banana for best flavor and texture.

Adjust cook time based on microwave strength.

Make it dairy-free using almond or oat milk.

For a richer version, add a teaspoon of cocoa powder.
