Description
This healthy banana oat mug cake is tender, light, and fluffy. It’s quick and easy to prepare, making it a great snack, breakfast, or dessert.
Ingredients
- 1/2 extra ripe banana (70 g, about 1/4 cup mashed banana)
- 1 tablespoon natural peanut butter
- 1 tablespoon coconut sugar
- 1/4 teaspoon vanilla extract
- Pinch of sea salt
- 1 tablespoon water (or milk of choice)
- 1/4 cup oat flour (35 g), gluten-free if necessary
- 1/2 teaspoon baking powder
- 1 tablespoon chocolate chips (optional)
- 1 tablespoon chopped walnuts (optional)
Instructions
- In a small bowl, mash the half of the banana until smooth.
- Add in the peanut butter, coconut sugar, vanilla extract, sea salt, and water, and whisk until well combined.
- Next, stir in oat flour and baking powder and mix until well combined. The batter should be thick enough to stir but not too runny. If it feels too thick, add 1-2 teaspoons of water until you reach the desired consistency (you can refer to the video for guidance). For extra flavor and texture, fold in some chocolate chips and chopped walnuts, if desired.
- Pour the batter into a wide-mouthed microwave-safe mug (mine has 10 oz / 300 ml). Sprinkle a few more chocolate chips onto the batter, if desired.
- Place the mug in the microwave and microwave on high for about 1 minute and 10 seconds. The cooking time may vary depending on the wattage of your microwave. The cake should be fully cooked around the edges and slightly pulled away from the mug, with a center that appears a bit underdone (but the batter on top should no longer be wet). As the cake cools, it will continue to cook slightly, so be careful not to overcook it. If the cake needs more time, cook it in additional 10-second increments until it reaches the desired level of doneness. For my 950 W microwave, I find that 1 minute and 30 seconds is the perfect amount of time. Don’t overcook the cake, or it may become tough.
- Remove the mug from the microwave and let cool for 2-3 minutes before enjoying. The cake will finish cooking slightly during the resting time.
Notes
While you can mix the ingredients directly in the mug, I suggest using a separate bowl to prepare the batter. This allows for better mashing of the banana and easier mixing of the other ingredients with more room to work.
For best results, choose a microwave-safe mug with a wide opening and a capacity of at least 10 oz (300 ml). The cake will rise as it cooks, so it’s important to use a mug that’s spacious enough to accommodate this expansion.
It’s important not to overcook your mug cake, as this can result in a dry, rubbery texture. It’s better to slightly undercook it, as the cake will continue to cook slightly as it rests. If you do accidentally overcook it, add 2 teaspoons of water or milk of choice on top, and it will help moisten it back up.
