Craving a rich and indulgent dessert thatβs keto-friendly? This Keto Chocolate Banana Cake is a quick fix for your sweet tooth. Made with almond flour, monk fruit sweetener, and ripe banana, itβs ready in minutes and topped with creamy peanut butter for an extra treat!
π΄ Ingredients:

- 1/2 cup almond flour
- 2 tablespoons unsweetened cocoa powder
- 2 tablespoons monk fruit sweetener (adjust to taste)
- 1 medium ripe banana, mashed
- 1 large egg
- A pinch of salt
- Chocolate chips – optional
π§βπ³ Instructions:
- Mix the Wet Ingredients:
In a microwave-safe mug or small bowl, mash the banana until smooth. Add the egg and whisk until well combined. - Add the Dry Ingredients:
Stir in almond flour, cocoa powder, monk fruit sweetener, and a pinch of salt. Mix thoroughly until the batter is smooth. - Microwave the Cake:
Microwave on high for 90 seconds to 2 minutes, depending on the power of your microwave. Start with 90 seconds and check; if the cake still looks wet in the center, microwave in 10-second intervals until it sets. - Toothpick Test for Doneness:
Insert a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs, the cake is ready. - Cool and Add Toppings:
Let the cake cool for 1-2 minutes. Top with a dollop of creamy peanut butter, a sprinkle of chopped nuts, or sugar-free chocolate chips for extra indulgence. - Serve and Enjoy:
Enjoy straight from the mug, or gently loosen the edges with a knife and invert it onto a plate.
π° Tips for Perfect Results:
- Microwave Power: Microwaves vary in power, so start with a shorter time and adjust as needed. Overcooking can make the cake dry.
- Topping Ideas: Peanut butter pairs perfectly, but you can also use sugar-free whipped cream, fresh berries, or a drizzle of melted sugar-free chocolate.
- Sweetness Adjustment: Adjust the amount of monk fruit sweetener to suit your taste.
