If you love chocolate but want something quick, easy, and a bit healthier, this 5-minute microwave chocolate chip mug cake is a total game changer. It’s perfect for breakfast, a snack, or whenever you need a little chocolate fix without any fuss. With just six simple ingredients — all wholesome and naturally sweetened — it comes together in minutes and tastes like a treat you can feel good about.
No need to heat up the oven or pull out a mixing bowl; just grab a mug, mash your banana, and you’re almost there. The oats add fibre and keep you fuller for longer, while the almond butter adds a subtle nuttiness and a hit of protein. Dark chocolate chips give that rich chocolatey burst, but without overloading on sugar.
I love this recipe because it feels indulgent but is actually nourishing and super satisfying. Plus, it’s a perfect solo portion, so you don’t have leftovers tempting you! Whether you’re rushing out the door or settling down with a cosy cuppa, this mug cake has got you covered.
Tips
- Mashing the banana: Mash the banana really well to avoid lumps and ensure the cake texture is smooth.
- Microwave power: Microwave times may vary depending on your microwave wattage. Start with 1 minute and add 30-second bursts to avoid overcooking.
- Prevent overflow: Wipe the edges of the mug before microwaving to prevent batter from bubbling over.
- Texture preference: For a softer cake, reduce the oats slightly; for a denser, more filling cake, add a little more oats.
- Serving: Enjoy straight from the mug or tip out onto a plate for a more traditional cake feel.
Swaps
Oats: Ground almond should work too but it will have a different texture and flavour.
Banana: Swap with unsweetened applesauce for a different flavour and texture.
Almond butter: Try peanut butter, cashew butter, or sunflower seed butter for a nut-free option.
Chocolate chips: Use chopped dark chocolate, cacao nibs, or dried fruit pieces like raisins or chopped dates.
Egg: Use 1 tbsp of ground flaxseed mixed with 3 tbsp water (let sit 5 minutes) for a vegan alternative.
Storage
Fridge: Store for up to 3 days in the mug or transferred to a sealed container. Reheat gently in the microwave or enjoy cold—it becomes more pudding-like in texture.
Freezer: Not ideal for freezing once cooked, but you can freeze the blended mix (before cooking) in a small container. Defrost overnight and microwave when ready.
