Dessert

Peanut Butter Banana Mug Cake

Ninety seconds, one mug, one fork. It exists for the specific evening when you want cake and are not going to make a cake.

Peanut Butter Banana Mug Cake — ingredients and quantities for 1 serving
1 serving. Every quantity on this page is written out in full.

Mug cakes are usually dry, and the reason is nearly always time. Ninety seconds sounds too short and it is not; two and a half minutes turns it to rubber.

The banana does most of the work — moisture, sweetness and binding — so the flour quantity stays low.

Ingredients

1 serving
AmountIngredient
1very ripe banana, mashed
2 tbsppeanut butter
1egg
3 tbspflour
1/2 tspbaking powder
1 pinchsalt
1 tbspchocolate chips, optional

Method

  1. Mash the banana in a large mug with a fork until there are no lumps left.
  2. Peanut butter and egg in, and beat until it is one thing rather than three.
  3. Flour, baking powder and salt. Mix just until combined; overmixing makes it tough.
  4. Chocolate chips on top if using — they sink to about the middle.
  5. Microwave 80 to 100 seconds at full power. Stop when the top is set but still looks slightly damp.
  6. Wait a minute before eating it. It finishes cooking in the mug and it is molten hot.

Notes

  • A big mug. It rises much more than seems reasonable and then goes over the side.
  • The banana must be properly ripe. A yellow one gives you a bland, dense cake.
  • Microwaves vary enormously. Find your number once and write it down.

Questions

It came out rubbery.

Ten seconds too long. Try eighty seconds next time and add in five-second steps.

No egg?

Another half banana and a splash of milk. It will be denser and it will still work.
