Why you’ll love it (benefits)
- Very fast: ready in about 5 minutes from start to finish.
- Few ingredients: only three items, no butter, oil, or milk.
- Single-serve: you make just enough for one, so no waste.
- Easy and forgiving: simple to mix and quick to eat warm.
- Healthy-ish: uses a banana and eggs, so it has natural sweetness and protein.
Ingredients
- 1 ripe banana
- 2 eggs
- 1 teaspoon baking powder
Substitutions & key variations
- Banana: use a very ripe banana for best sweetness. For less banana flavor, use half a banana and add 1 tablespoon sugar or honey.
- Eggs: for an egg-free version, try 2 tablespoons chia seeds mixed with 6 tablespoons water (let sit 5 minutes) — results change.
- Baking powder: if you do not have baking powder, add 1/2 teaspoon baking soda plus 1 teaspoon lemon juice or vinegar.
- Add-ins: stir in a teaspoon of cocoa for a chocolate cake, a pinch of cinnamon, a drop of vanilla, or a few chocolate chips.
Step-by-step
Step 1 — Prep the banana
Peel and place the ripe banana in a small bowl or a large microwave-safe mug. Mash until smooth with a fork.
Step 2 — Mix eggs and baking powder
Crack the two eggs into the mashed banana. Add the teaspoon of baking powder. Stir well until the mix is smooth and even.
Step 3 — Cook
Pour or smooth the batter inside the mug so it is even. Microwave on high for 2 minutes. Check the cake: it should be set on top and spring back lightly when touched. If it is still wet, microwave in 10–15 second bursts until done.
Step 4 — Cool and enjoy
Let the cake cool for about 1 minute so it firms up. Eat straight from the mug or turn out onto a plate.

Success tips (temperature, texture, common mistakes)
- Use a very ripe banana for natural sweetness and softer texture.
- Mix well: mash the banana smooth and whisk until no big lumps remain.
- Microwave power varies: 2 minutes is for most microwaves. Shorten or lengthen in 10–15 second steps if needed.
- Avoid overcooking: the cake will dry out if microwaved too long. Stop when the center is firm but slightly springy.
- Choose the right mug: use a mug with room at the top so the cake can rise a bit without overflowing.
How to serve
- Serve warm from the mug with a spoon.
- Top with a spoonful of yogurt, a drizzle of honey, peanut butter, or a few fresh berries.
- A dusting of cinnamon or cocoa powder makes a nice finish.
- For a treat, add a few chocolate chips before cooking and they will melt on top.
Storage & reheating
- Store: keep any leftover cake in an airtight container in the refrigerator for up to 2 days.
- Freeze: you can freeze small pieces in a sealed bag for up to 1 month. Thaw in the fridge.
- Reheat: microwave for 15–30 seconds covered with a damp paper towel to warm without drying.
Frequently Asked Questions

A: Not as written. You can try replacing eggs with chia or flax “eggs” (2 tbsp chia or flax + 6 tbsp water) but texture will change.
Q: Can I double the recipe for two people?
A: Yes. Mix two bananas, four eggs, and 2 teaspoons baking powder. Cook in two mugs or a larger dish and increase microwave time slightly.
