Key element — use a very ripe avocado
A soft, ripe avocado mashes completely smooth with no chunks and no green flavor. An underripe one leaves lumps you can taste.
Ingredients
Cake
- 1 medium very ripe avocado
- 1 large egg
- 3 Tbsp unsweetened cocoa powder
- 3 Tbsp powdered sugar-free sweetener
- ¼ cup chocolate protein powder
- 1 tsp vanilla extract
- ½ tsp baking powder
- Pinch of salt
Swaps
- Microwave: Cook 2 minutes instead of baking — slightly denser, still fudgy.
- No protein powder: Add 3 Tbsp more cocoa and 1 Tbsp more sweetener.
- Double batch: Double everything in two ramekins for a friend.
- Extra fudgy: Stir in 1 Tbsp sugar-free chocolate chips before baking.
Instructions
| 1 | Prep. Heat the oven to 350°F. Grease a large oven-safe ramekin. |
| 2 | Mash the avocado. Mash the ripe avocado in the ramekin until completely smooth — no lumps. |
| 3 | Add the egg. Whisk in the egg and vanilla until silky. |
| 4 | Add the dry. Stir in the cocoa, sweetener, protein powder, baking powder, and salt until you have a thick, glossy batter. |
| 5 | Bake. Bake 14–16 minutes until the top is set but the center still looks slightly soft. (Microwave option: 2 minutes.) |
| 6 | Cool and serve. Cool 5 minutes — it firms up as it cools. Serve warm with whipped cream or berries. |
Pro tips
- Blend the batter with a small whisk or fork — lumps of avocado survive baking.
- Don't overbake — a slightly soft center means fudgy, not dry.
- Taste the batter and add another spoonful of sweetener if your cocoa is bitter.
- A pinch of espresso powder deepens the chocolate flavor.
- Serve it warm — the texture is at its best fresh from the oven.
