Ingredients

1 large egg
1 tablespoon unsweetened cocoa powder
1 packet zero-calorie sweetener (stevia or Splenda)
½ teaspoon vanilla extract (optional)
Pinch of salt (optional)

Instructions
Prepare the Batter
In a microwave-safe mug, mash the banana until smooth and lump-free.
Add the egg and whisk well until fully combined.
Stir in cocoa powder, sweetener, vanilla extract, and a pinch of salt.
Mix until the batter is smooth and evenly blended.
Cook the Mug Cake
Microwave on high for 60 to 90 seconds.
Check doneness; the cake should be set but still soft and slightly moist in the center.
Avoid overcooking to prevent dryness.
Serve
Let the mug cake cool for 1–2 minutes before eating.
Enjoy directly from the mug or turn it out onto a plate if preferred.
Tips
Use a very ripe banana for natural sweetness and smoother texture.
Mash banana thoroughly to avoid lumps in the final cake.
Do not overcook; microwave times vary and overcooking makes it rubbery.
Mix ingredients well to ensure even cocoa distribution.
Use a wide mug to prevent overflow during cooking.
Add cocoa gradually for better blending.
Let the cake rest after microwaving to finish setting.
For richer flavor, add a few sugar-free chocolate chips before cooking.
If using Greek yogurt, whisk extra well for smooth consistency.
Adjust sweetness based on personal preference since bananas vary in sweetness.
Variations
Add sugar-free chocolate chips for extra chocolate bursts.
Mix in a teaspoon of peanut butter for a chocolate-peanut swirl.
Add cinnamon or espresso powder for deeper flavor.
Top with whipped coconut cream for a dairy-free option.
Use pumpkin puree for a fall-inspired mug cake.
Add chopped nuts for texture and crunch.
Mix in berries for a fruity chocolate combination.
Use almond extract instead of vanilla for a nutty aroma.
Add a spoon of protein powder for a high-protein version.
Top with light Greek yogurt for a cheesecake-style twist.
