How to Make Weight Watchers Zero Point Chocolate Mug Cake
This cake is fast, simple, and only needs one mug to make. All ingredients go into the same mug and cook in under two minutes.
Step 1: Mash the Banana
In your microwave-safe mug, mash ½ a medium ripe banana with a fork until smooth and creamy. The riper the banana, the sweeter your cake will be.
Step 2: Mix in Wet Ingredients
Add 1 large egg, 2 tablespoons of plain non-fat Greek yogurt, and ¼ teaspoon of vanilla extract (if using).
Stir everything until well combined.
Step 3: Add Dry Ingredients
Mix in 1 tablespoon of unsweetened cocoa powder, ¼ teaspoon of baking powder, and a pinch of cinnamon.
Stir thoroughly to create a smooth, lump-free batter.
Step 4: Microwave the Cake
Microwave the mug on high for 1 minute and 30 seconds. The cake should rise and set. If the top is still wet, microwave in 10-second bursts until cooked through. Don’t overcook!
Step 5: Cool and Serve
Let the cake rest for 30 seconds before eating. It will continue to set as it cools and become perfectly tender.
Serving and Decoration Tips
- Top with sliced banana or strawberries for natural sweetness.
- Dust with extra cocoa powder or cinnamon for garnish.
- A small dollop of zero-point Greek yogurt or a light sprinkle of unsweetened coconut can add texture and creaminess.
- For a fancy feel, serve in a glass cup and layer with fruit.
Variations to Try
Banana-Chocolate Chip Mug Cake
Add 1 tsp of sugar-free chocolate chips to the batter before microwaving. Gently fold them in. This adds a melty center and chocolate bursts without adding points if using WW-friendly chips.
Mint-Chocolate Mug Cake
Add 2–3 drops of mint extract instead of vanilla. This gives the cake a fresh twist, similar to mint chocolate desserts.
Mocha Mug Cake
Stir in ½ tsp of instant coffee powder with the cocoa powder. The coffee enhances the chocolate flavor, giving the cake a deep, rich taste.
For each variation, follow the same basic recipe and simply add or replace the mentioned ingredients. Cooking time remains the same.
Storing Tips
- Fresh is Best: This cake is best enjoyed right after cooking.
- Short-Term Storage: You can cover the mug and refrigerate for up to 1 day. Reheat in the microwave for 15–20 seconds.
- Do Not Freeze: The texture doesn’t hold well after freezing due to the banana and yogurt content.
To retain moisture when reheating, cover with a damp paper towel.
Common Mistakes, Solutions & Prevention
