Ingredients Explained
For a perfect mug cake, each ingredient plays an important role:
1 ripe banana: Adds natural sweetness and moisture. The riper the banana, the sweeter and softer the cake.
1 large egg: Provides structure and helps the cake rise.
2–3 tbsp sugar: Adjust according to sweetness preference. Can substitute with honey or maple syrup.
2 tbsp cocoa powder: Gives rich chocolate flavor. Use unsweetened cocoa for the best taste.
2 tbsp oil or melted butter: Keeps the cake soft and moist. Butter adds richness, while oil keeps it tender.
2 tbsp milk: Helps create a smooth batter. Can use dairy or plant-based milk.
¼ tsp baking powder: Ensures the cake rises slightly for a fluffy texture.
½ tsp vanilla extract: Enhances overall flavor.
Pinch of salt: Balances sweetness and enhances chocolate flavor.
Optional toppings: chocolate chips, chopped nuts, banana slices, or a drizzle of caramel or chocolate sauce.
Step-by-Step Method
Step 1: Mash the Banana
Mash the ripe banana in a microwave-safe mug using a fork. Small lumps are okay, but large chunks may affect the texture. Bananas give natural sweetness and moisture, eliminating the need for extra sugar.
Tip: Use a fork to mash the banana thoroughly to create a smooth base.
Step 2: Add Wet Ingredients
Add the egg, milk, oil (or melted butter), and vanilla extract to the mashed banana. Mix thoroughly until smooth.
Tip: Whisk gently; overmixing can make the cake dense.
Step 3: Add Dry Ingredients
Sprinkle sugar, cocoa powder, baking powder, and a pinch of salt into the mug. Stir gently until all ingredients are fully combined.
Optional: Fold in chocolate chips, chopped nuts, or a tablespoon of peanut butter for extra richness.
Tip: Do not overmix — a smooth batter with a few tiny air pockets ensures a soft texture.
Step 4: Microwave Cooking
Cook in the microwave on high for 1–2 minutes, depending on the microwave’s power. Start with 60 seconds, then check and add 10–15 second bursts until the cake rises and is set but still soft in the center.
Tip: Overcooking will dry the cake. Microwaves vary, so adjust carefully.
Variations You Can Try
Nutty Banana Chocolate Mug Cake: Add 1 tbsp chopped walnuts or almonds.
Peanut Butter Twist: Swirl 1 tbsp peanut butter into the batter before microwaving.
Vegan Option: Replace the egg with 2 tbsp of applesauce or a flaxseed egg (1 tbsp flaxseed + 3 tbsp water).
Extra Chocolate: Sprinkle cocoa powder or chocolate chips on top before microwaving.
Coffee Chocolate: Add ¼ tsp instant coffee powder for a mocha flavor.
