How to Make Chocolate Mug Cake with Chocolate Syrup
Step 1: Combine Dry Ingredients
In a microwave-safe mug, mix together:
- 4 tablespoons all-purpose flour
- 2 tablespoons cocoa powder
- 2 tablespoons sugar
- ¼ teaspoon baking powder
- A pinch of salt
Stir until all dry ingredients are well combined.
Step 2: Add Wet Ingredients
Add the following directly into the mug:
- 3 tablespoons milk
- 1 tablespoon vegetable oil
- ⅛ teaspoon vanilla extract (optional)
Mix until the batter is smooth and even.
Step 3: Add Chocolate Syrup
- Add 1 tablespoon chocolate syrup and gently swirl it into the batter.
- For a molten center, add another tablespoon in the middle and leave it as-is.
Step 4: Microwave
Microwave the mug on high for 90 seconds.
If it still looks undercooked, heat in 10-second intervals, checking each time.
Let the cake sit for 1 minute before eating to settle and cool slightly.
Serving and Decoration Tips
- Drizzle additional chocolate syrup on top while it’s still warm.
- Dust with powdered sugar or cocoa powder for a café-style finish.
- Add a scoop of vanilla or chocolate ice cream.
- Top with mini marshmallows or crushed nuts for added texture.
- You can also serve with whipped cream and berries for a balanced look and taste.
Variations to Try
Molten Lava Version
- After pouring the batter into the mug, press a small square of chocolate or a spoonful of chocolate syrup into the center.
- Do not mix. Microwave as usual. This creates a soft, gooey center.
Nutella Chocolate Cake
- Add 1 tablespoon of Nutella along with the chocolate syrup.
- Swirl it gently into the batter and microwave as usual.
Mocha Version
- Stir in ½ teaspoon of instant coffee granules with the dry ingredients.
- This adds a subtle espresso flavor that complements the chocolate beautifully.
Peanut Butter Swirl
- Drop a teaspoon of peanut butter on top before microwaving.
- It adds a nutty, creamy twist to the final bite.
Storing Tips
- Best enjoyed immediately for the best texture and warmth.
- If needed, cover the mug and store in the refrigerator for up to 2 days.
- To reheat, microwave for 20–30 seconds.
- If dry, drizzle fresh chocolate syrup before eating.
- Avoid freezing, as the texture may not hold up well after thawing.
Common Mistakes and Fixes
