Ingredients
- 4 tbsp all-purpose flour
- 4 tbsp granulated sugar
- 2 tbsp unsweetened cocoa powder
- 1/4 tsp baking powder
- 3 tbsp milk
- 2 tbsp vegetable oil
- 1/4 tsp vanilla extract
- 1 piece (about 10g) soft caramel candy
Instructions
- Step 1: In a microwave-safe mug (12 oz capacity), whisk together 4 tablespoons all-purpose flour, 4 tablespoons granulated sugar, 2 tablespoons unsweetened cocoa powder, and 1/4 teaspoon baking powder until combined.
- Step 2: Add 3 tablespoons milk, 2 tablespoons vegetable oil, and 1/4 teaspoon vanilla extract to the dry ingredients in the mug. Stir thoroughly until a smooth batter forms without lumps.
- Step 3: Push 1 soft caramel candy piece into the center of the batter, slightly submerging it but leaving the top visible.
- Step 4: Microwave on high power for 70-80 seconds. Start checking at 70 seconds by gently touching the cake top; it should be set but still soft in the center.
- Step 5: Let the mug cake rest for 1 minute to allow the molten caramel to settle and cool slightly.
- Step 6: Enjoy warm directly from the mug with a spoon, savoring the rich chocolate cake and gooey caramel core.
