Ingredients
- 1/4 cup all-purpose flour
- 2 tablespoons unsweetened cocoa powder
- 1/4 teaspoon baking powder
- 2 tablespoons granulated sugar (add 1 tablespoon more if you like it sweeter)
- 1/8 teaspoon kosher salt
- 1/4 cup + 1 tablespoon milk
- 2 tablespoons vegetable oil
- 1 tablespoon hazelnut chocolate spread or mini chocolate chips
Instructions
- Step 1: In a medium bowl, whisk together the flour, cocoa powder, baking powder, sugar, and salt until well combined.
- Step 2: Add the milk and vegetable oil to the dry ingredients, then whisk until the batter is smooth and free of clumps.
- Step 3: Pour the batter into a microwave-safe mug (about 14 ounces), leaving enough room for the cake to rise without overflowing.
- Step 4: Drop the hazelnut chocolate spread or mini chocolate chips into the center of the batter. No need to push it down, it will sink naturally as it cooks.
- Step 5: Place a paper towel in the microwave and set the mug on top to catch any potential overflow.
- Step 6: Microwave on high for 70 seconds. Watch carefully as microwaves vary; adjust time slightly if needed.

- Top with whipped cream or a scoop of vanilla ice cream for an extra special touch.

FAQs
Can I use a different type of flour?
All-purpose flour works best for the right texture, but you can try whole wheat flour; just note that the cake will be denser and the taste a bit different.
What if my mug cake overflows in the microwave?
Make sure to use a mug with at least 14 ounces capacity to allow enough rise space. Placing a paper towel beneath helps catch drips, and shortening the cook time slightly can prevent overflow as well.
