Ingredients

Instructions

  1. Step 1: In a large microwave-safe mug, whisk together 4 tbsp all-purpose flour, 4 tbsp granulated sugar, 2 tbsp unsweetened cocoa powder, 1/4 tsp baking powder, 1/8 tsp chili powder, and a pinch of salt until evenly combined.
  2. Step 2: Add 3 tbsp whole milk, 2 tbsp vegetable oil, and 1/4 tsp vanilla extract to the dry ingredients. Stir well until the batter is smooth and no lumps remain.
  3. Step 3: Microwave the mug on high for 90 seconds. The cake should rise and be set but moist; if undercooked, microwave an additional 10-15 seconds carefully.
  4. Step 4: Meanwhile, in a chilled bowl, whip 1/4 cup heavy cream with 1 tbsp powdered sugar using a hand mixer on high speed until soft peaks form.
  5. Step 5: Spoon the whipped cream over the warm mug cake and serve immediately for a cozy single-serving dessert.
