Ingredients
- 1 cup all-purpose flour
- 1 cup granulated sugar
- ½ cup unsalted butter, melted
- 2 large eggs
- ½ cup milk
- 1 teaspoon vanilla extract
- 1 ½ teaspoons baking powder
- ¼ teaspoon salt
- Optional: cocoa powder for chocolate version or zest for a citrus twist
Instructions
Step 1: Preheat and prepare the pan
Preheat your oven to 350°F (175°C). Grease and line an 8-inch round or square cake pan with parchment paper to ensure easy removal.
Step 2: Mix the wet ingredients
In a large mixing bowl, whisk together melted butter, eggs, milk, and vanilla extract until smooth and creamy.
Step 3: Combine the dry ingredients
In another bowl, mix the flour, sugar, baking powder, and salt. For a chocolate version, add 2–3 tablespoons of cocoa powder.
Step 4: Combine wet and dry ingredients
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Avoid overmixing to keep the cake light and airy.
Step 5: Bake the cake
Pour the batter into the prepared pan and smooth the top. Bake in the preheated oven for 12–15 minutes, or until a toothpick inserted into the center comes out clean.
Step 6: Cool and serve
Allow the cake to cool in the pan for 5 minutes, then transfer to a wire rack. Serve plain, dusted with powdered sugar, or topped with frosting, whipped cream, or fresh fruit.
Tips for Perfect 15-Minute Cake
- Use room-temperature eggs and milk: This helps the batter combine more evenly and improves texture.
- Don’t overmix: Overmixing can make the cake dense. Stir until ingredients are just combined.
- Check for doneness early: Every oven is different; start checking at 12 minutes to avoid overbaking.
- Add flavor variations: Mix in chocolate chips, nuts, or citrus zest to make it unique.
- Single-serve option: Pour batter into muffin tins for quick, individual mini-cakes.
