Ingredients
Method
- Preheat your oven to 350°F (175°C). Grease a 9-inch square cake pan with butter or nonstick spray, then dust lightly with flour.
- In a large mixing bowl, beat together the softened butter and sugar using an electric mixer on medium speed until light and fluffy (about 2–3 minutes).
- Add eggs one at a time, beating after each addition until incorporated. Stir in the vanilla extract.
- In a separate bowl, whisk together the flour and baking powder until evenly combined.
- Add the flour mixture to the wet ingredients in three parts, alternating with milk. Begin and end with the flour, mixing just until smooth each time. Do not overmix.
- Pour the batter into the prepared pan and spread it evenly. Tap the pan lightly on the counter to release air bubbles.
- Bake in the center of the oven for 30–40 minutes, or until a toothpick inserted in the center comes out clean. The top should be golden and springy.
- Let the cake cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing or frosting.
Notes
Swap milk with buttermilk or sour cream for a tangy flavor boost. Add zest or spices for a twist. Store in an airtight container at room temperature for up to 3 days, or freeze slices for longer shelf life.
