This guide explains the common causes of cakes sinking in the middle and provides easy fixes to achieve a perfectly risen, tender, and fluffy cake every time.

Ingredients

  • All-purpose flour (about 1 cup or 120 grams per cup)
  • Baking powder or baking soda (fresh)
  • Granulated sugar or brown sugar
  • Unsalted butter, softened to room temperature
  • Large eggs, at room temperature
  • Milk or buttermilk
  • Vanilla extract
  • Salt (a pinch)
  • Optional: Almond flour or coconut flour for gluten-free options
  • Optional: Yogurt or sour cream as a milk substitute

Instructions

  1. Preheat the oven to 350°F (175°C) using an oven thermometer to confirm the temperature. Preheating takes about 10-15 minutes.
  2. Grease an 8- or 9-inch round baking pan with butter or non-stick spray, then lightly flour it or line it with parchment paper.
  3. Sift together the flour, baking powder, and salt in a bowl to distribute the leavening agents evenly. Set aside.
  4. In a separate bowl, cream the softened butter and sugar together until light and fluffy, about 3-5 minutes with an electric mixer.
  5. Beat in eggs one at a time, mixing well after each addition to ensure proper emulsification.
  6. Stir in vanilla extract or other flavorings.
  7. Alternate adding the flour mixture and milk in three parts, starting and ending with the flour. Mix gently after each addition to avoid overmixing.
  8. Pour the batter into the prepared pan, filling it about 2/3 full. Smooth the top with a spatula.
  9. Bake on the middle rack for 30-40 minutes or until a toothpick inserted comes out clean. Avoid opening the oven door during baking.
  10. Let the cake cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely. Avoid cooling upside down or on the side.

Notes

Use fresh baking powder or baking soda to ensure proper rise. Avoid overmixing the batter to prevent gluten development which causes sinking. Preheat the oven fully before baking and avoid opening the oven door during baking. Cool the cake properly to prevent collapse. For gluten-free versions, use almond or oat flour with xanthan gum. For vegan adaptations, replace eggs with flax eggs and use plant-based milk and butter.
