Homemade puree may alter the final texture and baking time if it contains more water.What is the purpose of buttermilk in this recipe?Buttermilk reacts with the baking soda to leaven the cake, contributing to a tender crumb.Why did my crumb topping sink into the batter?This can occur if the batter is too thin or if the crumb topping is applied with too much pressure. Gently sprinkling the topping helps prevent this.You Must KnowProperly measuring the flour is critical. The spoon-and-level method is recommended: spoon the flour into the measuring cup and level it off with a knife. Do not scoop the cup directly into the flour bag, as this leads to over-measuring and a dense cake. Ensure all ingredients, particularly the eggs and buttermilk, are at room temperature for proper emulsion and a uniform batter.Storage TipsStore the completely cooled cake covered at room temperature for up to two days. For longer storage, wrap tightly and refrigerate for up to five days. The cake can be frozen for up to three months; thaw overnight in the refrigerator before serving.
