Can I use frozen peaches for this coffee cake?

Yes, but they must be thawed completely and patted dry with a paper towel first. Frozen fruit releases significantly more moisture than fresh fruit, which can compromise the structural integrity of the crumb if not handled with precision.

How should I store the leftover cake to maintain its texture?

Wrap the cake tightly in plastic wrap and then in a layer of foil to prevent moisture loss. Store it in the refrigerator for up to one week, though the crust will naturally soften over time as the internal moisture migrates.

Why did my peaches sink to the bottom of the pan?

The peaches likely sank because they were either cut too large or the batter was over-mixed and became too thin. The 32 grams of flour added to the peach mixture is specifically designed to help the fruit grip the batter and stay suspended.

Can I substitute the vegetable oil with melted butter?

You can, but the texture will change significantly once the cake reaches room temperature. Butter contains water and solids that will firm up, whereas oil remains liquid, providing a superior mouthfeel and longer-lasting moisture in the crumb.

Is buttermilk essential or can I use regular milk?

Buttermilk is critical because its acidity reacts with the baking soda to create the necessary lift. If you must use regular milk, you will need to add a teaspoon of lemon juice to mimic the pH level required for the chemical leavening process.

What happens if I over-mix the batter after adding flour?

Over-mixing activates the gluten proteins in the flour, creating a tough and elastic network. This leads to a rubbery texture rather than the tender, melting crumb that defines a high-quality coffee cake.

Instructions

Prepare the pan. Preheat your oven to 175 degrees Celsius and coat a 9-inch springform pan with cooking spray.
Create the emulsion. Beat eggs, buttermilk, vegetable oil, and sour cream in a stand mixer on medium speed.
Incorporate sweetener. Add granulated sugar and mix until fully dissolved and the mixture appears pale.
Mix dry components. Whisk 375 grams of flour, baking powder, salt, and baking soda in a separate bowl.
Fold the batter. Combine dry ingredients into the wet mixture, mixing for less than thirty seconds to avoid overdeveloping gluten.
Prepare fruit filling. Mix chopped peaches, melted butter, dark brown sugar, cinnamon, and 32 grams of flour in a small bowl.
Swirl the batter. Pour base batter into the pan, distribute peach mixture on top, and create gentle swirls with an offset knife.
Bake the cake. Bake for 70 minutes or until a probe thermometer in the center reads 95 degrees Celsius.
Cool the cake. Allow the cake to cool completely in the springform pan to ensure proper structural setting.
Apply the glaze. Whisk powdered sugar, softened butter, heavy cream, and vanilla, then drizzle over the cooled cake.

Notes

Use room temperature dairy products to ensure a stable emulsion and prevent the batter from breaking.
Always weigh flour using a digital scale to avoid the density issues common with cup-based measurements.
Tent the cake with foil during the final stages of baking if the crust browns faster than the center sets.
Wait until the cake is completely cool before releasing the springform sides to prevent structural tearing.
