Step 1

Oven Preparation and Pan Setup: Begin by preheating your oven to 350 degrees Fahrenheit. Prepare a springform pan by lightly coating it with cooking spray to prevent sticking.

Step 2

Preparing the Crumble: In a small mixing bowl, combine the flour, light brown sugar, granulated sugar, cinnamon, ginger, nutmeg, and salt. Stir these dry ingredients until they are thoroughly mixed. Gradually pour the melted butter over the mixture, folding it together until it forms an evenly crumbled texture. Set this mixture aside.

Step 3

Assembling the Cake Batter: In a medium-sized bowl, sift together the flour, baking powder, baking soda, and salt to ensure they are well mixed. Place this bowl aside.

Step 4

Creaming Butter and Sugar: Utilize a stand mixer equipped with a paddle attachment to cream together the butter and granulated sugar until the mixture is light and fluffy. Incorporate the eggs one at a time, followed by the vanilla extract, ensuring each is well integrated before adding the next.

Step 5

Combining Liquid Ingredients: In a separate, small bowl, whisk together the sour cream and buttermilk until smooth.

Step 6

Mixing Dry and Wet Ingredients: Alternately add the dry flour mixture and the buttermilk mixture to the creamed butter and sugar, starting and ending with the dry ingredients. Add about half a cup at a time, mixing just until combined after each addition. Be careful not to overmix.

Step 7

Layering and Baking the Cake: Pour the prepared cake batter into the greased springform pan. Evenly arrange the sliced peaches on top of the batter. Generously sprinkle the previously prepared crumble mixture over the peaches. Place the pan in the preheated oven and bake for approximately 50 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Step 8

Cooling and Serving: After baking, allow the cake to cool on a wire rack until it is mostly cool. Serve the cake warm, optionally accompanied by ice cream, to enhance the flavor. Enjoy your meticulously prepared Southern Peach Crumb Cake.
