Method
- Preheat your oven to 325 degrees F (160 degrees C). Prepare two 8-inch cake pans by greasing them with shortening and dusting with flour to prevent sticking.
- Divide the melted butter evenly between the two cake pans, brushing it to cover the bottom. Distribute the brown sugar over the butter layer in each pan. Arrange the peach slices in an even layer on top of the brown sugar. Set the prepared pans aside.
- In a large bowl, whisk together all the cake ingredients except for the cake mix. Sift in the cake mix and gently stir until just combined. Divide the cake batter evenly between the two prepared cake pans.
- Bake for 30-32 minutes, or until a toothpick inserted into the center comes out clean. Remove the cake pans from the oven and invert them onto a wire rack to cool completely. Once cooled, wrap the cake layers carefully in plastic wrap and freeze for at least 30 minutes to make assembly easier.
- For the buttercream: In a stand mixer fitted with a paddle attachment, whip the softened butter until light and fluffy. Add the salt, vanilla extract, and heavy cream, and whip again. Scrape down the sides of the bowl. With the mixer on low speed, gradually add the powdered sugar. If the mixture is too thick, add 2-3 tablespoons more heavy cream to reach the desired consistency. Increase the mixer speed to high and beat for 2 minutes until the buttercream is light and fluffy.
- To assemble: Place a small amount of buttercream on the center of a cardboard cake round to secure the first cake layer. Place the first cake layer, fruit side up, onto the cardboard round. Spread a layer of buttercream over the cake. Apply a thin layer of buttercream to the sides of the cake for a crumb coat, leaving the top exposed. Add a layer of buttercream around the sides of the cake. Using a cake turntable and a scalloped cake comb, carefully create a textured finish on the sides of the cake.
- Slice and enjoy your homemade peach upside down cake!
Notes
For best results, ensure your eggs, sour cream, and buttermilk are at room temperature before mixing the cake batter. The optional peach flavoring can significantly enhance the peach flavor in the cake.
