To prepare a peach walnut spice cake cake recipe, first you need to prepare your ingredients. First, you'll need peaches, walnuts, sugar, butter, eggs, vanilla extract, flour, baking powder, cinnamon, nutmeg, and salt. You will also need butter and eggs. Then you will need your cake batter. Preheat the oven to 350?F (180?C) and grease and flour two 8-inch round cake pans. Add the dry ingredients to the wet ingredients and mix until just combined. Pour the batter into the prepared pan and bake the cake for 35 to 40 minutes or until the toothpick inserted in the center comes out clean. Allow to cool for 10 minutes before removing from the pan.
