Preparation Steps

• Preheat oven to 350°F (176°C) and spray the sides of a 9x2 inch cake pan.
• Combine the melted butter, brown sugar, cinnamon, and nutmeg. Spread evenly in the bottom of the prepared cake pan.
• Arrange the apple slices over the sugar mixture. Arrange them around the outer edge of the pan and then fill in the center.
• In a medium bowl, whisk together the flour, baking powder, cinnamon, nutmeg, and salt. Set aside.
• In a large mixer bowl, beat together the softened butter, vegetable oil, sugar, brown sugar, and vanilla extract until light and fluffy, about 2-3 minutes.
• Add the eggs one at a time, mixing until mostly combined after each addition. Scrape down the sides of the bowl as needed.
• Add half of the dry ingredients to the batter and mix until just combined.
• Slowly add the milk and mix until well combined. The batter may look a little curdled, which is okay.
• Add the remaining dry ingredients and mix until well combined and smooth. Scrape down the sides of the bowl as needed. Do not overmix.
• Pour the batter over the apples in the prepared cake pan and spread evenly.
• Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. If the top starts to over-brown, cover loosely with foil for the last 10-15 minutes of baking.
• Remove the cake from the oven. Gently press down on the cake with a spatula to flatten any dome.
• Let the cake cool in the pan for 20 minutes before inverting it onto a wire rack. Allow to cool slightly before serving.
