2 large Granny Smith apples, peeled and cut into ½-inch slices
½ cup vegetable oil
½ cup granulated sugar
1 egg
1 teaspoon vanilla extract
1 ¼ cups all-purpose flour
2 teaspoons baking powder
½ teaspoon salt
½ teaspoon apple pie spice
½ cup milk
Directions
Preheat the oven to 350 F.
Place a piece of parchment paper in the bottom of a 9-inch round cake pan and spray the pan with nonstick cooking spray.
Add the butter to a medium saucepan and melt over medium heat.
Add in the brown sugar and stir until it is combined with the butter.
Bring the mixture to a boil and boil for about 1 minute, until bubbly.
Pour the mixture into the prepared cake pan and spread it out evenly.
Arrange the cut apple slices on top of the caramel sauce.
In a large bowl, whisk together the vegetable oil and granulated sugar until smooth.
Add the egg and vanilla extract and whisk until combined. Set aside.
In a separate bowl, whisk together the flour, baking powder, salt, and apple pie spice.
Add about half of the flour mixture and half of the milk into the bowl with the wet ingredients and whisk until combined. Repeat with the rest of the flour and milk.
Pour the cake batter over the apple slices in the cake pan.
Bake in the preheated oven for 40–45 minutes, until the cake is golden brown and a toothpick inserted into the center comes out clean.
Let the cake sit for 20 minutes in the pan to cool, then run a butter knife around the inner edge of the cake pan and invert the cake onto a serving plate.
