Preheat the oven to 350F. Line a 9” springform pan with parchment paper.

Clean and slice the apples and add to a bowl and toss with 1 Tbsp flour.

In a large bowl, beat the eggs and sugar together with a blender on high for 5 minutes. Add in the vanilla, oil, and sour cream and gently fold with a spatula.

Sift together the flour and baking powder. Add half the dry ingredients into the wet ingredients and gently fold then add remaining flour mixture and carely fold in with the spatula.

Add the apples into the batter reserving about ¼ of the apples for the top.

Spread the batter evenly into the prepared pan and add the remaining apples on top.

Bake at 350F for 35-40 minutes, or until golden and a toothpick runs clean. Allow to cool in the pan for about 10 minutes.

Run a sharp knife around edges of the pan and release the pan.

Top with powdered sugar, slice and serve.

Enjoy!
