Preheat oven to 350℉. Spray your 6 inch round spring form pan with oil and then line it with parchment paper. I like to scrunch my paper and then it is more pliable to shape to the pan.
To a large bowl add the yogurt and then whisk in your eggs until the batter is silky smooth. Next sift in arrowroot flour and stir to combine. Next mix in 1/4 cup granulated sweetener, vanilla, pinch of salt until incorporated. Pour this batter into you pan.
In a small bowl toss the apple slices with 1 tsp cinnamon + 1 tbs sugar to coat all. Gently layer on the apple slices on top of the cake. Bake the cake for 1 hour - it will puff and turn golden brown. Allow to deflate, set and cool on your counter for 30-40 minutes. Then transfer to your fridge to fully set for 2 hour or up to overnight. Slice and serve with chopped pecans, honey drizzle or whipped cream!
Notes
Nutritional Information is for a cake made with Zero Sugar Erythritol granulated sweetener.
Store leftovers in an air tight container in your fridge.
If you don't have arrowroot powder or cornstarch, you can use tapioca flour or regular all purpose flour.
This cake is not super sweet. IF you would like a sweeter cake, simply add in more granulated sweetener.
