Preheat the oven to 350°F. Line the pan with parchment on the bottom. Spray sides of the pan with oil spray.
Cook the apples, honey, and lemon juice in a saucepan over medium heat until softened, for 5 to 7 minutes, drain the liquids from the slices and set aside.
For wet ingredients: With an electric mixer, beat the sugars, oil, and vanilla until blended. Add the eggs and zest and beat until all is incorporated but not overmixed.
For dry ingredients: In a separate bowl whisk flour, baking powder, xanthan gum, and salt. Add it to the wet batter and mix together well with a spatula or larges poon.
Pour the batter into the prepared pan and fan the apples in 2 concentric circles to cover the batter. In a small bowl, combine the sugar and cinnamon, then sprinkle the mixture over the top.
Bake the cake for about one hour, or until just set and lightly golden, then allow it to cool. Check often.
Nail This
The batter will look scarce, don’t freak out, it will rise.
You’ll need a 10-inch springform. If you use a smaller one, the cake will rise too high. If using a smaller pan just fill about 3/4 of the batter and reserve the rest for a mini torte.
You’ll notice the edges start to brown while the center is still soft. Watch carefully and remove when center is just set so you don’t burn the edges.
Flip it
Swap the apples out for sliced peaches or pears or even berries and make this year-round!
Leftover cooked apples? Fold them into muffins or pancakes!
If your batter is runny in the center (that’s happened to me more than once) it actually tastes super creamy and delicious spooned into a martini glass with a scoop of ice cream or coconut frosting (see page 00) on top.
Freezes extraordinarily well. Good emergency freezer cake for company!
