Preheat oven to 350 degrees.
In a saucepan heat the frozen cherries, water, sugar, starch and salt over medium heat.
Heat until it thickens for about 5 minutes.
In a separate bowl mix together the dry ingredients almond flour, potato starch, sugar, baking power, salt. Once mixed add the melted coconut oil, eggs, vanilla, milk.
I use non-stick spray in a 9×9 baking pan. Add coffee cake batter, reserving 1/2 cup.
Pour in cherry filling, and level with spatula. Add tyhe remaining cherry filling.
Place in the oven @ 350 degrees for 45-50 minutes.
