  • cast iron skillet or 8x8 baking dish
  • measuring spoons and scale or cups
  • mixing bowl
  • wooden spoon
  • knife
  • chopping board


  • 3 Bramley apples chopped (cooking or granny smith apples can be substituted - see notes*, can also be peeled and/or sliced)
  • 1/3 cup white erythritol
  • 1 3/4 tsp ground cinnamon divided
  • 1 cup brown erythritol
  • 1 cup almond flour
  • 66 g unsalted butter diced into small cubes
  • 1/2 cup walnuts chopped (or pecans)
  • pinch of salt


  • Preheat your oven to 350°F/175°C, and if you're using an 8x8 baking dish, grease it with butter. If you're using a cast iron pan, it'll be seasoned already.
  • Chop the apples and them to a mixing bowl along with the white erythritol and 1 tsp of the cinnamon. Mix well.

*If substituting Granny Smith Apples, you will need 5 or 6 as they are much smaller than Bramley apples. The carb count is also slightly higher so double check if they work with your macros.
