Finely mill the wheat berries into a medium bowl.
255 g soft white wheat berries, 120 g einkorn berries
Add the salt, baking powder, baking soda, and ground cinnamon to the freshly milled flour. Whisk to combine.
5 g salt, 2 tsp baking powder, 1/2 tsp baking soda, 2 1/4 tsp ground cinnamon
Add the apples and toss to coat in the flour.
120 g apples
To a large mixing bowl, add the sourdough discard, sugar, avocado oil, eggs, applesauce, and vanilla extract. Whisk to combine.
100 g sourdough discard, 150 g cane sugar, 113 g avocado oil, 3 large eggs, 177 g applesauce, 2 tsp vanilla extract
Add the flour with apples to the wet ingredients and gently stir until no dry flour remains in the bowl.
Cover the bowl and let the batter rest for 15 minutes.
Preheat your oven to 400℉ and line the muffin pans with parchment liners.
Scoop the batter into the muffin pans and bake for 8 minutes. Then turn the oven temperature down to 350℉ and bake for an additional 12 minutes until lightly golden brown. A toothpick inserted in the middle of a muffin should come out clean.
Cool the muffins in the pan for 5 minutes before transferring to a wire rack to cool completely.
