Grease your donut pan WELL - you don't want any sticking! I like to grease with coconut oil spray. Preheat the oven to 350°F.
In a medium mixing bowl, whisk together the oat flour, almond flour, tapioca flour, baking soda, and salt.
¾ cup (96g) gluten-free oat flour, ½ cup (48g) superfine blanched almond flour, 3 tablespoons (24g) tapioca starch, 1 teaspoon baking soda, ½ teaspoon fine salt
In a separate bowl or liquid measuring cup, combine the melted chocolate, maple syrup, applesauce, coffee, apple cider vinegar, and vanilla extract. Make sure all of the ingredients are warm or room temperature so the chocolate doesn't seize up.
½ cup (3 oz) Raaka Baking Chocolate, ⅓ cup (112g) pure maple syrup, ⅓ cup (70g) unsweetened applesauce, 6 tablespoons (90g) coffee, 1 teaspoon apple cider vinegar, 2 teaspoons vanilla extract
Whisk the liquid ingredients into the dry ingredients, until a smooth batter forms.
Immediately fill each donut cavity very well, almost to the top. This will help give you nice and fluffy donuts.
Bake for 11 to 13 minutes, or until firm and fluffy to the touch. Let cool almost completely before removing from the pan.
Clean the pan and repeat with the rest of the batter. It may have thickened while the other donuts baked - that's okay, just press it into place. Bake and cool.
