Preheat oven to 350F and prepare your standard donut mold with non-stick spray and be generous.
Step 2 -
Place your egg, sugar, applesauce and almond milk into a mixer and beat until fluffy. In a separate bowl, stir together the flour, protein, baking powder and soda. Add your dry ingredients into the mixer and stir until combined.
Step 3 -
Fill 5 donut molds with half way with batter (this should use about 3/4 of the batter). Spoon a layer of jam and a layer of peanut butter into the center of the batter and cover with remaining batter. Bake donuts for 11-12 minutes. Remove from oven and then let them cool completely.
Step 4 - For the glaze
Whisk ingredients together until smooth or place into a blender on high until smooth. If glaze is too runny add another 1/4 cup of confectioner's sugar.
