I love apple desserts, just as much as the next person! My recipes for apple pie bars, apple crisp, and apple pie roll ups are some of my favorites until I thought about adding protein to the apples and healthy fats of apple crisp. This recipe has all the flavor and nostalgia of an apple pie, but with protein.

Recipe Ingredients

All the ingredients needed to make the protein apple crisp laid out before baking.
  • Unflavored Protein Powder. I like to use this unflavored protein powder, but you should be able to use any you like.
  • Arrowroot Starch. Tapioca starch should work here as well.
  • Maple Syrup. I like the flavor of maple syrup in this recipe, but honey should work as well.
  • Oats. Make sure to buy gluten-free oats if you need them! I like One Degree brand.
  • Honeycrisp apple. These are my favorite apples to use in this recipe, but you could use other varieties if you have on hand.

Recipe FAQS

  • Use a small baking dish. This recipe is made with a 7×5.25″ baking dish (I use this set). If you don’t have that exact size, be sure to use something similarly small as using a baking dish that’s too big can cause the recipe to cook unevenly.
  • Be sure to let it sit for a few minutes! The filling will be a bit liquidy (as most baked apples are) right out the oven, but it will firm up a bit after it sits for a few minutes.

Storage and reheating instructions

This recipe is best fresh, but if you do choose to save it for later, simply store it in the fridge for 1-2 days and cover and reheat in the microwave, air fryer, or oven.
