Instructions
Prep: Heat the oven to 350℉. Butter an 8" x 8" glass baking dish and set aside (a deep glass pie dish also works well.) Peel and chop the apples into bite-sized pieces, and place in a large bowl.
Make the filling: Add the rest of the filling ingredients to the apples and mix everything well to incorporate.
Make the topping: In a separate medium bowl, gently mix the oats, flour, brown sugar, cinnamon and salt together with a whisk. Cube and add the cold butter, and use a pastry cutter or your hands to work everything into a crumbly mixture.
Assemble: Pour the apple filling into an even layer in the greased baking dish and then sprinkle in the topping mixture using your hands to even everything out.
Bake: Bake for 45-50 minutes on a middle rack in the oven and remove once the topping is just browning and turning into a nice crisp.
Make the whipped yogurt: Meanwhile, chill a clean mixing bowl and the whisk attachments from your mixer in the freezer for about 5 minutes. Remove them and add all of the whipped yogurt ingredients to the bowl, gradually increasing the speed on your mixer for about 2-3 minutes or until gentle peaks form. Do a taste test and blend in a little extra sugar if necessary.
Enjoy: Cool the apple crisp for at least 5 minutes once it's out of the oven, serve and top with whipped Greek yogurt, and enjoy!
Notes
Apples: Look for Golden Delicious or Honeycrisp apples if you can find them (both are great baking apples) but any other varieties will work too.Oats: Make sure you use certified gluten free oats in the case of Celiac disease or gluten sensitivity, to avoid cross contamination issues with wheat. I like Bob’s Red Mill Gluten Free Organic Old Fashioned Rolled Oats which is certified gluten free.Gluten-free: Substitute an all-purpose gluten free flour blend for the flour, and see notes under oats above. I tested with Bob's Red Mill 1 to 1 Gluten Free Baking Flour and it worked well.Vegan: Use coconut oil instead of butter and skip the whipped yogurt (the crisp is still amazing on its own!)No oats: To make apple crisp without oats, substitute finely chopped walnuts in place of the oats.
