Nothing better than brown sugar and cinnamon!
Ingredients for Topping
1/2 C oats
1/2 C flour (GF baking mix also works)
1 stick butter, softened
3/4 C brown sugar
1/4 C white sugar (or you can do all brown sugar)
1 tsp cinnamon
1/4 tsp nutmeg
1/4 tsp salt
Combine all ingredients for topping except butter. Cut butter into the mixture.
Crumble dough on top of apples evenly. Place lid on slow cooker and cook on high for 2 hours, or low for 4 hours. Open lid partway and cook for about an additional hour to let top get crispy.
Supposedly this makes 6 servings, but it could be single-serving sized if you’re not careful!
