3/4cupSharon’s Nightshade-Free Gluten Free Flour Blend(103g, see notes)
1/2teaspoonXanthan Gum(2g) - omit if your flour blend contains it
1/3cupGranulated Sugar(73g)
1/3cupLight Brown Sugar(75g)
1/4teaspoonFine Sea Salt
1/2cupGluten Free Old Fashioned Oats(50g)
1/2cupButtercubed and cold (4 ounces)
Instructions
Preheat oven to 350°F and lightly spray a 9x9 inch baking dish or 9-inch deep dish pie plate with non-stick spray.
In a large bowl, combine the sliced apples, orange zest, lemon zest, lemon juice, brown sugar, cinnamon, nutmeg, and cornstarch. Mix well and pour into the prepared baking dish.
To make the topping, add the flour, granulated sugar, brown sugar, salt, and oats to the bowl of a stand mixer fitted with the paddle attachment. Mix to combine.
Add the cubed butter and mix on low to incorporate. When the dough starts to come together, crumble it over the top of the apples.
Place the baking dish over a rimmed baking sheet (in case the apples bubble over) and bake at 350°F for 45 minutes or until the topping is browned/crisp and the apples are bubbling.
Serve warm with vanilla ice cream or homemade whipped cream.
Notes
I used a mixture of 3 Granny Smith Apples, 1 Honey Crisp Apple, and 1 Golden Delicious Apple but any combination of baking apples will work!
