To make the Quaker's Oatmeal Crumble Apple Crisp recipe, combine Quaker oats, butter, brown sugar and apples, and top the mixture with a crumble made of sugars, nuts, oats and spices. Bake the mixture in an oven at 350 degrees Fahrenheit for 40 minutes.
Preheat the oven, and butter an 8-inch pie-baking dish. Wash, core and slice five Pink Lady apples, and toss them in a large bowl with 2 tablespoons of butter and 1/4 cup of brown sugar. Pour this mixture into the baking dish, and let sit. Although the recipe calls for Pink Lady apples, substitute other varieties if desired.
In a medium bowl, mix together 1/2 cup of flour, 1 cup of brown sugar, 1 cup of Quaker oats, 1/2 teaspoon of cinnamon and 1/3 teaspoon of salt. Once well-blended, add in 1/2 cup of almonds, 1 tablespoon of melted butter and 1/2 teaspoon of vanilla extract. Use your hands to blend these ingredients, and then spread the mixture over the top of the apples in the baking dish. The recipe is ready to serve after baking. Serving suggestions include adding a scoop of vanilla ice cream to the side or placing a dollop of whipped cream on top.
