Step 1

Heat 1 tablespoon butter in a 12" skillet over medium heat and cook the apples, rhubarb, sugar, lemon juice, cinnamon, vanilla and a pinch of salt for about 5 minutes.

Step 2

Pre-heat your oven to 350 degrees.

Step 3

Stir the dry crumble ingredients in a medium bowl with a fork, then stir in the melted butter. Use your hands to finish mixing and keeping the large crumbles intact. Be careful not to over-mix and turn the crumble to dust.

Step 4

Grease a 7x10x5" baking dish (or pie dish) with butter wrapper or cooking spray.

Step 5

Place a layer of crumble on the bottom and sides, saving enough for the top (the most important part).

Step 6

Add filling, then sprinkle the remaining crumble on top.

Step 7

Bake for 30 to 45 minutes, or until the crumble turns golden.

Step 8

Let cool and serve with ice cream or whipped cream.
