Crispy Crumble Instructions
Place the measured oat flour, rolled oats, cinnamon, dark brown sugar, and salt in a medium bowl. Toss and mix until all is incorporated.
Cut butter into 1/4 inch slices and place in the bowl. Take your pastry blend and incorporate until texture resembles lumpy potatoes.
Do not allow butter to soften. Spoon crispy crumble topping onto the top of the slightly cooked blueberry mixture with a large ladle or use your hands. Make sure the topping is slightly lumpy and do not mash it with your hands.
Place in the oven still at 350 Fahrenheit for 30 -35 minutes until the topping is firm, lightly toasted and the blueberries are bubbly around the edges.
Allow to cool with out covering for 30 to 45 minutes. This allows the topping to dry out and the blueberry filling to set. Crisp should still be slightly warm when serving.
Top with your favorite topping. We recommend sweet whipped cream or vanilla ice cream.
Notes
Always use cold butter to cut into your topping, otherwise you risk it becoming to mushy.Adding oat flour to the berries allows it to thicken to a nice bubbly consistency when done. Precooking berries for 10 minutes ensures the berries are cooked through.The dish is done when topping is a light toasty brown and berries are bubbling around the edges of the crispy crumbles.Tip: You can make your own whipped cream with GF powdered sugar and GF heavy whipping cream
