I made this for Christmas this year and besides being really easy, it was a huge success.
I also prepped it the day before, so just had to throw in the oven after the Christmas dinner was served up.
Very easy!
Serves 6, but can be doubled easily
6 cups mixed berries (raspberries, blackberries, blueberries, and hulled/chopped strawberries)
1/2 cup sugar
1 tbsp lemon juice
2 tbsp cornstarch
1/4 tsp cinnamon for berries
1/4 tsp cinnamon for the crumble
1 cup oat flour
1/2 cup brown sugar
1/2 tsp salt
1/2 tsp baking powder
1 cup butter, chilled
1/2 cup walnuts, chopped (optional)
In a large bowl, combine berries, sugar, lemon juice, and 1/4 tsp cinnamon. Add cornstarch and toss to coat berries. Transfer to a baking dish or oven-safe skillet.
In a bowl, combine flour, 1/4 tsp cinnamon, brown sugar, baking powder, and salt. Whisk until distributed.
Cut in the butter and using hands, rub the butter into the flour mixture until large crumbs form. Stir in walnuts, if using.
Sprinkle mixture over top of berries to completely cover.
Bake in a 375 F oven for about 30 to 35 minutes or until golden brown and bubbly.
Remove from oven and let stand for about 5 minutes.
Serve warm. Top with vanilla ice cream, if desired.
