All Purpose Crumb Topping

This all purpose crumb topping is good on pies, fruit crisps, coffeecakes, muffins, you name it. I like using Sorghum and Chickpea or All Purpose Sorghum blends, but Bob's Red Mill All Purpose Gluten Free Flour Blend works well too. Go here for Nut Free Crumb Topping.1 cup GF flour blend 1/4 cup brown sugar 2 tbsp. white sugar 1/2 tsp. cinnamon 8 tbsp. dairy free, soy free margarine 1/2 cup
