Place berries in a small Pyrex oven dish and sprinkle a little Stevia on top.
Mix together protein powder, oats, and lemon juice. It will be fairly dry. Chop the almonds into small pieces and mix them with the crumble.
Spread the crumble on top of the berries.
Bake for 15 min, then set the oven to broil and bake the crumble for another 1-2 minutes until the top is slightly golden.
Take out of the oven and allow to cool slightly before serving.
This recipe is for 1 serving of berry crumble.You can substitute the protein powder in this recipe with oat flour and a little vanilla.If making a larger batch, don't make your crumble too big or it will overcook the berries before the center of the crumble is done. Instead, make small, individual portions.I do not recommend making this recipe ahead of time as the crumble topping will become soggy and lose its crunch.
