Heat up the cherries, lemon, agave syrup and vanilla extract. Mash the cherries and stir in the gelatine leaves. Let this rest.
Preheat the oven to 180 degrees.
In another bowl, mix the oats, self-raising flour, protein powder, cinnamon, and salt.
Add the agave syrup, apple sauce, liquid sweetener and cinnamon, and margarine. Knead it with your hands into a crumbly dough.
Divide half of the crumble mix over a oven dish and press it well. Add the cherries on top. Lastly, crumble the left over dough over it.
Bake for 20 minutes. Keep an eye on it, to make sure that the topping doesn't burn.
Add some yogurt if preferred.
