Preheat oven to 350℉ and line an 8x8 pan with parchment paper. In a bowl, mix all of the crust/crumble ingredients until well combined.
Press ⅔ of the dough into the prepared pan, saving the rest for crumbling on top. Bake for 10 min.
In a medium saucepan, add your raspberries and cook over medium-low heat until you can start to mash them. Begin mashing them together.
Add the rest of the filling ingredients and continue cooking until you have a thick jam filling.
Spread the filling over the baked crust, add the rest of the crust dough crumbled over top of the berries, and return to the oven to make for another 18-20 min. Let cool completely before slicing and enjoying!
