Preheat your oven to 350 degrees f.
Line an 8x11 inch baking pan with parchment paper.
In a mixing bowl, add all shortbread crust ingredients and stir well until thoroughly combined. Add a few drops of almond milk or water if necessary.
Press this mixture into the bottom of your prepared pan and bake for 10-12 minutes, or just until the edges are nicely golden brown.
Allow your crust to cool for about 5 minutes, then evenly spread your chia seed strawberry jam on top.
In another mixing bowl, add all of your crumb topping ingredients and using a silicone spatula stir well to combine.
Sprinkle this crumb mixture evenly over your strawberry jam filling. Top with fresh raspberries as desired.
Place your pan into the preheated oven, and bake for 15-20 minutes, or just until nicely golden brown.
Remove from the oven and allow to cool before slicing and serving.
Enjoy!
