Preheat your oven to 350°F (175°C). Line a 9x9-inch pan with parchment paper.
Blend the crust ingredients in a food processor until they form a dough. Press evenly into the prepared pan.
Combine raspberries, sweetener, and lemon juice in a small saucepan. Cook over medium heat for 5 minutes until bubbling. Gently mash the berries and stir in xanthan gum.
Spread the raspberry jam over the crust.
Mix the crumble ingredients (excluding oats) in the food processor until large crumbs form. Add oats and pulse briefly. Sprinkle evenly over the jam.
Bake for 40 minutes until golden brown. Let cool before slicing.

Feel free to swap any of the ingredients with your preferred keto-friendly options. Enjoy!
