1. Prepare the Cheesecake Filling:
- In a blender or food processor, combine the cottage cheese, softened fat-free cream cheese, protein powder, sugar-free maple syrup, and vanilla extract.
- (For Chocolate Version: Add 1 tbsp cocoa powder here).
- Blend on high speed until the mixture is completely smooth and creamy. This is crucial for the texture. Stop and scrape down the sides of the container as needed to ensure everything is well-mixed and no lumps remain. This may take 1-3 minutes.
2. Prepare the Crumb Crust:
- Place the keto (or regular) graham crackers into a clean blender or food processor (or place in a resealable bag and crush with a rolling pin).
- Pulse or crush until the crackers are finely ground into crumbs.
- Transfer the crumbs to a small bowl. Add the melted butter and mix with a fork or spoon until the crumbs are evenly coated and slightly clumpy.
3. Assemble the Jars:
- Spoon a layer of the graham cracker crust mixture into the bottom of each of your four jars or serving dishes. Press down gently if desired.
- Carefully spoon or pipe the blended cheesecake filling evenly on top of the graham cracker crust layer in each jar.
4. Chill:
- Place the assembled jars in the refrigerator.
- Chill for at least 1-2 hours. This allows the flavors to meld and the cheesecake filling to set and firm up slightly.
5. Add Toppings and Serve:
- Just before serving, top each cheesecake jar with fresh fruits of your choice (like berries) or a dollop of blueberry jam.
- Serve chilled and enjoy your high-protein treat!
