Keto Raspberry Crumble Cake Slices

Sugar Free + Low Carbs

These keto raspberry crumble cake slices are sugar free, grain free, gluten free and are low in carbs. And that doesn’t take anything away from the taste. They’re sweet but sugar free. These crumble cake slices are so yummy, even the kids love them.

You don’t have to make a raspberry slice, you can change up the fruit filling. However, raspberries are the most keto berry, and I love them!

Sugar alternatives

When baking sugar free, I like to use a mixture of sweeteners in order to make my perfect sugar alternative sweetener. I mix xylitol, erythritol and a little stevia. For this recipe I mixed 4 ounces xylitol, 4 ounces erythritol and two tablespoons of stevia.

  3. Spread over the bottom of the lined pan.
  4. Spread the jam over the crust base.
  5. Add the crumble ingredients (apart from the oats) to a food processor and pulse until large crumbs form. (Alternatively, mix by hand, rubbing between fingertips). Add the oats and continue to pulse/mix until mixed in.

These bars should be stored in an air tight container and kept in the fridge. They will last for 4-5 days. Alternatively, you can freeze them for up to 2 months.
