Step-by-Step Guide to Making Keto Raspberry Crumble Bars
Preparing the Crust and Oven
Start by preheating your oven to 350°F. Grease or line your 9×9 baking pan with parchment paper to ensure easy removal later. In a mixing bowl, combine all crust and crumble ingredients until crumbly. Press half of this mixture into the bottom of the prepared pan.
Crafting the Delectable Raspberry Filling
While your crust bakes for 10-12 minutes, combine the filling ingredients in a medium saucepan over medium heat. Bring the mixture to a boil, then let it simmer for about 25-30 minutes, stirring frequently until it thickens and the berries soften. Mash some of the raspberries, leaving a few chunks for texture.
Assembling and Baking Your Crumble Bars
Once the crust has cooled, spread the raspberry filling evenly over it. Top with the remaining crumble mixture, ensuring an even layer. Bake for another 15-20 minutes until the topping is golden brown. Let them cool before cutting into squares.
