With the citrusy zing of lemon juice and sweet/tart dichotomy found in fresh raspberries, these low carb raspberry lemonade bars are a dream come true for anyone who prefers a pucker-inducing dessert to one that's overly sweet. A shortcrust pastry base made with keto-friendly almond flour and a touch of erythritol balances out the tangy filling for the ideal flavor equilibrium in every bar.

To make the raspberry puree

1. Combine the berries and water in a blender and blend until pureed. Strain through a sieve to remove the seeds, pressing on the solids to release as much juice as possible. This should yield at least 1/3 cup raspberry puree.
2. Discard the seeds and set the puree aside.

To make the crust

1. Preheat the oven to 325F and line a 9" square baking pan with parchment paper. (If using an 8" square pan instead, increase your crust and filling bake times by a few minutes and follow visual cues for doneness.)
2. In a large bowl, whisk together the almond flour, sweetener, and salt. Stir in the melted butter until the mixture begins to clump together.
3. Transfer mixture to prepared baking pan and press firmly and evenly into the bottom. Bake 12 minutes, or until edges are just starting to turn golden brown. Remove from oven and let cool completely.

To make the filling

1. Preheat oven to 325F.
2. In a large bowl, whisk together 1/3 cup of the raspberry puree, the whole eggs, egg yolks, sweetener, lemon zest, and lemon juice. Sprinkle the coconut flour over top and whisk to combine well.
3. Pour the filling over the cooled crust and bake 25 to 35 minutes, or until the top is just barely set to the touch. Remove and let cool to room temperature, then refrigerate at least 1 hour to firm up before cutting and serving.

Farm Team Tips

Can I make these dairy free? You bet! Simply replace the butter with a dairy free oil of your choice and keep a close eye on the crust while it bakes as it may need less time than a butter crust.

Can I skip the coconut flour? The coconut flour is what thickens the filling and helps it set properly, so skipping this important ingredient isn't recommended.

How do you store keto raspberry lemonade bars? Custard based desserts like this one should always be stored in an airtight container in the fridge.
