Can I use frozen rhubarb instead of fresh?

Yes, but thaw and drain it completely to avoid excess moisture in the custard layer.

How long will these keto bars last in the fridge?

Stored in an airtight container, they’ll stay fresh for 4 to 5 days. For longer storage, freeze individual bars.

What’s the difference between dream bars and custard bars?

Dream bars usually feature a shortbread base with a rich, often fruit-forward custard topping. The term “dream” usually refers to the smooth, almost mousse-like texture of the filling.

Can I make these bars dairy-free or nut-free?

For dairy-free, try using coconut cream in place of heavy cream and a vegan butter alternative. To go nut-free, experiment with sunflower seed flour as a substitute for almond flour.

Keto Rhubarb Dream Bars are the perfect low-carb dessert.

Instructions

Preheat oven to 350ºF (175°C).
In a bowl, mix almond flour, powdered erythritol, and salt. Add melted butter and stir to form a crumbly dough.
Press the dough into an 8×8 inch parchment-lined baking dish. Bake for 10 minutes.
While crust bakes, whisk egg yolks, granulated erythritol, heavy cream, and xanthan gum until lighter in color. Fold in rhubarb.
Pour the filling onto the pre-baked crust and spread evenly.
Bake for 45–50 minutes or until center is set and edges are lightly golden.
Cool completely before slicing. Optionally dust with powdered erythritol before serving.

Notes

Ensure rhubarb leaves are discarded—they are toxic.
Cool completely before slicing to maintain structure.
Store in the fridge for up to 5 days or freeze individually wrapped bars.
Add a meringue topping for a traditional twist.
Substitute half the rhubarb with berries for variety.
