Tips for Perfect Keto Rhubarb Dream Bars
Achieving the perfect texture and flavor for your bars is easy with a few simple tips:
- Press the Crust Firmly: A well-compacted crust is essential for preventing crumbling. Use the back of a spoon or a flat-bottomed glass.

These Keto Rhubarb Dream Bars are fantastic on their own, but a sprinkle of fresh mint or a few sugar-free berries can elevate them further.

You can also experiment by adding a pinch of ground ginger or cardamom to the rhubarb custard for an extra layer of warmth and spice. A drizzle of sugar-free white chocolate over the top before chilling would also be a lovely addition!

FAQs
Can I use frozen rhubarb for these Keto Rhubarb Dream Bars?
Yes, absolutely! You can use frozen rhubarb directly without thawing. Simply add it to the custard mixture as specified in the recipe. Just be aware that it might release a bit more moisture, so ensure the custard is fully set before removing it from the oven.
What are the best tips for a firm crust that doesn't crumble?
To ensure your keto shortbread crust is perfectly firm and doesn't crumble, make sure to press the mixture very firmly and evenly into the prepared baking dish. A glass or the bottom of a measuring cup can help achieve a compact base. Also, baking it until lightly golden and allowing it to cool slightly before adding the filling is key.
How long do Keto Rhubarb Dream Bars last in the refrigerator?
These delicious low-carb rhubarb bars can be stored in an airtight container in the refrigerator for up to 5 days. For the best texture and freshness, it's always recommended to enjoy them within the first few days.
Can I make these Rhubarb Dream Bars dairy-free?
Making a dairy-free version is possible! You can substitute the heavy cream with full-fat coconut cream and use a dairy-free cream cheese alternative for the topping. Ensure your almond milk and whipped topping are also dairy-free to keep the recipe completely dairy-free.

Description
A delightful low-carb dessert featuring a tender almond flour crust, a tangy rhubarb custard filling, and a light, creamy topping.
Ingredients
½ cup almond flour
1 tbsp coconut flour
2 tbsp granulated erythritol (for crust)
â…› tsp salt
2 tbsp melted coconut oil
1 large egg
¼ cup granulated erythritol (for filling)
2 tbsp almond milk
2 tbsp heavy cream
½ tsp vanilla extract (for filling)
¼ tsp xanthan gum
1 cup diced fresh rhubarb (or frozen, unthawed)
2 oz cream cheese, softened
2 tbsp powdered erythritol
¼ tsp vanilla extract (for topping)
4 oz sugar-free Cool Whip, thawed
Instructions
Step 1: Preheat your oven to 350°F (175°C). Line an 8x8-inch (or similar small square) baking dish with parchment paper, leaving an overhang on two sides for easy removal, and lightly coat with cooking spray.
Step 2: In a medium mixing bowl, combine the almond flour, coconut flour, 2 tbsp granulated erythritol, and salt. Mix well. Pour in the melted coconut oil and mix with a fork until the mixture resembles coarse, moist crumbs.
Step 3: Press the crust mixture evenly and firmly into the bottom of the prepared baking dish to form a compact layer.
Step 4: Bake for 10-12 minutes, or until the crust is lightly golden brown. Remove from the oven and let it cool slightly on a wire rack while you prepare the filling.
Step 5: In a large mixing bowl, whisk together the egg, ¼ cup granulated erythritol, almond milk, heavy cream, and ½ tsp vanilla extract until smooth and well combined.
Step 6: Lightly sprinkle the xanthan gum over the egg mixture. Whisk vigorously for about 30 seconds to fully incorporate it and prevent lumps.
Step 7: Gently fold in the diced fresh or frozen (unthawed) rhubarb into the custard mixture.
Step 8: Carefully pour the rhubarb custard mixture evenly over the partially baked crust in the baking dish.
Step 9: Return the dish to the oven and bake for 30-40 minutes, or until the custard has set. A knife inserted into the center should come out clean. The top may be lightly golden.
Step 10: Remove the bars from the oven and let them cool completely on a wire rack at room temperature. This is crucial for the custard to fully set.
Step 11: While the bars are cooling, prepare the topping. In a medium mixing bowl, beat the softened cream cheese with the powdered erythritol and ¼ tsp vanilla extract until smooth and creamy.
Step 12: Gently fold in the thawed sugar-free Cool Whip until it's fully combined and the topping is light and fluffy.
Step 13: Once the rhubarb custard layer is completely cooled (and firm to the touch), spread the cream cheese topping evenly over it.
Step 14: Cover the baking dish and refrigerate the Keto Rhubarb Dream Bars for at least 2-3 hours (preferably longer, or overnight) to allow them to set completely before slicing and serving. Use the parchment paper overhang to lift the bars out before cutting.
Notes
For best results, use fresh, vibrant rhubarb when in season. If using frozen, there's no need to thaw. The chilling time is essential for the bars to set and slice cleanly.
