Keto Rhubarb Dream Bars – A Sweet, Tangy Treat Without the Carbs

There’s something special about biting into a dessert that has both sweet and tart flavors. That’s why rhubarb is such a hit. It brings a kick to baked goods without needing loads of sugar. And when you’re trying to stay low-carb, that makes rhubarb a solid choice.

These Keto Rhubarb Dream Bars are simple, satisfying, and great for anyone following a keto lifestyle. They are soft, a little gooey in the middle, and pack that rhubarb punch. This isn’t your average cake mix dessert. It’s a mix of creamy custard, buttery crust, and tangy rhubarb in one bite.

Why Rhubarb Works on Keto

Rhubarb is low in sugar, high in fiber, and low in calories. It fits well into low-carb plans. The stalks are the part you eat – the leaves are toxic, so don’t use those.

Rhubarb adds flavor without needing much sweetener. That’s rare. Most fruits are too high in carbs. But rhubarb, especially when paired with the right low-carb sweeteners, fits.

This recipe takes that idea and runs with it. The result? Keto rhubarb dream bars you’ll want to keep in your fridge all week.

Ingredients You’ll Need

Crust:

• 1 1/2 cups almond flour
• 1/4 cup coconut flour
• 1/3 cup butter (melted)
• 2 tbsp powdered erythritol
• Pinch of salt

Filling:

• 2 cups chopped rhubarb (fresh or frozen)
• 3 large eggs
• 3/4 cup powdered erythritol (or monk fruit sweetener)
• 1/3 cup heavy cream
• 1/4 cup unsweetened shredded coconut (optional)
• 1 tsp vanilla extract
• 1 tbsp coconut flour (for thickening)

You can add a few raspberries for color if you want to recreate a raspberry rhubarb slab bars vibe, but that may add some carbs.

How to Make Keto Rhubarb Dream Bars 

Step 1: Prep Your Pan

Use a 9×13 baking dish. Line it with parchment paper so you can lift the bars out later.

Step 2: Make the Crust

Mix almond flour, coconut flour, melted butter, sweetener, and salt. Press into the bottom of the pan evenly. Bake at 350°F for 12-14 minutes, or until lightly golden.

Step 3: Make the Filling

While the crust bakes, whisk together eggs, sweetener, heavy cream, vanilla, and coconut flour. Stir in chopped rhubarb. If you’re doing a twist like rhubarb coconut bars or want a nod to omas rhubarb cake, toss in shredded coconut.

Step 4: Bake Again

Pour the filling over the warm crust. Bake for another 30-35 minutes, or until the top sets. Let cool completely before cutting. They firm up as they chill.

Tips and Tricks for this Recipe

Use Fresh Rhubarb if You Can

Fresh stalks give better texture. But frozen rhubarb works too. Just thaw and drain it first.

Adjust Sweetness

Rhubarb is tart. If you like it sweeter, taste the filling before baking and add more sweetener if needed.

Try Variations

• Add a swirl of cream cheese for a rhubarb cheesecake dream bars twist.
• Mix in coconut for rhubarb coconut bars.
• Add crushed low-carb cookies on top for a crumble finish.
