Keto Rhubarb Tart With Frangipane Filling

Although I could have made this keto rhubarb tart without a layer of filling, the addition of frangipane takes this keto dessert over the top. If you are not familiar with frangipane, it’s a classic French almond flour-based paste made with eggs and sweetener. 

Made with fresh or frozen and thawed rhubarb it’s packed with flavor and the pink rhubarb makes for a stunning sight. The rhubarb tart with its luscious frangipane filling and tender almond flour crust, is a dessert that everyone will welcome, even those not doing a keto diet.

Keto Shortbread Crust- You’ll be making an almond crust for the rhubarb pie. The crust consists of almond flour, sugar substitute, salt, and melted butter. Once it’s mixed together it’s patted to the bottom of 10-inch tart pan with a removable bottom then baked until golden brown for about 15 minutes.

Keto Frangipane Filling- To make the frangipane filling, you’ll cook the butter over medium heat in a skillet pan until it’s lightly browned. Then in a large bowl combine the almond flour, sugar substitute, vanilla and almond extract, and salt. Add the browned butter to the almond mixture and then add the egg, heavy cream, and mix well. Transfer the filling to the top of the baked tart shell.

Rhubarb Topping- Add the rhubarb that has been sliced into 1-inch pieces on the bias to the top of the tart.  Sprinkle over the surface of the sliced rhubarb the granulated sugar substitute. 

Then it’s just a matter of baking the rhubarb tart for an additional 25- 30 minutes or until set and golden brown.  

Best Sugar Substitutes For Keto Rhubarb Tart

When it comes to choosing which sugar substitute to use for this sugar-free sour cream lemon pie, I have several for you to choose from. 

My go-to choice is Lakanto Monk Fruit because the texture is spot on and since there is barely any aftertaste. It is a monk fruit and erythritol blend.

Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. It’s why it’s a great all-natural sugar substitute and has zero calories and zero glycemic index.

I’m also partial to  Swerve an erythritol blend. Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures just like sugar.

Swerve is the name brand of Erythritol it’s unlike other sugar alcohols that have a 0 % impact on blood sugar.

You could also use the stevia and erythritol-based brand Pyure for this recipe.  However, if you decide to use Pyure you will want to use 1/2 the amount called for in this recipe since it’s a much sweeter option.

Lastly, if you can easily find a more natural sugar substitute you can also use Splenda with great success.

Join Our Jesus And Keto Movement 

Randy and I came to the keto diet looking at it from a Christian perspective. As believers, we live our lives supported by God’s grace.

So when the Holy Spirit led us to combine our Christian faith and the keto diet, we did so in hopes of finding lasting transformation.

To say we needed God’s intervention is putting it mildly. When we followed the Holy Spirit’s prompting to we got on the path to real transformation. 

Knowing firsthand the benefits of this decision we have created a closed Christian group that is using the keto diet to transform their lives.  We invite you to join our Private Facebook Group and see if it’s not the key you have been missing.
