Keto Strawberry Rhubarb Crisp

Updated: Oct 3

Was excited when I was looking up seasonal fruits and found that rhubarb is even less carbs than strawberries. So I immediately thought I should make a keto strawberry rhubarb pie! Which is possible but with adding in a keto crust the carb count gets a wee bit high for me personally. But totally doable with using my coconut flour crust as the bottom (recipe here : ) and I would absolutely use this crumble topping from the crisp on top because it is 0 carbs!!

Because we can't use oats in our crumble I just subbed in some oat fiber. Then tested using coconut flour, unflavored whey protein isolate and egg white protein. They all worked well but I chose the unflavored whey protein because it is 0 carbs. The coconut flour tastes sweeter because of the extra carbs in it. And the egg white protein was the crunchiest. The unflavored whey protein is crunchy and has 0 carbs, so I just upped the sweetener a little bit and got a great, sweet, crunchy topping for our crisp. So you can sub anything you want in for the unflavored whey protein, just the carbs will be different depending on what you use. If you use coconut flour make sure it is a crumbly consistency, you may need to add more butter because coconut flour is really absorbent.

The rhubarb and strawberries I weighed out because I never know how to measure fruit accurately to count the carbs. I cut everything into medium dices and got 2 cups of strawberries and 4 cups of rhubarb. It all depends on how you dice the fruit though, if you chop it smaller than I did you may have more in weight than me. If you have bigger chunks, less fit in the measuring cup. So if you are not weighing the fruit definitely watch the video to see how I chopped the strawberries and rhubarb to get an accurate measurement.

The sweetener I used for this recipe is just what I like to use. Any alternative sweetener can be used. I like using powdered monkfruit to coat the rhubarb and strawberries because it coats the fruit nicely. Can use swerve or any granular sweetener you like. Just remember powdered monkfruit is 2x sweeter than the granular version, so you may need to add more. I also like things a little sweeter so I add a few drops of liquid sweetener also. My boyfriend loved it without any extra sweetener, so it's all to taste.
