Fresh blueberries with cinnamon-streusel topping, finished off with vanilla bean ice cream— AND it’s keto? Unbelievable!

Honestly, this recipe was a bit of an experiment. Truth be told, over the 4th of July, I decided to indulge my party guests (and myself) with a homemade blueberry crumble pie. And if I was jumpin’ keto ship for the day, I was gonna do it right— flaky butter crust, decadent streusel topping, and a scoop (or two) of Häagen-Dazs® vanilla ice cream. Holy moly was it good!
The only problem is, I haven’t been able to get it outta my head! And I’m not talking about the guilt of going off keto for the day— no shame here— I’m saying I can’t stop thinking about how much I want another pie.
So this recipe is actually an attempt to recreate the foodgasm that took place on July 4th without compromising my ketogenic diet. And fortunately, this pie does just that!

Can You Bake This in a Dish Rather than a Pie Pan?
Absolutely!
In fact, next time around I’d use a 9×13 baking dish because the outcome is much more of a crumble than it is a pie. In fact, if you were hoping for a picture-perfect presentation you’re going to be sorely disappointed!
The best way to serve this “pie” is in a bowl, as a crumbled mess— with a spoon of course.

Notes
Fresh out of the oven this pie looks beautiful. However, once you slice into it, you’ll quickly realize this is much more of a crumble than it is a pie. Which explains why the serving size is coming to you in 1/2 cup portions. Don’t worry, it doesn’t take away from the flavor. Just serve it up in bowls with a spoon and you’re good to go!
*Option to use coconut flour, but the crust won’t be as flaky and the topping won’t be as crispy.
*I prefer the brand Swerve.
*Again, I prefer the brand Swerve.
*Or another keto-friendly ice cream.
*This is not a smooth operation. Meaning, your pie crust is going to fall apart before it hits the pie pan (or dish). Don’t worry, simply patch it back together with your fingers. No one will ever know it’s a sloppy mess underneath all those blueberries.
