Keto Berry Crisp

This Keto Berry Crisp is made with a mixture of juicy blueberries, blackberries, and raspberries all topped off with a crisp, buttery topping. This simple low carb dessert is perfect topped with sugar-free ice cream!

Oh boy, am I excited to share this keto berry crisp recipe with you!

Nothing says summer to me quite like a sweet treat that’s bursting with fresh berries. Our keto blackberry cobbler is a major favorite around here, so we thought we’d mix in a few more berries and really liven things up!

The rich, buttery topping is a breeze to mix up (one bowl, stir together with a fork, boom, done!) and nothing beats sticky berries that have baked until the juices are bursting out. Pair all that with your favorite keto vanilla ice cream and you’ve got an insane summer dessert that really only takes about 10 minutes of prep!

Not much of a cobbler fan? Our keto strawberry shortcake and raspberries and cream are a couple of other favorite ways to enjoy summer fruit!

ingredients for keto berry crisp recipe.

For the filling:

Fresh Berries – We’re using fresh raspberries, blackberries, and blueberries. I’ve only tested this with fresh berries, but I do think frozen will work, though they may produce more liquid in the bottom of the dish.

Xanthan Gum The xanthan gum works as a low carb and gluten free thickening agent. There is a lot of juice in fresh berries that’ll get released as it bakes. This will help keep the dish from becoming soupy.

SweetenerWe use and love Lakanto products. We’re using their original sweetener in this recipe. It bakes and tastes like real sugar with no impact on blood glucose, so it can be counted as ZERO net carbs! Use code THATLOWCARBLIFE for 20% off your order at Lakanto.

Lemon Juice – Some freshly squeezed lemon juice is preferable, but you can use the bottled kind too.

For the topping:

Almond Flour – We prefer finely ground almond flour. We haven’t tested this topping with other types of flour.

Butter – Melt it and stir it right in.

Sweetener – While you can use the classic sweetener if that’s all you have on hand, we love the brown sugar replacement from Lakanto in the topping. It adds a richer flavor.

Cinnamon – You’ll mix this up with the sweetener to go into the crumbly topping for lots of cinnamon sweet flavor!

Shop Keto Ingredients

We use Thrive Market for a lot of our specialty ingredients and keto snacks or products. Their prices tend to be cheaper than the local stores and I love that you can so easily sort products by diet.

Like Costco, this is a membership site, but we find that it’s more than worth it based on the amount we save over the regular grocery store.

They have monthly or yearly plans. Check it out here.

Why We Love This Recipe:
  • Fresh berries are perfect for a summer dessert!
  • Everything mixes together in 2 bowls – one for the filling, one for the topping. No mixer needed.
  • Takes about 10 minutes of hands on time and then 25 minutes in the oven. So quick!

How To Make Berry Crisp:

  • Filling – To get started you’ll prepare the sweet triple berry filling. Add the blackberries, raspberries, and blueberries to a large mixing bowl along with the sweetener, lemon juice, and xanthan gum. Stir it to combine and pour the mixture into a 9×9 or similar sized baking dish. berry crisp topping in small bowl.
  • Topping – In another mixing bowl add the almond flour, melted butter, sweetener, and cinnamon. Stir it up well until it forms into moist crumbs. almond flour topping over berries in white dish.
  • Sprinkle – Once you’ve finished preparing the topping you know what to do! Start sprinkling it over the top of the berry filling.
  • Bake – Pop this in the oven for 25 minutes. The topping should be a crisp golden brown with a bubbly, juicy berry filling! Let it cool for 5 minutes before serving. I’d recommend topping it with some keto whipped cream or some low carb vanilla ice cream!
Ingredient Spotlight

Xanthan Gum

Xanthan gum has an odd name, but it’s just a soluble fiber used as a low carb thickener and stabilizer used in many products, including salad dressings and toothpastes. It’s in many commercial products and we use it at home to thicken foods, such as in our keto beef stew or to thicken up the juices in this berry crisp. A little bit of xanthan gum goes a really long wa, so you won’t need much and it’ll last forever.

How to store berry crisp?

You can keep the baked keto berry crisp stored in the refrigerator for about 3 days. Make sure it is well wrapped or in an airtight container.

Can I use frozen berries?

We’ve only tested this recipe with fresh berries, but frozen would likely work. We would thaw them first. There may be more liquid at the bottom of the dish as well.

Berries: We've only tested this recipe with fresh fruit. If you want to try with frozen, I would recommend thawing the fruit and draining any excess liquid off. Frozen fruit will likely create more liquid at the bottom of the dish when baking.

You can use any mix of berries that you like, but the nutrition information will vary a bit.

Sweetener: We use and love Lakanto products. Use code THATLOWCARBLIFE for 20% off your order at Lakanto.

Xanthan Gum: This is a natural thickener used in many commercial products. A little goes a long way and it will last for years in your pantry. You can try this recipe without it, but you'll likely have a lot of liquid in the bottom of the dish.

  1. Hi,
    I would love be to make this for my July 4th BBQ, but am wanting to bake this in individual ramekins ,,,(the rest I’d put in a smaller baking dish). Would this work and how would you alter the baking time? Also, do you think I could sub sliced fresh strawberries for one of the berries? Oh, and I’ve tried your blackberry crisp and while I enjoyed it, I felt it was lacking sweetness (I like my berry crisp SWEET!). Woukd I be able to add additional sugar without turning this into a soupy mess? If course, I made your blackberry crisp in January, when berries weren’t at their ripest or sweetest, so that could have been my issue. Blackberries are also not the sweetest variety of berry, IMO.

      Hi Michelle!

      Sounds like the perfect 4th of July treat!

      I definitely think you could bake this in individual ramekins. The bake time might decrease a bit, but I’m not sure by how much.

      I think strawberries would likely work fine (though it will probably change the nutrition info a bit) and adding a bit more sweetener should also be fine – but you’re correct that blackberries aren’t super sweet on their own. I’d add the sugar called for and then taste and add a bit more until you get it where you want it.

      Hope that helps!
