How to Make Keto Berry Crumble
For the Berries
Preheat your oven to 375F.
Mix the Swerve confectioners and xanthan gum in a cup, then set aside.
Add the berries, lemon juice and zest to a large bowl.
Sprinkle the Swerve mixture over the top and toss until well coated.
Pour the mixture into a buttered glass or ceramic baking dish.
For the Gluten Free Streusel Topping
In a separate bowl, add all the crumble topping ingredients, except for the Swerve Brown and butter, and give it a good whisk, breaking up any large lumps.
Don't worry about the smaller lumps because it will all bake together and will give it that streusel like texture.
Mix in the Swerve Brown and melted butter.
Sprinkle the crumble over the top of the berries.
Bake for 30 minutes. Increase the temperature to 425F and bake for an additional 5 minutes or until the crumble is crisp.
Allow to cool slightly before serving!
Tips for Making the Best Keto Berry Crisp
- Shop for berries on sale. Fruit, when not in season, can be a little pricy. Shopping for locally harvested berries at fruit stands or farmer's markets are sometimes where you'll find the best berries and they are usually less expensive then the grocery store.
- If you can't find fresh berries in season, you can use frozen. Berries that are frozen are picked at peak season so they're a great substitute. When making a Keto crumble or crisp with frozen berries, you will need to add a few additional minutes to the cooking time to allow the extra moisture to cook out.
- Because berries become juicier when they are cooked, using a thickener like the one used in this recipe, xanthan gum, will give the crumble a nice thick and glistening sauce like consistency, so don't skip that ingredient.
- Keep an eye out for the top turning too brown. You don't want to shorten the cooking time to ensure the crumble is cooked through so if the top begins to turn too brown, cover with a little aluminum foil until it finishes baking.
- Even in season berries can be a little too tart sometimes so taste them before you mix them up. Add a little more sweetener if need needed, it won't hurt a thing
Are Berries Keto?
Berries are allowed on Keto in moderation because out of most all other fruit, berries are the lowest in sugar. And they're very nutritious. There're an excellent source of antioxidants and are high in fiber. To read more about the health benefits of berries, read this article from Healthline.
What are the Carbs in Berries?
The carbs in berries vary depending on the type. Here're the most commonly used berries in Keto desserts and approximate net carbs per ½ cup serving:
- Carbs in Blueberries- 9 net g of carbs
- Carbs in Strawberries- 5 net g of carbs
- Carbs in Blackberries- 3.5 net g of carbs
- Carbs in Raspberries- 3 net g of carbs
Serve with a scoop of your favorite low carb ice cream or a nice dollop of homemade whip cream.

Lovely, wholesome and flavorful taste! I used a frozen berry mix (strawberries/cherries/blueberries) and added 1/2 tsp salt to the crumble topping, which is really needed. This is a keeper 🙂
Keto Cooking Christian
Thanks so much! I am so glad you enjoyed it. I love keeping this recipe handy for when I need a quick dessert for last minute guests. Thanks for the comments. 😊
Carri
I just made this and haven't tried it yet. Taking it to a Christian church home group meeting so I can have something keto to eat. They do pot lucks every week. I didn't have blackberries so I subbed for strawberries.
Keto Cooking Christian
I hope you enjoy it! Let me know how the strawberries work out.
Carri
It was delicious! Not sure if it was the strawberries or not, but there was a little tartness with the sweetness, which in my opinion, was perfect. I think everyone else liked it too being sugar free, gluten free and keto as we have a few peeps who are on restricted diets. There was only 1 serving left when I took it home, for which I was GLAD, because I was able to have ONE LAST dish of it! I also served it with whipped cream. I increased the recipe by 1 1/2. Definitely a KEEPER. Thank you! I'm gonna make this again soon.
Keto Cooking Christian
Thank you so much for these awesome comments and for the suggestion of the strawberries. I will have to try that for myself sometime.
Joy
This is a great recipe! It’s the recipe that got me addicted to Julianne’s take on keto! Thanks!!!
Keto Cooking Christian
Oh, this just makes my day. Thank you so much! I am so glad you enjoyed it.
Maureen
Made this last night for company and everyone loved it! I used 3.5 c of frozen mixed berries, which I mixed with the other filling ingredients. When I put this in a 9 x13” pan, it seemed a bit light on the berries, so I added about 1 cup of fresh blueberries. The results were fantastic! Thank you for the recipe. I’ve tried a number of keto berry desserts and have never found one I was thrilled with… until now!
Keto Cooking Christian
Thank you so much! I am thrilled you all enjoyed it. I love being able to use all the sweet summer time berries in this recipes.
Gail Snyderman
I absolutely love this dessert and so do my guests. I've changed a couple of things, though. Instead of two cups blackberries, I do one cup each of fresh blueberries, blackberries, raspberries and strawberries. Also, I do a half-cup of sweetener in the mix to sweeten up the berries. In the crust, , I double the cinnamon and the nutmeg for a little more flavor. It comes out perfect.....add a dollop of whipped cream, and everybody just loves it. Soooo easy, too. Thanks for this keeper!
Keto Cooking Christian
I am so glad you love it!
Mary
Could you substitute apples for the berries? What adjustments would need to be made?
Keto Cooking Christian
I would not use apples, since they are much higher in carbs than the berries. But I have a recipe using chayote squash that actually has the same texture and tastes like apples: https://ketocookingchristian.com/keto-mock-apple-crumble-low-carb-gluten-free/
Rebecca
I loooove this!!!!
Keto Cooking Christian
Awesome!
Clay
I have made this several times using Trader Joe’s frozen mixed berries. Absolutely love this crumble. The lemon is a perfect balance for the sweetness.
Keto Cooking Christian
That's awesome, glad you love it!

My husband calls me the “cobbler gobbler” and this satisfied my cobbler cravings. I made this several months ago. I shared it with some friends and they loved it. I didn’t care so much for the lemon, but it’s just a personal preference. I’m getting ready to make it again and will try it without. Thank you for sharing!
Keto Cooking Christian
Please tell your husband I love the "cobbler gobbler" that's so cute! The lemon is just to cut some of the sweetness, but you can certainly leave it out and it will still be great. Hope you enjoy it 🙂
Colleen
Made this tonight. Substituted frozen berry mix and added a bit more xantham gum. Topped it with whipped cream. Delicious. Thanks so much for the recipe.
Tara
I’m in the process of making the crumble part of this recipe and have omitted the xantham gum. Why is this used? I’ve also substituted rhubarb and raspberries for the berries you suggest as I have so much rhubarb in my garden. Fingers crossed it turns out as well as yours has for others. When you have time, please explain the necessity of xantham gum. Thx
Keto Cooking Christian
The Xanthan Gum acts as a thickener for the juices from the berries and lemon.
Christina Cox
Just made this tonight! It’s the best keto dessert I’ve had! Love everything about it - thank you so much!
Keto Cooking Christian
So glad you loved it and thanks for letting me know!

What's the serving size?

What size baking dish? 8x8 or 13x9?

Jill
I’m wondering how many serves in this crumble as the nutritional facts refer to date per serve but not the weight or number of serves. Would you have this i formation?
Incidentally I have the crumble in the oven to have for desert tonight. I’m looking forward to it.
.
Many thanks
