🔪 How to Make Keto Berry Crumble
Preheat your oven to 375°F. Add the berries, sweetener, xanthan gum, lemon juice and zest in a large mixing bowl.
Tip: The combination of the lemon juice, natural juices from the berries and xanthan gum will make a wonderful sauce for the crumble.
Toss to combine, then pour the mixture into a buttered casserole baking dish.
Tip: Alternatively, you can also pour the mixture into ramekins to make individual portions. Then just add the crumble topping over the berries and bake.
In another mixing bowl, add in the almond flour, chopped pecans, cinnamon and nutmeg.
Tip: If you don't have pecans on hand, you can substitute with chopped walnuts instead.
Whisk to combine, then add in the brown sweetener and melted butter, then mix until well combined.
Bake for 30 minutes, then increase the temperature to 425°F and bake for an additional 5 minutes or until the topping is crisp.
Tip: If the crumble topping starts to brown too quickly, lightly tent it with aluminum foil and finish baking until the juices from the berries start to bubble around the edges.
Allow to cool slightly before serving with a scoop of your favorite Keto vanilla ice cream or whip cream.
Tips for Making the Best Keto Berry Crisp
- Shop for berries on sale. Fruit, when not in season, can be a little pricey. 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 than 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:
- Blueberries- 9 net carbs
- Strawberries- 5 net carbs
- Blackberries- 3.5 net carbs
- Raspberries- 3 net carbs
What is the Difference Between a Crumble and a Cobbler?
A cobbler is made with a biscuit type dough, where a crumble is made with a streusel topping.
What is the Difference Between a Crisp and a Cobbler?
A crisp is made with a streusel topping that includes oats, where a cobbler is made with a biscuit type dough.
What is the Difference Between a Crumble and a Crisp?
A crisp and a crumble topping are identical, with one exception- a crisp also includes oats, which of course isn't Keto friendly.
What is Crumble Topping Made of?
Crumble topping has some type of flour, butter and sweetener, and typically also includes flavorings like cinnamon and/or nutmeg.
How Do you Know When a Crumble is Done?
You will know it's ready when the berries have given up their juices and it starts to bubble around the edges.
How Many Carbs are in a Blackberry Cobbler?
Store bought blackberry cobbler contains about 43 grams of carbs, making it off limits for Keto. However, there are only 4 net carbs for a serving of this Keto Blackberry Cobbler and it's every bit as tasty as the traditional version!

This looks amazing and I’m sure it’s delicious too.
Keto Cooking Christian
It really is. I love the combination of flavors and textures in this crumble.
Lynn
Had a bag of mixed mango, papaya and added black berries and strawberries to get the amount of fruit I needed. Husband loved it. Super easy and very yummy
Keto Cooking Christian
That sounds amazing. I will have to try adding mango.
Robbi Allen
Delicious! Used blackberries 4 1/2 cups, pecans. added a handful of steel cut oats & handful of nsweetened large coconut flakes. All else as written. I am gathering ingredients to make again tonight - this time with with rhubarb. Great recipe!
Keto Cooking Christian
The great thing about this recipe is you can change it up as you like. I wouldn't recommend oats since this recipe is written for those following a low carb diet, but if it works for you, have at it! 🙂
PumpkinSpice
Providence helped me find you. searching Keto crumble on yt and there you were! I am new to the faith and you are a blessing.
Keto Cooking Christian
Thank you so much for your kind words! I'm thrilled that you found my blog and hope that my recipes and scriptures will be helpful to you.
Charlotte E
I’ll bet this is delicious and so easy, too.
Keto Cooking Christian
Thanks so much, it couldn't be easier and it is super tasty!
Keto Cooking Christian
You are so welcome! I am so happy you enjoyed it.
Lori McChesney
Can you help me, my best friend Marnie has to have gluten free recipes and she can’t have any nuts and she’s allergic to it ?
Keto Cooking Christian
She can just omit the pecans in this recipe. The topping won't be as crunchy, but will still taste delicious!
Ilze Hattingh
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!
Renecha R
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!
Rali
What's the serving size?
Debe
What size baking dish? 8x8 or 13x9?
Keto Cooking Christian
8" should work just fine!
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
Keto Cooking Christian
Hi Jill,
I actually don't have the nutrition facts by weight, only by the number of servings, sorry. I hope you enjoy it 🙂
