    Are you ready for a sweet treat that is easy to make and oh so delicious? This crumble has a mix of blackberries, raspberries and blueberries.

    Mixed Berry Crumble - Keto, Low Carb & Gluten Free

    Ripe and juicy berries are topped with mixture of almond, pecans, cinnamon, nutmeg and butter, sweetened with Brown Swerve, then baked to perfection, filling your home a mouth-watering fruity and nutty aroma!

    If you haven't tried Brown Swerve yet, you should! It looks, feels and tastes just like real brown sugar, but has zero carbs and zero guilt!!

    Mixed Berry Crumble - Keto, Low Carb & Gluten Free

    The inspiration for this delectable gluten free dessert comes from my love of cobblers and fruit crumbles in my pre-Keto days!

    So, when I found some really amazing blueberries at my grocery store, I just had to put them to good use.

    Mixed Berry Crumble - Keto, Low Carb & Gluten Free

    There're so many wonderful ways to incorporate berries into healthy Keto friendly desserts or treats. With just a few substitutions, this will become a dessert the whole family will enjoy, even those not following Keto.

    What's in Gluten Free Mixed Berry Crumble

    • Blackberries
    • Blueberries
    • Raspberries
    • Almond Flour
    • Swerve confectioners
    • Brown Swerve
    • Grass-fed Butter
    • Pecans
    • Lemon
    • Xanthan Gum
    • Ground cinnamon
    • Ground nutmeg
    • *Optional: homemade whip cream for the top

    *Exact measurements are listed in the recipe card below.

    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

    INGREDIENTS

    For the Berries

    • 2 cups blackberries
    • ½ cup fresh blueberries
    • 1 cup fresh raspberries
    • 3 tablespoons  monk fruit/allulose
    • Juice and zest of ½ lemon
    • ¼ teaspoon Xanthan Gum

    For the Crumb Topping

    • 1 cup super fine almond flour
    • ⅓ cup pecans, chopped
    • ¼ cup grass fed butter, melted
    • ¼ cup Brown Swerve
    • ½ teaspoon ground cinnamon
    • ¼ teaspoon ground nutmeg

    INSTRUCTIONS

    • Preheat oven to 375°F.  Mix the swerve and Xanthan gum in a cup, then set aside.
    • Add the berries, lemon juice and zest to a large bowl.  Sprinkle the sweetener and xanthan gum over the top and toss until well coated.  Pour the mixture into a buttered glass or ceramic baking dish.
    • In a separate bowl, add all the crumble topping ingredients, except for the brown sweetener and butter, then whisk.  Mix in the brown sweetener and melted butter. Sprinkle the crumble over the top of the berries.
    • Bake for 30 minutes, then increase the temperature to 425°F and bake for an additional 5 minutes or until the crumble is crisp.  Allow to cool slightly before serving with a scoop of Keto Vanilla Ice Cream or whip cream on tpp.

    RECIPE NOTES

    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.
    For the berry filling,  you don't have monk fruit/allulose blend on hand, you can use monk fruit or Swerve instead.  
    For the streusel crumble topping, try to stick to using the Swerve Brown, because though I typically prefer the brown monk fruit/allulose blend, it won't crisp up as well.
    If you don't have pecans on hand, you can substitute with chopped walnuts instead.

      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 🙂

      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.

          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.

      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!

      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!

      Could you substitute apples for the berries? What adjustments would need to be made?

        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/

      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!

        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 🙂

      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.

      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

        The Xanthan Gum acts as a thickener for the juices from the berries and lemon.

      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.
      .
