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.

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!!

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

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 or 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 us 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 adda 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 1/2 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
