Slow Cooker Berry Crumble

A delicious dessert that I love making in my slow cooker is Berry Crumble, made using all-purpose flour, quick-cooking oats, frozen blueberries, and frozen strawberries.

To make Berry Crumble in your slow cooker or crockpot, mix your dry ingredients and cut in the butter to create a crumbly texture. Layer the seasoned fruit in the cooker, top with the crumble, and cook on high for about 3 hours.

There’s something truly comforting about the aroma of Berry Crumble filling the house. It’s a simple pleasure that turns any ordinary day into a special occasion.

Can I Use Fresh Berries Instead of Frozen?

Yes, you can use fresh berries instead of frozen in this recipe. If you choose fresh berries, you might want to reduce the thickening agent, as fresh berries release less juice than frozen ones, which could affect the consistency of your crumble.

Slow Cooker Berry Crumble Ingredients

  • 3/4 cup all-purpose flour
  • 3/4 cup quick-cooking oats
  • 1/4 cup + 2 tablespoons Truvia Brown Sugar Blend
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 6 tablespoons unsalted butter, diced into small chunks
  • 1/2 cup mini chocolate chips (optional)
  • 3 cups frozen blueberries
  • 2 cups frozen strawberries
  • 1/4 cup Truvia Baking Blend
  • 1 tablespoon lemon juice
  • 2 tablespoons cornstarch

How To Make Slow Cooker Berry Crumble

  1. Prepare the crumble topping: In a large bowl, whisk together flour, oats, Truvia Brown Sugar Blend, cinnamon, and salt. Add the small chunks of butter and use a pastry cutter to blend until the mixture becomes crumbly. For a chocolatey twist, fold in the mini chocolate chips; set aside.
  2. Prepare the fruit mixture: Allow frozen fruit to thaw slightly at room temperature to release excess ice naturally. In a separate large bowl, combine the blueberries and strawberries with the Truvia Baking Blend, lemon juice, and cornstarch. Toss well to ensure all fruit is evenly coated.
  3. Assemble in the slow cooker: Spray the inside of a 5-7 quart slow cooker with nonstick cooking spray. Transfer the fruit mixture to the slow cooker, spreading it evenly. Gently pour the crumble topping over the fruit, making sure to cover all areas.
  4. Cook the crumble: Place a paper towel under the lid of the slow cooker to catch any condensation. Set the cooker to high and cook for approximately 2 1/2 to 3 hours. The crumble should be golden on top and the fruit mixture should be bubbly at the edges.
  5. Serve and enjoy: Spoon the warm berry crumble into bowls and serve with a scoop of low-sugar ice cream or a swirl of whipped topping for the perfect finishing touch.

Recipe Variations

  • Nut Mix-In: Add 1/2 cup of chopped walnuts or pecans to the crumble topping for a crunchy texture.
  • Spice It Up: Mix 1/4 teaspoon of nutmeg or allspice with the cinnamon for a deeper spice flavor.
  • Berry Variation: Use a mix of raspberries, blackberries, and cherries instead of just blueberries and strawberries.
  • Sugar Alternatives: Substitute the Truvia with an equal amount of coconut sugar or maple syrup if preferred.
  • Vegan Twist: Replace the butter with coconut oil and choose a vegan chocolate chip option to cater to vegan diets.

What If I Don’t Have Truvia?

If you don’t have Truvia, you can substitute it with equal amounts of granulated sugar, honey, or maple syrup. Keep in mind that these alternatives may slightly alter the flavor and nutritional content of your crumble.

How Do I Know When the Berry Crumble Is Done Cooking?

The Berry Crumble is done when the topping is golden and crisp, and you can see the fruit mixture bubbling around the edges.

This typically takes about 2 1/2 to 3 hours on high heat in your slow cooker. Ensure no powdery spots remain on the topping.

What To Serve With Berry Crumble

You can serve your delightful Berry Crumble with creamy sides like vanilla ice cream, whipped cream, and Greek yogurt. Lightly salted caramel sauce or warm custard also complements its flavors beautifully.

Or you can enjoy it with a cup of strong black coffee or a glass of dessert wine, enhancing the berry flavors.

How To Store Berry Crumble

In The Fridge:

Place the Berry Crumble in an airtight container to keep it fresh. I prefer to cover it with a tight lid to avoid absorbing other food smells. Itโ€™s best enjoyed within three to four days. Ensure it’s cool before refrigerating to maintain its texture.

In The Freezer:

Berry Crumble doesn’t freeze well due to the moisture content in the fruit. Freezing can make the topping soggy and the fruit too watery upon reheating. I suggest enjoying it fresh or storing it in the fridge instead.

How To Reheat Berry Crumble

Reheat your Berry Crumble by placing it in a 350ยฐF oven for about 10 minutes. If it’s in a microwave, heat it on high for a minute.

Cover with aluminum foil to keep the moisture in while reheating in the oven. This method helps maintain its delicious, crispy top.
