Most desserts are loaded with refined sugar. It can be tough to find low sugar dessert, but this dish is perfect!

Blueberries and other berries like strawberries and raspberries have a lot less natural sugar than most desserts. This has always astonished me because I love berries so much! They are perfect to use when you’re in the mood for a sweet treat.

What’s the Difference Between Crisp, Crumble, and Cobbler

Crumbles have a topping similar to streusel, often made with butter, flour, and sugar. A crisp is made very similarly, but often includes oats. Both often have the option to add nuts to the topping as well.

A cobbler is usually made with biscuit dough or pie crust. It has buttery, flaky layers with fruit filling lying within. Peach cobbler has always been one of my favorite desserts.

Fresh or Frozen Blueberries

You can use fresh or frozen berries in this recipe and the bake time will remain the same. I typically use fresh.

How to Make Healthy Blueberry Crisp

1. Preheat oven to 350 degrees.
2. Add blueberries, cinnamon, vanilla, sweetener, and lemon juice to a mixing bowl. Stir.
3. Mix the cornstarch and water in a small bowl. Add to the bowl and stir.
4. Transfer the blueberry mixture to the bottom of the baking dish.
5. Combine the oats, brown sweetener, cinnamon, and melted butter in a separate bowl.
6. Spread the topping throughout the pan.
7. Bake for 25-30 minutes.

What Sweetener to Use

The two biggest things that make this dish healthy is the use of rolled oats instead of all purpose flour and the sweeteners used instead of refined sugar.

I like to use granular monkfruit sweetener for the filling and granular golden monkfruit sweetener for the topping. Monkfruit is zero calorie, zero carb, and is made without the use of artificial sweeteners

You can also use the following: 

• Regular sugar (you can use the same amount outlined in the recipe)
• Pure Organic Maple Syrup (1/3 cup in the filling and 3 tablespoons in the topping)
• Honey (1/3 cup in the filling and 4 tablespoons in the topping)

What to Substitute for Butter

You can substitute melted coconut oil (best option) or olive oil.

How to Keep the Dish From Getting Watery

The filling will need a thickening agent to keep it from getting watery. I like to use a mix of cornstarch and water.

How Long Will it Last in the Fridge

Store the crisp in the fridge tightly sealed for 3-4 days.

Freezer Tips

Freeze the dish covered and tightly sealed. Thaw completely and bake for 20-30 minutes on 350 degrees.

I like to serve this with a nice scoop of vanilla ice cream. Rebel and Halo Top are my favorite brands that are sugar free.
