Craving blueberry pie but not the time, effort, or Points that go with baking a whole pie? This low-fat blueberry pie sundae gives you all the cozy, fruity flavor you love — but in a faster, lighter, single-serve format.

A quick stovetop blueberry sauce gets mixed with fresh berries, then spooned warm over cold vanilla frozen yogurt and topped with crumbled shortbread cookies. It’s sweet, juicy, and creamy with just the right amount of crunch.

This is one of my favorite summer-to-fall transition desserts — especially when fresh blueberries are plentiful. It tastes special, but comes together in minutes, which makes it perfect for weeknights, entertaining, or anytime you want a treat that satisfies without going overboard.

Ingredients & Substitutions

  • Water & cornstarch – Thickens the blueberry sauce.
  • Fresh blueberries, divided – Frozen blueberries may be substituted; don’t thaw first.
  • Sugar – Just enough to sweeten. Use less if your berries are very sweet. Substitute with your favorite non-calorie sweetener if you prefer.
  • Fresh lemon juice – Brightens and balances the flavor.
  • Ground cinnamon – Optional, but adds great warm gently spiced flavor.
  • Salt – Enhances flavor.
  • Low-fat vanilla frozen yogurt – Or swap nonfat Greek yogurt, light ice cream, dairy-free frozen dessert, or sugar-free ice cream.
  • English shortbread cookies, crumbled – Graham crackers, biscotti crumbs, or vanilla wafer crumbs also work nicely.

How to Make Easy Low Fat Blueberry Pie Sundaes

Step 1: Make blueberry sauce.

In a small bowl (affiliate link), whisk together 1 tablespoon water and cornstarch. In a small saucepan over medium heat, combine remaining 2 tablespoons water and 1-1/2 cups blueberries and bring to a boil. Reduce heat and allow to simmer for 3 minutes, or until berries start to break down. Gradually add cornstarch mixture to blueberry mixture, whisking constantly. Cook about 1 minute, or until slightly thickened.

Remove pan with blueberry mixture from heat and stir in remaining 3/4 cup blueberries, sugar, lemon juice, cinnamon and salt. Let blueberry mixture stand about 5 minutes.

Step 2: Make Sundaes

In six small bowls or dessert glasses, scoop 1/2 cup low fat vanilla frozen yogurt. Spoon approx. 1/3 cup blueberry mixture over each scoop frozen yogurt and sprinkle evenly with crumbled cookies.

Serve immediately.

Recipe Notes

The blueberry sauce can be made ahead and stored in an airtight container in the refrigerator. If refrigerated, just add to a microwave-safe bowl and heat on high for about 90 seconds, or until warm. Be sure to stop and stir the mixture every 30 seconds to prevent any burning.

Serving Suggestions

Serve in small bowls or parfait glasses with:

  • Fresh berries
  • A little extra cookie crumble
  • A sprig of mint
  • A dollop of whipped topping

For a fun twist, layer the yogurt, blueberries, and cookie crumbs into mini parfaits or assemble bite-size versions in mini phyllo cups.

      Not sure why it won’t freeze. We use commercially available frozen yogurt for this recipe. ~Martha
