This quick and easy take on berry crisp comes together in about 5 minutes using everyday ingredients and your microwave (affiliate link). It’s the perfect way to satisfy a sweet craving without turning on the oven! While I used frozen blackberries as the base, feel free to swap in your favorite frozen berries or a mixed berry blend—whatever you have on hand works beautifully.
I don’t know about you, but when I hear berry crisp, I immediately think dessert. And yes—this makes a warm, delicious single-serve blackberry dessert. But here’s the best part: with just under 150 calories, it’s light enough to enjoy any time of day. I especially love spooning it over plain nonfat Greek yogurt for a decadent, yet healthy, breakfast! that feels like a treat.
Ingredients
- Frozen blackberries – Naturally sweet (affiliate link) and bursting with juicy flavor, frozen blackberries are a convenient and nutritious fruit option. They soften beautifully in the microwave (affiliate link), creating a warm, jammy base for your quick crisp.
- Non-calorie sweetener – A little boost of sweetness without the added sugar or calories. Choose your favorite no-calorie option—like stevia, monk fruit, or a sugar substitute you trust—to keep this treat WW-friendly and guilt-free.
- Cornstarch – Just a pinch thickens the berry juices into a luscious sauce, giving your crisp that cozy, cobbler-like texture you crave.
- Crunchy Oats & Honey Granola Bar – The secret to a speedy crisp topping! Crushed and sprinkled on top, this grab-and-go granola bar adds just the right amount of crunch and flavor with minimal effort.

How to Make Single-Serving Blackberry Crisp
Step 1: Gather and prepare all ingredients.
Step 2: Add the frozen berries to a small microwavable bowl. Stir in the sweetener and cornstarch until combined.
Step 3: Cover bowl with paper towel and microwave on HIGH for 1 minute. Check to see if berries are completely thawed, if not, continue microwaving on HIGH in 30 second increments until hot. (Mine were done after 2 total minutes.)
Step 4: Remove from microwave and stir berries and sauce. Top with crush granola bar.
Step 5: Before serving, top with dollop of lite whipped topping or scoop of low-fat vanilla ice cream or frozen yogurt, if desired.
Recipe Notes, Variations & Substitutions
I usually prefer fresh blackberries, but for this easy crisp recipe you’ll definitely want to use unsweetened frozen blackberries. The frozen berries will release more juice than fresh berries while cooking in the microwave, creating a lightly sweetened sauce for this dessert crisp.
No frozen blackberries? Try using any unsweetened frozen blueberries or raspberries in place of the blackberries, or a combination of your favorites.
Gluten free? If you have a gluten sensitivity, you can easily make this gluten-free by substituting your favorite gluten-free granola bar.
No granola bar? Substitute your favorite low-fat crunchy granola for the crushed granola bar.
Serving Suggestions
Enjoy this simple dessert plain, with a dollop of lite whipped topping, or a scoop of low-fat vanilla ice cream or frozen yogurt.
Serve over 1/2 cup plain nonfat Greek yogurt for a decadent breakfast!
