Ingredients You’ll Need
These ingredients are simple yet essential for balancing sweet, crunchy, and fruity flavors in your Blueberry Swirl Rice Krispies Treats Recipe. Each one plays a key role in creating the perfect texture and taste that makes this dessert irresistible.
- Rice Krispies cereal (6 cups): This forms the crispy, airy base that’s iconic to Rice Krispies treats.
- Marshmallows (1 package, 10 oz): The melty glue that binds everything together and delivers that chewy softness.
- Unsalted butter (3 tbsp): Adds richness and helps the marshmallows melt smoothly without burning.
- Blueberry preserves or jam (1/2 cup): The star ingredient for a sweet, tangy swirl that brightens up these treats.
- Vanilla extract (1/4 tsp): Enhances the overall flavor complexity with a warm, subtle note.
- Pinch of salt (optional): Balances sweetness and deepens flavor contrast.
- Fresh blueberries (1/2 cup, optional): Adds bursts of juicy texture and a fresh, vibrant feel to each bite.
How to Make Blueberry Swirl Rice Krispies Treats Recipe
Step 1: Prepare the Pan
Start by lining a 9×9-inch baking pan with parchment paper or lightly greasing it with butter or cooking spray. This simple step prevents sticking and makes clean-up a breeze after your treats set.
Step 2: Melt the Butter and Marshmallows
In a large pot over medium heat, melt the butter until it’s smooth and bubbling lightly. Then, add the marshmallows and stir continuously until they are completely melted and form a glossy, smooth mixture. Patience here is key to avoid burning and ensures the perfect consistency for binding.
Step 3: Add Rice Krispies Cereal
Remove the pot from heat immediately and fold in the Rice Krispies cereal, stirring gently but thoroughly to coat every crisp with the marshmallow mixture. This creates the classic chewy-crispy base of your treats.
Step 4: Prepare the Blueberry Swirl
Transfer the blueberry preserves into a microwave-safe bowl and heat for 20 to 30 seconds until it becomes a little thinner and easier to swirl. This heating step is crucial for achieving those beautiful, even ribbons throughout your treats.
Step 5: Swirl the Blueberry Jam
Pour about half of the Rice Krispies mixture into your prepared pan, pressing it down gently into an even layer. Drizzle half of the warmed blueberry preserves across the surface, then use a spoon or a knife to gently swirl the jam through the mixture. Repeat this layering and swirling with the remaining Rice Krispies mixture and blueberry preserves for a marbled, artistic effect.
Step 6: Top and Set
If you’re adding fresh blueberries, sprinkle them evenly over the top now. Then press everything down lightly one more time to set the layers together. Set the pan aside to cool and let these treats firm up at room temperature for about 30 minutes or until they can be cut cleanly.
How to Serve Blueberry Swirl Rice Krispies Treats Recipe

Garnishes
To take your Blueberry Swirl Rice Krispies Treats to the next level, consider topping with a handful of fresh blueberries or a light dusting of powdered sugar. The fresh fruit complements the preserve’s sweetness perfectly and adds a pretty finishing touch.
Side Dishes
These treats pair wonderfully with a glass of cold milk or a scoop of vanilla ice cream for dessert parties or casual family snacks. The creamy dairy balance enhances the sweet and tangy blueberry flavors while soothing the crunchy texture.
Creative Ways to Present
For a fun twist, cut the treats into bite-sized cubes and skewer with fresh berries or small mint leaves for a pretty party platter. You can also layer them in mason jars with yogurt and extra blueberry jam for a delightful layered dessert cup.
Make Ahead and Storage
Storing Leftovers
Store any leftover Blueberry Swirl Rice Krispies Treats in an airtight container at room temperature. They stay fresh and chewy for up to three days, making them perfect to prepare in advance for gatherings or snack times.
Freezing
To freeze, wrap individual servings tightly in plastic wrap and place them in an airtight freezer bag. When properly stored, they can last up to one month without losing their delicious texture or blueberry swirls.
Reheating
Although these treats are typically enjoyed at room temperature, if you prefer them a little softer, microwave a piece for about 10 seconds. This melts the marshmallow slightly and refreshes the chewy, gooey texture without compromising the blueberry swirl’s flavor.
FAQs
Can I use other types of cereal?
Absolutely! While Rice Krispies cereal delivers the classic texture, you can experiment with similar puffed rice cereals. Just keep in mind the texture and density might alter slightly.
Is fresh blueberry necessary?
Not at all! Fresh blueberries add an extra burst of texture and freshness, but the blueberry preserves alone create the signature swirl and flavor, so feel free to omit them if you prefer.
How do I get the blueberry preserves to swirl evenly?
Warming the preserves in the microwave first makes them more spreadable and easier to swirl evenly throughout the Rice Krispies mixture, giving that beautiful marbled effect.
Can I make this recipe gluten-free?
Yes. Ensure you use gluten-free Rice Krispies cereal, as some brands contain malt flavoring derived from barley. The rest of the ingredients are naturally gluten-free.
How long does it take for the treats to set?
About 30 minutes at room temperature is usually enough for the treats to firm up properly so they can be cut into neat squares without crumbling.
Final Thoughts
I can’t recommend enough giving the Blueberry Swirl Rice Krispies Treats Recipe a try—it’s a delightful way to elevate a classic snack with fresh, fruity flavors and gorgeous visual appeal.
