- 6 cups Rice Krispies cereal: The essential crispy base that delivers that beloved light crunch in every bite.
- 1 package (10 oz) marshmallows: The glue that holds everything together with gooey sweetness and softness.
- 3 tbsp unsalted butter: Adds richness and helps melt the marshmallows for easy mixing.
- 1/2 cup blueberry preserves or blueberry jam: The star ingredient for that gorgeous, fruity swirl full of flavor and color.
- 1/4 tsp vanilla extract: Beautifies the flavor profile with a warm, fragrant hint.

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 give it a light butter or cooking spray coat. This simple step ensures your treats will lift right out without sticking and keeps clean-up quick and easy.
Step 2: Melt the Butter and Marshmallows
In a large pot over medium heat, melt the butter until it’s completely liquid and warm. Then add the marshmallows and stir gently but continuously until they melt down into a smooth, glossy mixture—this is the golden glue binding your treats together.
Step 3: Add Rice Krispies
Once your marshmallow mixture is smooth, remove the pot from heat right away. Stir in the Rice Krispies cereal until every little crispy piece is evenly coated. This step ensures that each bite has that classic chewy crunch you know and love.
Step 4: Prepare the Blueberry Swirl
Transfer your blueberry preserves to a small microwave-safe bowl and heat for about 20-30 seconds. This softens the jam, making it easy to drizzle and swirl beautifully throughout the cereal mixture.
Step 5: Swirl the Blueberry Jam
Pour half of your coated Rice Krispies mixture into the prepared pan and press it gently into an even layer. Drizzle over some of that warm, spreadable blueberry preserves, then swirl the jam into the cereal layer using a spoon or knife to create a marbled look that’s as pretty as it is delicious.
Step 6: Top and Set
Add the remaining Rice Krispies mixture on top, pressing it down gently to form a smooth layer. Drizzle and swirl the rest of the blueberry preserves again and, if you’re using fresh blueberries, sprinkle them across the top for an extra burst of juicy flavor and appealing texture.
Step 7: Let Set
Allow your Blueberry Swirl Rice Krispies Treats to cool at room temperature for about 30 minutes. This resting time helps them firm up nicely so you can cut clean squares without them falling apart.
Step 8: Serve and Enjoy
Once set, slice your treats into squares, serve, and prepare to be delighted by the perfect mix of gooey, crunchy, and fruity goodness. These treats are ready to brighten up any occasion!
How to Serve Blueberry Swirl Rice Krispies Treats Recipe

Garnishes
Top your treats with a dusting of powdered sugar or scatter a few extra fresh blueberries over the top for a beautiful, eye-catching display. A small drizzle of melted white chocolate can add a decadent touch that complements the blueberry swirl perfectly.
Side Dishes
This Blueberry Swirl Rice Krispies Treats Recipe pairs wonderfully with a simple glass of cold milk or a scoop of vanilla ice cream for a fun dessert pairing. They also make a sweet counterbalance alongside a fresh fruit salad or a tangy yogurt dip.
Creative Ways to Present
Try cutting these treats into fun shapes using cookie cutters for parties or kids’ lunches. You can also layer crumbled treats over yogurt parfaits or serve them alongside tea or coffee for a delightful snack break.
Make Ahead and Storage
Storing Leftovers
Store your treats in an airtight container at room temperature to keep them nice and chewy. They’re best eaten within 2-3 days but can last up to a week if stored correctly without drying out.
Freezing
If you want to make these ahead of time, they freeze beautifully. Wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container. When you’re ready, just thaw at room temperature for an hour or so and enjoy.
Reheating
Reheating is generally not necessary for these treats, but if you prefer them softer, a few seconds in the microwave can warm them up just enough without melting the blueberry swirl or changing the texture dramatically.
FAQs
Can I use frozen blueberries instead of fresh?
Yes, you can! Just make sure to thaw and drain them well to avoid extra moisture, which can make your treats soggy.
What if I don’t have blueberry preserves? Can I use another flavor?
Absolutely! While the blueberry swirl is the highlight here, you can experiment with strawberry, raspberry, or even cherry preserves for a similar fruity effect.
Is there a way to make these treats gluten-free?
Definitely! Ensure you use gluten-free Rice Krispies cereal (or an alternative puffed rice cereal) to keep this recipe gluten-free without sacrificing flavor or texture.
Can I add nuts or seeds for extra crunch?
Yes, tossing in some chopped nuts or seeds can be a fantastic addition. Just mix them in with the cereal after it’s coated in marshmallow for best results.
How do I get the perfect swirl pattern with the blueberry preserves?
Warm the preserves slightly to make them more spreadable, then drizzle generously before swirling gently with a knife or spoon. Avoid over-mixing to keep that beautiful marbled effect.
