Ingredients You’ll Need

Every ingredient in this recipe is straightforward but plays a critical role in the final taste, texture, and that beautiful golden color you’re after. From the creamy butter that adds richness to the fresh marshmallows that bring gooey sweetness, each component comes together to create the perfect balance.

¾ cup salted butter: Adds a savory richness that perfectly balances the sweetness and helps melt the marshmallows smoothly.
20 oz mini marshmallows (two bags minus 2 cups reserved): Provides that iconic gooey texture and a soft chewiness that holds everything together.
1 Tbsp vanilla extract: Enhances the flavor depth with a warm, inviting aroma and subtle sweetness.
12 cups Rice Krispies cereal: The crunchy backbone of this treat, offering lightness and crispiness in every bite.

How to Make Easy Rice Krispie Treats (Jumbo Size)

Step 1: Prepare Your Pan

Begin by spraying a 9×11 inch baking pan with nonstick cooking spray. This is a small step but essential to ensure your jumbo treats don’t stick, making serving and cleanup a breeze later on.

Step 2: Melt the Butter and Marshmallows

Grab your largest pot because our jumbo recipe needs space! Melt ¾ cup of salted butter over medium heat. Once melted, add nearly all the mini marshmallows—save 2 cups for the end—and stir gently as they melt into a luscious, glossy mixture. Keep a close eye as this happens; the marshmallows can burn if unattended, so patience here pays off wonderfully.

Step 3: Stir in Vanilla Extract

Take the pot off the heat and mix in 1 tablespoon of vanilla extract. This little addition transforms the marshmallow base from simple to sensational with a fragrant lift that makes your kitchen smell divine.

Step 4: Add Cereal and Reserved Marshmallows

Add in the entire 12 cups of Rice Krispies cereal along with the 2 cups of reserved mini marshmallows. This is why the huge pot is necessary—plenty of room to carefully fold everything together without squashing the crunch. Gently stir until every crisp is richly coated in the marshmallow goo.

Step 5: Transfer and Press Into the Pan

Scoop the mixture into your prepared pan. Lightly spray a silicone spatula with nonstick spray and spread the mixture evenly. Press according to your texture preference: lightly if you want a fluffier treat or firmly for tighter, denser bars—the choice is yours for the perfect jumbo bite.

Step 6: Chill and Slice

Cover the pan with plastic wrap and let the treats set on the counter or in the fridge for at least an hour. Chilling overnight is my top recommendation to achieve clean slice lines and a perfect firm texture. Slice into 12 or 24 large pieces depending on your serving plan, and you’re all set!

How to Serve Easy Rice Krispie Treats (Jumbo Size)

Garnishes

You can keep it classic or fancy these jumbo treats up with quick garnishes. A light dusting of powdered sugar, a drizzle of melted chocolate, or a sprinkle of colorful mini chocolate chips or sprinkles add just the right pop of visual and textural excitement.

Side Dishes

Pair these jumbo treats with a cold glass of milk for a nostalgic combo or serve alongside fresh fruit to balance the sweetness. They also play well with a scoop of vanilla ice cream for a fun twist on dessert night.

Creative Ways to Present

Want to impress at your next party? Cut the jumbo treats into festive shapes with cookie cutters, stack them as mini dessert towers, or wrap individual squares in parchment and tie with a cute ribbon. The size makes them a standout on any dessert table.

Make Ahead and Storage

Storing Leftovers

Keep any leftovers fresh by storing them in an airtight container at room temperature. They will maintain their chewy, crispy texture for up to 3 days, making them perfect for snacking throughout the week.

Freezing

You can also freeze the Easy Rice Krispie Treats (Jumbo Size) for longer storage. Wrap each treat tightly in plastic wrap and place them in a freezer bag. They’ll keep well for up to 6 weeks. Thaw at room temperature before enjoying.

Reheating

These treats are best enjoyed as is, but if you want to bring back that just-made softness, microwave a single treat for 10 to 15 seconds. It will become delightfully gooey again without losing its structure.

FAQs

Can I use regular-sized marshmallows instead of mini ones?

Absolutely! Just use the same total volume equivalent. Mini marshmallows melt faster, but regular ones will work just fine—just be sure to give them a bit more time to melt fully without burning.

Can I add mix-ins to the Easy Rice Krispie Treats (Jumbo Size)?

Of course! Chocolate chips, nuts, or even candy pieces can be folded in after mixing the cereal. Just be gentle so the treats stay fluffy and don’t get too dense.

What if I want smaller treats instead of jumbo ones?

This recipe is flexible! Slice into more pieces for smaller portions. The preparation remains the same; only the serving size changes.

Can I make these treats gluten-free?

Yes, as long as you use a gluten-free version of Rice Krispies cereal, these treats can be enjoyed by those avoiding gluten.

Why do I need to reserve 2 cups of marshmallows?

Adding those extra marshmallows at the end helps create pockets of gooey fun throughout the treats, adding a delightful contrast to the crispy cereal.

Final Thoughts

If you want a treat that’s quick to make, utterly delicious, and fun to present, this recipe is exactly what you need.

Cereal

12 cups Rice Krispies cereal

Instructions

Prepare the Pan: Spray a 9×11 inch baking pan with nonstick cooking spray and set aside to ensure the treats don’t stick after cooling.
Melt Butter and Marshmallows: In a large pot, melt ¾ cup salted butter over medium heat. Add almost all the mini marshmallows (about two bags), leaving 2 cups of marshmallows out for later. Stir gently to combine.

Transfer to Pan: Scoop the mixture into the prepared pan. Lightly coat a silicone spatula with nonstick spray and use it to spread the mixture evenly.
Press the Treats: For softer treats, press mixture lightly into the pan. For denser, thicker treats, press firmly. This controls texture according to preference.
