    Giant Bake Sale Rice Krispies Treats Recipe (Video)

    Thick and spongy bake sale rice Krispies treats, made even better by stirring in extra mini marshmallows! Cut into large squares to serve or package for your next bake sale. A delicious snack that will go fast! I'm also sharing a list of other great bake sale treats! 

    These fruity pebble bars are a fun twist on this traditional treat!

    Years ago I helped out with a bake sale with the teenage girls at church to raise money for summer camp. We received so many generous donations from our congregation, and our fundraiser was a huge success! One of the girls' grandmother donated two large trays of rice krispies treats. We've all had them, right? So good, and so simple, and they really don't need any embellishments. HOWEVER, the ones she brought were thick, spongy, and so incredibly good. They were one of the first items to sell out and I made sure to buy one for my girls to share before they were all gone! These spongy, giant treats have changed my life---maybe that's an exaggeration. They definitely changed the way I make the iconic treats and are SO MUCH BETTER.

    What was the secret? Upon inspection I noticed that she stirred mini marshmallows into her mixture before patting them down in the pan. They add such a chewy and spongy texture! I've started making my own rice krispies treats like this and will never go back. They are always such a hit!

    Giant Bake Sale Rice Krispies Treats

    (scroll down for printable recipe)

    Ingredients

    • 8 Tbsp. butter (1 stick)*
    • 3 (10 oz. packages marshmallows)
    • 12 cups Rice Krispies cereal (1 12 oz. box)

    *if you watch my video you'll notice that it calls for 6 tablespoon of butter instead of 8. Either way works, but after making these over the years I'm a fan of using 8 Tbsp.

    How To Make the BEST Rice Krispies Treats

    • In a LARGE microwaveable bowl add butter and 2 packages of marshmallows*. Reserve the 3rd package for later.
    • Microwave in 45-second intervals, stirring in between with a wooden spoon or rubber spatula, until melted and gooey. Stir.
    • Place cereal in a large bowl or large pot. Pour melted marshmallow/butter over and stir until completely combined. Add the last package of mini marshmallows. Stir.
    • Pour mixture into a large prepared baking pan (lined with parchment or wax paper or sprayed with cooking spray. I use a 13×18″ jelly roll pan.) Spray your hands with nonstick cooking spray or grease with a small amount of butter and pack down really well.
    • Sprinkle with sprinkles and use your hands to pat down to make sure they stick.
    • Let stand until room temperature or chill until firm.
    • Cut into large squares.
    • Store in an airtight container or wrap individually.

    Stove top directions: heat butter and marshmallows in a large pot on medium to low heat until melted and smooth. Stir in cereal and mini marshmallows using a wooden spoon. Prepare the rest the same as above.

    Make a large batch of these for your next potluck, bake sale, or after-dinner treat! I like packaging them up and putting them in my kids' lunches. They'll go fast!

    How much should I sell the Rice Krispies treats for at a bake sale?

    I'd say these could easily go for $1.00. They are large, individually packaged, and are a great value. The key is making them stand out; by cutting them into large portions and adding sprinkles, you are making them stand out.

    Can I make these Rice Krispies treats ahead of time?

    You can make these a day before and wrap them to keep them fresh.

    What sells best at bake sales?

    Presentation is everything. We recently went to a dessert auction for our local scout troop. I brought jumbo chocolate chip cookies, individually wrapped, and placed in an inexpensive $2 basket. I made a quick label and wouldn't you know? That basket of cookies was auctioned off for $50 when plates of cookies next to it went for $10-$15. Were my cookies better? Probably not, but they were packaged to sell vs. set on a paper plate with plastic wrap.

    Jumbo treats:

    Large cupcakes, big cookies, jumbo Rice Krispies treats.

    Desserts dipped in chocolate:

    Chocolate strawberries, chocolate dipped marshmallows, chocolate dipped cookies. These looks fancy and will go quickly as well.

    Desserts on a stick:

    These are easy to carry and kids LOVE them! Marshmallows on a stick (dipped in chocolate), cake pops, etc.

      How thick are these since using a cookie sheet pan? Looks yummy .
      Also, have you ever tried browning the butter? If I brown the butter, should I add in more butter to replenish the butter that evaporated? I’m guessing yes.. ok, gonna try your recipe .

        They are the thickness of the pan and then some, haha. It fill the pan to the top and a bit over, so just as thick as the ones made in a 9x13. This is basically a double batch of regular treats with an added bag of marshmallows. I haven’t made these with brown butter but I’d agree with your assumption to maybe use a little more.

        Hi Mary! When we sold these at a girls camp fundraiser we wrapped them in plastic wrap. It wasn't cutesy, but it worked well! I hope that helps!

        It made about 18 4"x3" treats. Just adjust to get more or less 🙂

      This looks real good but I'm confused about the amount of marshmallows. Is that three TEN ounce bags of marshmallows?

        Hi Tasha! YES! 3 (10 oz. bags). It looks like my new recipe plug-in is getting confused a bit. Thanks for letting me know! I've updated it 🙂
