FAQs:

How many cups are in a box of Rice Krispies cereal?

• If you’re making a grocery list for our Rice Krispie Treat recipe, you might be wondering how many cups are in a Rice Krispie cereal box. Rice Krispies are sold by weight, so the volume of the cereal varies.  
• A single-serve box of Rice Krispie cereal weighs .88oz, equaling roughly 1/2 to 3/4 cup. 
• The small box of Rice Krispie cereal weighs 8 oz, which is about 6-8 cups. 
• A box of Rice Krispie cereal labeled as Large weighs 12oz, this is the most regular Rice Krispies cereal box and contains about 10 to 12 cups. 
• The Family Size box of Rice Krispie cereal weighs 18oz and contains about 15-18 cups. 
• The Mega box of Rice Krispies cereal weighs 25.2 oz, which is about 21-25 cups.

Why are my homemade Rice Krispies Treats hard?

• Your homemade Rice Krispie treats may turn out hard if you start with stale marshmallows or press them too firmly into the pan.

Can you make Rice Crispy treats with no butter?

• You can absolutely make classic Rice Krispies treats without butter. Just swap the butter in the Rice Krispie mixture for coconut oil or extra virgin olive oil. (Make sure it’s extra virgin so you won’t taste the olive oil at all. You can taste the coconut oil a bit, but it’s subtle and delicious!)

Supplies for Halloween Rice Krispies:

• Large pot
• Stirring spoon
• Nonstick 9×9 baking tin
• Spatula
• Small spatula or butter knife

Halloween Rice Krispie Treats

Ingredients for these fun Halloween treats:

• 1/4 cup butter
• 4 cups miniature marshmallows
• 6 cups Rice Krispies cerial
• Halloween Reese’s peanut butter cups
• Halloween sprinkles

Directions on how to make Festive Halloween Rice Krispie Treats:

1. Melt butter in a large pot over medium heat.

2. Once the butter is melted, add mini marshmallows to the pot.

3. Stir continually until the marshmallow mixture is smooth and creamy. Remove from heat immediately.

4. Pour the box of Rice Krispies Cereal into the pot, then stir and fold the mixture until the ingredients are evenly distributed.

5. Use a spatula to scrape the mixture out of the pot and into the baking tin.

6. Gently press the mixture into the pan with the spatula, and use your hand to fully flatten and smooth out the top.

7. Lightly coat the top with Halloween sprinkles. 

8. With a small spatula, make slits in the top and wiggle a small opening in the top. For this size pan, make three rows of three.

9. Press Halloween Reese’s into the openings with the small spatula.

10. Add round, orange sprinkles where the little bats and ghosts should have eyes.

11. Allow the treats to set for 2 hours at room temperature or 30 minutes in the refrigerator.

12. Cut into squares and serve.

Variations and substitutions:

• Use any type of puffed rice cereal in place of classic Rice Krispies.
• Mix in a cup of chocolate chips. (When I do, I use mini chocolate chips.)
• Add candy eyes or candy corn to your decorations.
• Melt candy melts and drizzle different colors over the top of your treats.

Tips and Tricks:

• Don’t press down too firmly at any point in the process. You could pack the treats too firmly, or you could mash the candy decorations.
• If you don’t have a nonstick pan handy, prepare your pan with nonstick cooking spray, parchment paper, or wax paper. 
• Store in an airtight container, or tightly covered with plastic wrap. They stay fresh for a couple of days and become firmer over time.

I love that I can run to a local grocery store, grab some affordable ingredients, and follow super simple steps to make festive treats during this busy time of year. I have costumes to make, trick-or-treat candy to buy, school events to help with, decorations to put up… This is the easiest way to whip up a yummy batch of individual-serving treats. 

These easy treats remain a go-to recipe for good reasons. Sweet, chewy, crunchy, individually portioned, handheld, no-bake… are there any cons at all? Halloween Reese’s make the perfect addition in both flavor and texture. They enhance the melt-in-your-mouth goodness, and classic peanut butter and chocolate flavors go perfectly with the marshmallow flavor.
