We doubled down on the peanut butter flavor in these absolutely delicious Peanut Butter Cup Rice Krispie Treats. First, we added just the right amount of peanut butter to our original Rice Krispie Treat recipe and then upped the ante by folding in chunks of Reese’s Peanut Butter Cups.  Something this easy to make should not be so yummy to eat.  We hope you love this recipe as much as our family did!

All the ingredients you will need to make Peanut Butter Cup Rice Krispie Treats.

How to Make the Marshmallow Mixture

Step 1: Melt the butter in a large saucepan on medium-low heat.
Step 2: Add the Mini Marshmallows to the melted butter. Stir the marshmallows so they are completely covered in butter.
Step 3: On medium-low heat, stir the marshmallows continually until they are completely melted. When the marshmallows are melted, take the pan off the heat.

Adding the Peanut Butter and the Rice Krispies Cereal

Steps 6-7: Add the Rice Krispies cereal to the peanut butter mixture. Fold together until the cereal is covered in the peanut butter marshmallow mixture.

Step 8: Do this step the night before you make the treats! Rough chop the Miniature Reese’s Peanut Butter Cups and then put them in the freezer for 3-4 hours or overnight. Do not skip this step or the peanut butter cup pieces will melt into the warm Rice Krispie Treat mixture when you add them.
Step 9: Add the frozen Peanut Butter Cup pieces into the pan.
Step 10: Fold the pieces into the Rice Krispie Treat mixture.

Assembly Instructions

Step 13: Place the 1/4 cup of chocolate chips into a plastic bag and melt in the microwave. Cut off a corner of the plastic bag, and drizzle the melted chocolate onto the treats.
Step 14: Place the 1/4 cup of peanut butter into a plastic bag and melt in the microwave. Not too much, you just want the peanut butter to be warm enough so you can drizzle it over the pan of treats. Cut off a corner of the plastic bag, and drizzle the peanut butter onto the treats.
Step 15: Allow the chocolate and peanut butter drizzle to cool

Serving/Storage Instructions

Rice Krispie Treats will last 2-3 days at room temperature in an air-tight container before they start to get stale.  You can extend that timeline a few days if you store them in the refrigerator and then take them out about 30 minutes before you eat them.  They freeze up great though and that is what we do if we want to make these ahead of time for a party or a family gathering.  They defrost very quickly and taste great once they are defrosted.  You can keep them in the freezer for up to a couple of months.
