Fall is my favorite season. When PSL (pumpkin spice latte) hits Starbucks, I decorate for fall, make all things pumpkin, and get my Christmas music on queue. Yes, I am that person you see wearing sweaters, even at 90 degrees, once the leaves have started to change.

One of our favorite mid-week sweet treats is Rice Krispie Treats. We love them, and you can’t beat our recipe!

I made a batch of my Churro Rice Krispie treats and loved them, so I just simply replaced the cinnamon and sugar combination with pumpkin spice, and it worked out beautifully!

What makes this treat so special is that you may personalize it by varying the amount of pumpkin pie spice used. I propose using the suggested quantity in the recipe as a starting point and then fine-tuning from there.

Tips for making this recipe!

Salted butter makes all the difference – that touch of salt is subtle but it enhances the flavor of these bars.

Instead of completely melting the marshmallows, we leave it a little lumpy. That way, there are plenty of pockets of ooey-gooeyness in the bars.

The recipe makes enough for nine dessert bars, just the perfect amount so you don’t overindulge.

Tips for storing rice krispie treats.

  • If you can resist eating them all in one sitting, follow these tips so they stay fresh and delicious:
  • To prevent the bars from sticking to each other, separate each one with wax paper. This is helpful if you stack them in a container.
  • Be sure to use an airtight container. If the bars are exposed to air, they will harden and dry out.
  • Rice Krispie Treats will keep well for up to three days at room temperature.

    These are so easy to make and perfect for an autumn party! After I stirred all the cereal in, I added 1/2 cup of dried cranberries and stirred quickly to combine. Everyone thought these treats were yummy!
