Pumpkin pie Rice Krispie treats are such a fun treat for Thanksgiving. They are perfect for classroom parties, or to just up the cuteness factor on your dessert table.
Spray two pie pans with nonstick spray and set aside.
Melt the ½ cup butter in a large pot over medium-low heat. If desired, add the 1 teaspoon pumpkin pie spice.
Add the 10 oz marshmallows and continue to stir until they are completely melted. Then, turn off the heat.
Start by adding a couple of drops of orange food coloring. Stir until incorporated. Continue to add the food coloring a drop or two at a time until the color resembles pumpkin pie.
Add the 6 cups Rice Krispie cereal and stir to coat.
Press into the prepared pans and spread. Use a measuring cup with the bottom sprayed with non stick cooking spray to flatten the Rice Krispies evenly.
Let cool until set, about one hour. Then invert onto a cutting board and cut into 8 wedges like you would cut a pie. (Alternatively, you can cut them in the pan.)
In a medium sized mixing bowl, beat the softened ½ cup butter until lump free.
Add the 1½ cups powdered sugar and 1 teaspoon vanilla extract, beating until fully incorporated. Add just enough milk or water to make it smooth, the beat until light and fluffy.
Use about ⅓ of frosting to pipe a dollop of frosting onto each slice to look like whipped cream on a piece of pie.
Either whip in ¼ cup creamy peanut butter or a drop of brown food coloring to tint the remaining frosting for the crust. Pipe in a zigzag line or tight swirls around the edge to look like the crust.
These rice krispie treats can be stored in an airtight container at room temperature. They taste best within three days of being made.
Notes
You can also melt the butter and marshmallows in a large glass bowl in the microwave. Just use short bursts until everything is melted and you can stir it smooth.For pumpkin pie bars, press the mixture into a greased 9x13-inch pan and just dollop a generous amount of white buttercream "whipped cream" onto the center of each square.
