In honor of the 7th annual Austin Ice Cream Festival, which I am helping produce this Saturday, I decided to make another batch of homemade ice cream. While rice krispie treats have never been my favorite treat (no chocolate), it surprises me that no one makes a rice krispie treat ice cream (to my knowledge). I donned my mad scientist chef’s hat and gave it a whirl.
What you’ll need:
- 1 1/3 cup mini marshmallows
- 1 1/2 cup puffed rice cereal
- 1 Tbsp butter
- 2 cups milk
- 4 tsp cornstarch
- 1 1/4 cup heavy cream
- 2 Tbsp light corn syrup
- 1/4 tsp kosher salt
- 1 jar marshmallow creme
First, make a small portion of rice krispie treats: In a small bowl, melt the butter in the microwave. Add 1 cup of marshmallows and microwave until melted, about 45 seconds. Mix well. Stir in cereal. Spread onto a sheet of wax paper using a buttered spatula.
Next, make the ice cream: In a small bowl, stir together 1/4 cup milk and the cornstarch; set aside. In a saucepan (3 quarts is plenty big), whisk together the remaining milk, 1 1/4 cups cream, sugar, corn syrup, and salt; bring to a boil over medium-high heat. Cook for 4 minutes; stir in milk-cornstarch mixture. Return to a boil and cook, stirring, until thickened, about 2 minutes. Remove from the heat. Add the marshmallow creme and stir until completely melted. Pour the mixture into a large plastic bag; seal, and submerge in a bowl of ice water until chilled. You can also refrigerate it in the container of your choice, however using a bag in and ice bath is the fastest cooling method.
Once cool, pour the mixture and 1/3 cup of marshmallows into your ice cream maker and mix per the manufacturer’s instructions. I had it in my KitchenAid Ice Cream Maker Attachment on the stir speed for 20 minutes. While the ice cream is churning, break your rice krispie treats into small pieces. After the ice cream has finished churning, stir in the rice krispie pieces. Transfer the soft ice cream to a storage container and freeze until set, at least 2 hours.
I hope to see you at the Ice Cream Festival tomorrow!
