❤️ Why you'll love this recipe
If you're a fan of monster cookies, you're going to absolutely love this ice cream! If you've never had a monster cookie before, but you like peanut butter, M&Ms, chocolate chips, and oatmeal cookies, trust me that this ice cream is for you.
It's an easy ice cream to make as it has a pretty simple custard base and then a whole bunch of mix-ins.
Monster cookie ice cream is perfect for anyone who likes a lot of candy in their ice cream and it's great for birthday parties or as a special dessert.
The ingredients for this ice cream are pretty simple! Here's everything you need (but be sure to view the recipe card at the bottom of this post for ingredient amounts and full recipe instructions):
- Whole milk
- Granulated sugar
- Large egg yolks
- Heavy cream
- Vanilla extract
- Creamy peanut butter
- Crumbled oatmeal cookies
- M&Ms (plain or peanut butter or a combination- or the candy-coated chocolate pieces of your choice)
- Chocolate chips
The first time I made the ice cream, I tried to make a toasted oat ice cream, but the oats ended up really chewy once combined with the ice cream base.
I then tried infusing the ice cream base with oats, but it didn't really give me that oatmeal cookie flavor. So, I ultimately decided to use crumbled oatmeal cookies instead and use the oats as a pretty topping.
You can either use store-bought or bake your own oatmeal cookies.
🍦 How to make monster cookie ice cream
Have you ever made homemade ice cream before? If so, this recipe will be super easy for you! It's a standard custard-based ice cream that's very easy to make.
You will need an ice cream maker to process the ice cream. I have the KitchenAid ice cream attachment and highly recommend it.
To start, heat milk, sugar, and salt in a medium saucepan over medium heat.
Stir constantly, until the mixture just reaches the point of simmer. Remove from heat.
In a separate medium heat-proof bowl, lightly whisk the egg yolks.
Pour about half of the warm milk into the bowl with the egg yolks, whisking while you do so.
This is called tempering the egg yolks. You're introducing the hot mixture to them slowly, so they don't cook and scramble.
Now, pour the egg/milk mixture back into the saucepan with the rest of the milk.
Cook mixture over low heat, stirring constantly, until it thickens enough to coat the back of the spoon.
If you're using a thermometer, you'll want it to be between 170-180 degrees Fahrenheit.
Pour the heavy cream into a separate large bowl.
Strain the egg/milk mixture into the heavy cream and stir to combine. Stir in the vanilla extract. I use a lot because I want a delicious vanilla ice cream base to mix all my add-ins to.
Cover with plastic wrap and place in the fridge for at least 4 hours.
Once mixture has been sufficiently chilled, process in ice cream maker according to manufacturer’s directions.
While ice cream is processing, soften the peanut butter slightly by warming it up for a few seconds in the microwave. You want it to be easily spoonable but not liquid- this will make it easier to swirl into the ice cream.
When the ice cream is almost done hardening, mix in peanut butter in spoonfuls, crumbled oatmeal cookies, M&Ms, and chocolate chips.
Scoop ice cream in airtight containers- I highly recommend these ice cream containers (I have at least one in my freezer at all times!).
Place in the freezer for another 4+ hours, but ideally overnight.
Yes, the waiting is the hardest part. But it's so worth it!
And then you're ready to serve your monster cookie ice cream in bowls as large as you want.
You can also top the ice cream with more M&Ms, chocolate chips, and oatmeal cookie crumbles or oats. A peanut butter sauce would be delicious, too.
But even if you don't use any toppings, this ice cream is FULLY loaded with deliciousness!
Is there anything better than an ice cream absolutely packed with candy, chocolate, peanut butter, and cookies? The best part is that with every single bite, you get some combination of these delicious ingredients.
And don't worry, the delicious vanilla notes still come through in the ice cream base.
The only ice cream I want to eat from now on is the kind that's fully loaded with goodies.
⏲️ How to store
When stored properly in an airtight container, your monster cookie ice cream should stay fresh in your freezer for about a month.
Just make sure the container top is on tightly so your ice cream doesn't get freezer burn.
🎉 Variations on recipe
Though this recipe has all the elements of monster cookies, there are lots of things you can add to it to suit it even more to your tastes. Here are some fun ideas:
- Cookies of your choice: If you're not a fan of oatmeal cookies, use chocolate chip cookies, sugar cookies, or your favorite cookies (you could even use monster cookie dough pieces for a totally meta ice cream)
- M&M flavor of your choice: I love making this with a mixture of regular M&Ms and peanut butter M&Ms, but you can use any flavor you want
- Nuts: If you like extra crunch, consider adding almonds, walnuts, or pecans
- Crushed pretzels: Pretzels add a nice salty crunch
- Mini marshmallows: These add more sweetness and a chewy texture
- White chocolate chips: If you want a little more sweetness
- Toffee bits: These add a caramel-like crunch
- Coconut flakes: For tropical flavor and chewiness.
- Sprinkles: Because sprinkles always go with ice cream
- Chocolate fudge sauce, marshmallow sauce, caramel sauce, or peanut butter sauce: Add the sauce topping of your choice
- Whipped cream: Because it always makes a delicious ice cream topping
