Light as a dream, this Toffee Marshmallow Pie has an easy no-bake filling that everyone will love. You only need 6 ingredients, and it’s a great pie to make ahead of time.
This pie would be perfect for your Thanksgiving dessert, but would also be a great dessert year round!

I really like a wide variety of pies on Thanksgiving. Rich pumpkin pie, fruity lemon meringue, and of course something chocolate. But it’s always nice to throw in something that is a little bit lighter, as well. (Ok, not lighter as in calories lighter… I don’t want to confuse you here!) This pie is exactly that.
This couldn’t be much easier, either. It’s a no-bake filling, (the only time you’ll need the oven is to bake your pie crust), and it can be made well ahead of time. And it has everyone’s favorite – toffee!
This is one of those pies that you don’t think will work when you look at the ingredients, but it comes out perfect for me every time. And I never have leftovers because everyone loves it!

Ingredients
- Marshmallows: This can get a little confusing, because there are so many sizes of marshmallows these days. I’m using the regular large marshmallows, not the big roasting marshmallows. I have only ever tried this with the large marshmallows, but if you are using small marshmallows, you should need about 240 grams of marshmallows.
- Milk: I suggest sticking with 2% or whole milk here.
- Toffee Pieces: I use the Heath Bits o’ Brittle pieces. They are not covered with chocolate. I am sure there are other brands, but this is the easiest to find for me. I can usually find them the grocery store, but you can also order them online.
- Heavy Whipping Cream: You’ll be making whipped cream, so makes sure this is heavy whipping cream.
- Pie Crust: You need one fully baked pie crust. I like to use a homemade pie crust, but use what you like.
- Hot Fudge: This is optional, for serving, but I highly suggest it! You can make it homemade or use a store bought jar.

How to Make Toffee Marshmallow Pie
STEP 1: Melt the marshmallows and milk in a large saucepan. You want to stir this constantly over medium heat until the marshmallows are melted.
STEP 2: Remove the pot from the heat and add in the toffee pieces. Give it a quick stir, then let the mixture sit for a couple minutes to let the toffee melt slightly.

STEP 3: Stir the mixture again quickly, then transfer the pot to the refrigerator and let the mixture sit until thickened, but not set, about 15-20 minutes.
STEP 4: While the mixture is thickening up, place the cream in a large bowl. Whip until you have stiff peaks.

STEP 5: Remove the marshmallow toffee mixture from the refrigerator. Stir about 1/4 of the cream into the mixture, then gently fold in the remaining cream.
STEP 6: Transfer the filling to your baked pie crust. Cover and refrigerate until the filling is completely set, about 3 hours.

Tips and Tricks
We like this served with hot fudge and additional toffee pieces. It’s actually quite delicious without adding anything, but the chocolate and toffee take it over the top.
This pie can easily be made the day before. Just keep covered until ready to serve.
I had a reader wanting to substitute mini chocolate chips for the toffee pieces. While I haven’t tried it, it should work, but will change the flavor and texture of the pie.

I am not a marshmallow person at all, but I decided to give this a try for our potluck lunch at work and maybe Thanksgiving tomorrow. I made two last night. One is already gone and it’s barely 7:30am. My coworkers think I’m a cheffin genious! Thanks!
Deborah says
yay! I’m so glad they loved them!
Dina says

Oh my! This looks like a true delight! 🙂 I have a thing for marshmallows….I will be making this, and possibly a version with a graham crust, and chocolate in/or drizzled on top. S’more style.

That pie looks amazing. And I love marshmallows! Funny you referenced the PB Best of the Bakeoff book. I was just at the PB Bakeoff 2 weeks ago in Vegas (part of why I couldn’t meet that deadline). Beautiful pie & pinned!

Beautiful pie, Deborah! Love the sound of toffee and marshmallows together!

Just gorgeous, and I love the simplicity! You can’t beat a no-bake filling, especially around Thanksgiving when you’re already baking so many other recipes.

Colleen @ What's Baking in the Barbershop?! says
What a unique method! I’ve never made a marshmallow pie like this, but it sounds pretty simple! And I love that it’s “lighter,” at least in texture 😉 On Thanksgiving, nobody counts calories anyway 🙂
