Why you'll love it

Homemade milkshakes are so much fun to make, for kids and adults alike. They're indulgent, quick to make, and so fresh—not to mention a tasty way to cool down on a super hot day.
Make the Easy Blueberry Sauce using fresh blueberries (picked yourself, perhaps!) or even frozen berries. The sauce comes together in minutes and can be made in advance. (It's also delicious on pancakes and sundaes!)
And don't worry if you don't have a campfire: you can toast the marshmallows right in your kitchen! You can thread marshmallows onto metal skewers and place them under the broiler in your oven. If you don't have metal skewers place rows of marshmallows on a parchment paper-lined baking sheet.
You can also hold a marshmallow on a skewer over a gas or electric stove burner to brown it. And, if you're lucky enough to own a mini brulée torch then you can torch those 'mallows!

🔪 How to make a Toasted Marshmallow Blueberry Milkshake
Step 1: Make the blueberry sauce

Simmer blueberries, sugar and lemon juice in a saucepan and cook the sauce for about five minutes until it has thickened. Cool the sauce and then refrigerate it until it's nice and cold! Find the complete instructions for Blueberry Sauce at this link.
Step 2: Toast the marshmallows

Thread marshmallows onto metal skewers and place them on a parchment paper-lined baking sheet. Place them under the broiler and watch them closely! They take less than a minute to get golden brown.
Step 3: Make the milkshakes

Put the blueberry sauce and toasted marshmallows into a blender along with vanilla ice cream and milk. Blend until the mixture is smooth and frothy. Pour the mixture into chilled glasses, add a reusable straw, and enjoy!

Tips:
- Be sure that the Blueberry Sauce is cool or cold so it won't melt your ice cream. Better yet, make it a day or two before and have it waiting in the fridge.
- Under a broiler the marshmallows will brown very quickly. I learned the hard way that you have to stay right by the oven—if you walk away or get distracted they will burn! Fortunately you'll only be waiting less than 30 seconds and they'll be perfectly toasted.
- Not surprisingly, the marshmallows get sticky after they're toasted. Parchment paper on the baking sheet makes it much easier to remove them.

Make the milkshakes:

Notes
- Under a broiler, the marshmallows will brown very quickly. I learned the hard way that you have to stay right by the oven - if you walk away or get distracted they will burn! Fortunately, you'll only be waiting less than 30 seconds and they'll be perfectly toasted.
- There are lots of ways to toast marshmallows! Thread marshmallows onto metal skewers and place them under the broiler in your oven. If you don't have metal skewers place rows of marshmallows on a parchment paper-lined baking sheet. You can also hold a marshmallow on a skewer over a gas or electric stove burner to brown it. If you have a hot coal or gas grill either of those would work. And, if you're lucky enough to own a mini brulée torch then you can torch those 'mallows!
