Wendy's Thin Mints Frosty Recipe

Wendy's Thin Mints Frosty was a chocolate or vanilla Frosty with a Thin Mints-flavoured sauce swirled in, sold for a limited time from 21 February 2025. To copy it, blend two cups of vanilla ice cream with half a cup of milk until thick, and swirl in a sauce of chocolate syrup, a few drops of peppermint extract and four crushed Thin Mints.

What the Thin Mints Frosty was

Food Network reported in January 2025 that Wendy's had teamed up with the Girl Scouts. From Friday 21 February 2025, for a limited time, either Frosty, chocolate or vanilla, could be ordered with a drizzle of Thin Mints-flavoured sauce swirled into the cup.

The Frosty itself was among the first five items on Wendy's menu. By Wikipedia's account its founder, Dave Thomas, wanted it thick enough to need a spoon, and the consistency lies between a milkshake and soft serve. The recipe below is a reconstruction, and MakeFoodLovely is not connected with Wendy's or the Girl Scouts.

Ingredients

• For the Thin Mints sauce:
• 3 tablespoons chocolate syrup
• 1/8 teaspoon pure peppermint extract
• 4 Thin Mint cookies, finely crushed
• For the Frosty:
• 2 cups vanilla ice cream
• 1/2 cup whole milk
• 1 tablespoon unsweetened cocoa powder

Instructions

1. Stir the chocolate syrup, the peppermint extract and the crushed cookies together in a small bowl.
2. Blend the ice cream, milk and cocoa in a blender on low speed for 20 to 30 seconds, stopping once to push the ice cream down, until smooth and very thick. A spoon should stand up in it.
3. Spoon a third of the Frosty into each of two cold glasses and drizzle it with sauce. Repeat twice, finishing with sauce on top, and drag a spoon through once to swirl.

A Frosty is only lightly chocolate

The same article says the first Frosty combined chocolate and vanilla, because Thomas thought a pure chocolate flavour would overwhelm the hamburgers. That is why the card adds one tablespoon of cocoa to vanilla ice cream and no more. For a vanilla Frosty, leave the cocoa out.

The plain version, with the texture explained at more length, is the Wendy's Frosty on this site.

Peppermint by the drop

Peppermint extract is strong. An eighth of a teaspoon is enough for three tablespoons of syrup. Measure it with a spoon; do not pour it from the bottle.

Crush the cookies finely, in a bag under a rolling pin. In a sauce that is drizzled, large pieces block the spoon.

Which cookies, out of season

Girl Scout cookies are sold for part of the year only. Any chocolate-coated mint cookie can stand in, and the homemade Thin Mints on this site can be made at any time.

When it comes out too thin

A Frosty that pours has been blended too long or with ice cream that was already soft. Put the blender jar in the freezer for 15 minutes and blend again for a few seconds. Start with ice cream straight from the freezer and milk straight from the refrigerator.
