1. Prepare the Cookies

1. Preheat your oven to 375°F (190°C). This ensures an even bake.
2. In a large mixing bowl, combine the cake mix, oil, and eggs. Stir until the mixture is just combined—overmixing can result in tough cookies.
3. Scoop spoonfuls of dough onto a parchment-lined baking sheet, spacing them evenly.
4. Bake for 9 minutes. Keep an eye on them; slightly underbaked cookies retain a soft, chewy texture.
5. Let the cookies cool completely on a wire rack before moving on to the frosting.

2. Prepare the Frosting

1. In a mixing bowl, whip the butter at medium speed for about 8 minutes until it’s light and fluffy. This step is key to achieving a silky-smooth texture.
2. Add the salt, peppermint extract, heavy cream, and 2 cups of powdered sugar. Start mixing on low speed for 1 minute to avoid a sugar cloud, then increase to medium speed for 3 minutes.
3. Gradually incorporate the remaining powdered sugar. Mix on low for 1 minute, then on medium for 5 minutes, until the frosting is smooth and creamy.

3. Assemble the Cookies

1. Spread a generous layer of frosting on each cooled cookie. Don’t skimp—this is where the peppermint magic happens!
2. Sprinkle crushed candy canes over the frosted cookies. They not only add a festive look but also a delightful crunch and burst of minty flavor.
