I bake the cookies for 12-14 minutes. They are done when the bottoms are just lightly golden and the tops are set but still pale. They should not brown on top. I learned the hard way that overbaking makes them crunchy instead of tender. I let them cool on the baking sheet for exactly 5 minutes—they are too fragile to move when hot. Then, while they are still warm but firm enough to handle, I roll each one generously in the reserved cup of powdered sugar in my shallow bowl. I let them cool completely on a wire rack, and then, for that classic snowy look, I give them a second roll in the powdered sugar. This double coat ensures a beautiful, thick, snowy exterior.
Pro Tips for Best Results
The temperature of your dough is everything. If your kitchen is warm, chill the rolled dough balls on the baking sheet for 15 minutes before baking. This prevents them from spreading and helps them keep their perfect round shape. I’ve tried this both ways, and the chill time is the secret to plump, pretty snowballs.
For the most vibrant mint flavor without any bitterness, use a high-quality pure peppermint extract. If you only have mint extract (which is often a blend of spearmint and peppermint), start with 3/4 teaspoon, as it can have a sharper, almost toothpaste-like taste. The vanilla extract is essential for rounding out the flavor, making it taste like a gourmet candy rather than just pure mint.
When rolling the baked cookies in powdered sugar, do the first roll while they are still quite warm. The residual heat helps the sugar adhere and creates a slightly melted glaze. The second roll, once completely cool, gives you that flawless, dry, snowy finish. Sifting your powdered sugar for rolling prevents any little lumps from sticking to the cookies.
Common Mistakes to Avoid
My first batch turned out flat and greasy because my butter was too soft. I took “softened” to mean “almost melted.” Your butter should be cool—you should be able to make an indent with your finger, but the stick should still hold its shape. If it’s oily or shiny, it’s too warm. Pop it back in the fridge for 10 minutes if you’re unsure.(See the next page below to continue…)
