Ingredients
- Two sticks unsalted butter: softened for richness and tenderness Use good quality butter for the best flavor
- Two thirds cup granulated sugar: provides sweetness and helps with the cookie's crisp edges
- One large egg yolk: binds the dough and adds moisture for a soft crumb
- One teaspoon pure vanilla extract: adds warm, sweet aroma and depth
- Two cups all purpose flour: gives structure and a classic cookie texture Choose fresh flour for best results
- Quarter teaspoon salt: balances sweetness and enhances the flavors
- Two cups powdered sugar: for a smooth, sweet frosting
- Three tablespoons whole milk: thins the frosting just enough for spreading or piping
- Two tablespoons unsalted butter: softened makes the frosting creamy and smooth
- Half teaspoon pure vanilla extract: for additional flavor in the frosting
- Green food coloring gel: for that vibrant Grinch green color Use gel for intense color without diluting frosting
- Red heart sprinkles: add the festive signature touch reminiscent of the Grinch’s heart
Instructions
- Cream the Butter and Sugar:
- Beat the softened unsalted butter together with granulated sugar in a large bowl for about two to three minutes until the mixture is light, fluffy, and pale. This aeration helps create tender cookies with a delicate crumb.
- Add Egg Yolk and Vanilla:
- Mix one large egg yolk and pure vanilla extract into the butter and sugar blend, stirring thoroughly so the batter is smooth and evenly combined without streaks.
- Incorporate Dry Ingredients:
- Gradually add the all purpose flour and salt to the wet mixture, stirring gently just until the dough comes together. Avoid overmixing to keep the cookies soft rather than tough or dense.
- Shape and Chill Dough:
- Roll the dough into one inch balls and arrange them on a baking sheet lined with parchment paper, spaced about two inches apart. Place the tray in the refrigerator and chill for about thirty minutes. Chilling firm dough prevents spreading and helps maintain the perfect thumbprint shape.
- Make Thumbprints and Bake:
- Preheat your oven to 350 degrees Fahrenheit or 175 degrees Celsius. Use your thumb or the back of a rounded teaspoon to gently press an indentation in the center of each dough ball. Bake for twelve to fourteen minutes or until the cookie edges show just a hint of golden color.
- Cool the Cookies:
- Remove the cookies from the oven and let them cool on the baking sheet for five minutes to set. Then transfer them to a wire rack to cool completely before frosting. Fully cooled cookies ensure the frosting stays in place.
- Prepare the Grinch Green Frosting:
- Beat powdered sugar, whole milk, softened butter, and vanilla extract together until smooth and creamy. Slowly add green gel food coloring and mix until you achieve a vibrant, festive green color perfect for the Grinch theme.
- Fill Thumbprints and Decorate:
- Spoon or pipe a generous amount of green frosting into the center indentation of each cookie. While the frosting is still soft, gently press one red heart sprinkle in the middle to create the iconic Grinch heart look.

My favorite ingredient here is the green gel food coloring because the intensity transforms the frosting into that unmistakable Grinch green that sparks joy every time I bake these. These cookies remind me of a holiday baking session I shared with my niece where frosting the cookies together ended in green fingertips and lots of laughter.
Storage Tips
Store these cookies layered with parchment paper between them in an airtight container at room temperature. They stay fresh for up to five days without losing their tender texture or vibrant frosting. Avoid refrigerating as cold can alter the frosting's consistency and the cookie texture.
Ingredient Substitutions
You can swap unsalted butter for a plant based buttery spread to make the recipe vegan friendly without sacrificing flavor or texture. Instead of the egg yolk, use one tablespoon unsweetened applesauce to retain moisture and tenderness with a slight fruity note. If red heart sprinkles are unavailable try tiny dried cranberries or pipe small red dots of royal icing for a natural, homemade touch.
Serving Suggestions
Add a teaspoon of orange zest to the dough or frosting for a subtle citrus twist that brightens the flavor. Serve these cookies alongside warm drinks like hot chocolate, mulled cider, or spiced tea to create a cozy holiday treat spread. For holiday parties, experiment with different colors or festive sprinkles to make themed variations that delight guests.

These Grinch thumbprint cookies are a simple, festive treat that bring color and joy to any celebration. Enjoy baking and decorating them with family.
