How to Make the Recipe
-
Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper.
-
Mix Dry Ingredients: In a bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
-
Cream Butter and Sugars: In a large mixing bowl, beat the softened unsalted butter, granulated sugar, and brown sugar until creamy and fluffy.
-
Add Egg and Vanilla: Mix in the egg and vanilla extract until well combined.
-
Incorporate Dry Ingredients: Gradually add in the dry mixture and mix until just combined. Don’t overmix!
-
Add Food Coloring: Divide the dough into portions and add different colors of food coloring to each. Knead gently to incorporate color.
-
Shape the Cookies: Use cookie cutters to cut shapes. Place them on the prepared baking sheet, leaving some room between each cookie.
-
Bake: Bake for about 10-12 minutes, or until the edges are lightly golden. The centers will look slightly underbaked; that’s okay!
-
Cool: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
-
Decorate: Once cooled, add edible glitter or sprinkles, and watch them sparkle!
Pro Tips for Making the Recipe
- Softening Butter: If you forget to take your butter out of the fridge, you can cut it into small cubes and let it sit at room temperature for 15 minutes.
- Dough Chilling: For firmer cookies, chill the dough for 30 minutes before cutting into shapes.
- Avoid Overbaking: Keep an eye on the cookies; they should be soft in the center when you take them out.
- Use Quality Food Coloring: Gel food coloring gives more vibrant colors compared to liquid versions.
- Mix in Flavors: Feel free to add mini chocolate chips or nuts for extra flavor!
How to Serve
These cookies shine on their own but can also be served on a beautiful platter at parties. Pair them with a glass of cold milk or a scoop of your favorite ice cream for a fun dessert.
Make Ahead and Storage
- Fridge Storage: Store your cookies in an airtight container at room temperature for up to a week.
- Freezing: You can freeze the cookie dough before baking. Just scoop it into balls, freeze them, and once solid, transfer to a freezer bag. They can be baked directly from frozen, just add an extra minute or two to the baking time.
- Reheating Tips: If you want to enjoy them warm, pop in the microwave for a few seconds or in a preheated oven at 350°F for about 5 minutes.
