How to Make Halloween Sugar Cookies

Cream together the butter and sugar - Beat the softened unsalted butter until creamy. Beat in the packed brown sugar and the granulated sugar until blended well - about 3 to 5 minutes.

Beat in the egg - Beat in the egg and egg yolk as well as the vanilla extract until incorporated.

TIP: An egg separator is useful to separate the egg white from the egg yolk easily and without making a mess.

Combine the dry ingredients - In a separate bowl, combine the spooned and leveled flour together with the baking soda, cornstarch, and salt.

Blend the dry ingredients into the butter mixture - Slowly mix the flour mixture into the sugar mixture until combined. It will be sticky.

Stir in the mix-ins- Using a spoon or mixer on low speed, stir in the 1 cup of Halloween M&M’s and Halloween sprinkles.

Scoop the cookie dough - Scoop the cookie dough into 1.5 tablespoon cookie balls (#40 cookie scoop) and place them in a covered container and chill the dough for at least 3 hours.

Prepare the oven and cookie sheets - Preheat the oven to 350ºF and line cookie sheets with parchment paper. Place the chilled cookie dough onto the sheets 2 inches apart.

Bake - Bake in the preheated oven for 11-12 minutes.

Remove and decorate - Remove the cookies from the oven and press additional M&M’s and sprinkles into the tops of each cookie.

Cool and store - Allow the cookies to cool for 10 minutes before transferring them to a cooling rack to cool completely. Store these M&M Halloween Sugar Cookies in an air-tight container for up to 3-5 days for maximum freshness.

Do I Have to Chill Cookie Dough?

It depends. For this particular cookie dough, yes, you do need to chill it. If this dough is not chilled, the cookies will spread way too much and the cookies will be ultra-thin and run into each other while baking.

If you're short on time (or patience!) these No Chill M&M Candies Cookies might be what you're looking for. Simply swap out the color of the M&M's to fit the theme or occasion.

Tips for Baking Halloween Sugar Cookies

Don't skip chilling the dough for these Halloween Sugar Cookies - The dough is very soft and sticky and baking the cookies without chilling will cause them to fail. Patience is key when making this recipe!

Keep the dough chilled - Bake these cookies one baking sheet at a time. After removing the cookie dough balls from the container and placing them on the cookie sheets, place them back in the refrigerator to chill while the sheet of cookies bakes. You want the dough to stay as cold as possible.

Can You Freeze Sugar Cookie Dough?

Yes, you can freeze this sugar cookie dough! This sugar cookie dough isn't for cookie cutter cookies as it does spread but using a cookie scoop to scoop the cookie dough into one and a half tablespoons of dough will make it easy to grab frozen cookie dough from the freezer and bake as many or as little as you want at any given time.

To bake the frozen sugar cookies, there is no need to remove the cookie dough from the freezer to allow it to thaw before baking. Simply preheat the oven add the frozen cookie dough balls to the baking sheet and bake for the time instructed in the recipe.

Frozen cookie dough stays good in the freezer when stored properly for 3 months.
