INGREDIENTS

1 cup unsalted butter, softened
1 cup brown sugar
½ cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
2 ½ cups all-purpose flour
1 teaspoon baking soda
½ teaspoon salt
1 cup semi-sweet chocolate chips
1 cup red and green M&Ms
½ cup crushed pretzels
½ cup toffee bits
¼ cup holiday sprinkles

DIRECTIONS

Step No.1: Cream the butter and sugars
In a large bowl, beat softened butter, brown sugar, and granulated sugar until light and fluffy, about 2–3 minutes.

Step No.2: Add the wet ingredients
Beat in eggs one at a time, followed by vanilla extract. Mix until fully combined and smooth.

Step No.3: Mix the dry ingredients
In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet mixture and mix until just combined.

Step No.4: Fold in the mix-ins
Gently fold in chocolate chips, M&Ms, crushed pretzels, toffee bits, and sprinkles until evenly distributed throughout the dough.

Step No.5: Chill the dough
Cover the bowl and refrigerate the cookie dough for at least 30 minutes. This helps prevent spreading and enhances flavour.

Step No.6: Bake the cookies
Preheat oven to 350°F (175°C). Scoop dough onto parchment-lined baking sheets and bake for 10–12 minutes until edges are golden.

Step No.7: Cool and enjoy
Let cookies cool on the pan for 5 minutes before transferring to a wire rack. Serve warm or store once fully cooled.

TIPS FOR SUCCESS

Chill the dough: Refrigerating the dough helps the cookies keep their shape and enhances their chewy texture.

Use parchment paper: This prevents sticking and ensures evenly baked bottoms for perfectly round, golden cookies.

Don’t overbake: Take cookies out when edges are golden—centres will finish baking as they cool for a perfect texture.

Balance the mix-ins: Avoid adding too much of one ingredient to maintain a balanced texture and consistent baking.

Customize for fun: Let kids choose their own mix-ins for a playful and personalised christmas cookie-making experience.

Scoop evenly: Use a cookie scoop for even portions, ensuring consistent baking and picture-perfect results every time.

Cool on wire rack: Letting cookies cool properly on a rack avoids soggy bottoms and keeps them crisp around the edges.

VARIATIONS

White chocolate version: Swap out semi-sweet chocolate chips for white chocolate to create a sweeter, more wintery cookie flavour.

Minty twist: Add crushed candy canes or mint chips for a cool, refreshing taste that feels extra festive.

Nutty crunch: Toss in chopped pecans or walnuts for added crunch and a nutty twist to balance the sweetness.

gluten-free diet option: Use a 1:1 gluten-free flour substitute to make these cookies suitable for gluten-sensitive guests.

Red velvet base: Add a touch of cocoa powder and red food colouring for a vibrant red cookie with holiday flair.

Dried fruit addition: Cranberries or chopped dried cherries add chewiness and a tart contrast to the sweet and salty mix.

Spiced up version: Mix in cinnamon or a pinch of nutmeg for warm, seasonal flavour that pairs perfectly with the sweet ingredients.

FAQ

Can I freeze the cookie dough?

Yes! Scoop dough into balls and freeze. Bake straight from frozen, adding 1–2 minutes to the baking time.

Can I use leftover Halloween or Easter candy?

Definitely. This recipe is great for using up any seasonal candy—just chop and toss them in like other mix-ins.

What if I don’t have toffee bits?

You can skip them or replace with crushed caramel candy, chopped nuts, or extra chocolate chips for a similar texture.

Can I use margarine instead of butter?

For best flavour and texture, stick with butter. Margarine may alter the cookie’s richness and structure.

Do I need to flatten the cookies before baking?

No need. They will spread naturally in the oven if properly chilled beforehand.
