directions

Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
In a large mixing bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.
Add eggs one at a time, beating well after each addition, then mix in vanilla extract.
Gradually add the dry ingredients into the wet mixture until just combined.
Stir in oats, chocolate chips, M&Ms, pretzels, toffee bits, and sprinkles.
Scoop dough onto prepared baking sheets using a cookie scoop, spacing about 2 inches apart.
Bake for 10–12 minutes or until the edges are lightly golden. The centers will look soft but will firm up as they cool.
Allow cookies to cool on the pan for 5 minutes before transferring to a wire rack.

FAQs

How do I keep kitchen sink cookies from spreading too much?

Chilling the dough for 30 minutes before baking helps prevent excessive spreading.

Can I make the dough ahead of time?

Yes, the dough can be refrigerated for up to 3 days or frozen for up to 3 months.

Do I need to toast the pretzels before adding?

No toasting needed—just crush and mix them in for that salty crunch.

Can I use quick oats instead of rolled oats?

Yes, but rolled oats give a chewier texture. Quick oats will work in a pinch.

Are these cookies good for mailing?

Absolutely! They hold up well and travel nicely when packed securely.

Can I substitute other candies for the M&Ms?

Definitely. Try chopped peppermint bark, mini peanut butter cups, or any seasonal candy.

What kind of sprinkles work best?

Use jimmies or confetti sprinkles. Nonpareils can melt or bleed color.

Can I make them dairy-free?

Yes, use dairy-free butter and chocolate chips.

How do I make the cookies thicker?

Use slightly less sugar and chill the dough before baking to help them stay thick.

What makes these cookies “Christmas” themed?

The festive red and green M&Ms, sprinkles, and holiday mix-ins give them that seasonal flair.
