Easy one pot cookies bars with light and fluffy milk buttercream to leave for the big guy! Mr. Claus (and everyone else) is going to love these Milk and Cookie Bars (for Santa!).

This Milk and Cookie Bars (for Santa!) post is sponsored by Dairy Farmers of Canada. My Kitchen Love has been compensated monetarily. I only work with brands I love and cook with at home.
Christmas is literally right around the corner and with it come preparations for traditions and small gestures that make the holidays, well just that, the holidays.
For my family, we have the festive tradition of putting out milk and cookies for Santa on Christmas Eve. These Milk and Cookie Bars are our new way to make sure Santa hits our house.
While making these one of my daughters actually refused to try them at first because she insisted that they and all the milk be left for Santa Claus (completely intact … all 20 bars!!).
She doesn’t want to risk upsetting Santa one little bit.
There’s always a carton of milk in the house during the holidays, Canadian milk is delicious and refreshing. A familiar household taste that peaks during the holiday season.
It’s traditions and special moments like leaving some milk and cookies out for Santa that resonates deeply with me and will continue on with my own children for many years to come.
From baking to waiting for Santa, there’s milk for holiday necessities and everyday needs.
Holiday traditions vary from family to family, although milk is often found at the heart of Christmas traditions. One tends to leave cookies AND milk.
Plus, we’ve got hot chocolate happening on the regular for those cold days that need more cozy vibes.
Our other holiday traditions include these Butterscotch Peanut Butter Marshmallow Squares and while not a baking item, I’m still obsessed with this Pomegranate-Mint Relish for Christmas Dinner.
Here’s an adorable holiday video from my friends with Dairy Farmers of Canada:
