[feast_advanced_jump_to]Eggnog is one of those things you either love or hate, and I have always been firmly on team love. I first made these eggnog cookie bars in 2014. Because they are so good, I keep adding them to my holiday baking year after year.
For years, our boys would always finish the eggnog before I got to all my recipes. So, I learned to buy two cartons: one for them to drink and one for me to bake with.
As much as I love sugar cookies, there comes a point in December when rolling, cutting, and decorating is too much work. I used our extra eggnog to transform my unicorn sugar cookie bars into a one-pan holiday delight.
These cookie bars are soft, buttery, and have eggnog in the cookie base and the creamy frosting. Trust me, they are the perfect holiday dessert for parties. Even after all these years, they still get compliments every time I make them. And when my husband says a dessert is good, I know it's a keeper!
Why You'll Love Eggnog Cookie Bars
- Made in one pan. These cookies are baked and frosted in a 9x13 pan, so no rolling or cutting is necessary.
- Double eggnog flavor. Eggnog is used in the cookie crust and the frosting, so they are full of holiday cheer.
- Soft and buttery texture. These bars bake up soft and tender, so they taste just like a classic sugar cookie.
- Awesome holiday dessert. Frosted cookie bars are great for cookie trays, Christmas parties, or just because you have leftover eggnog in your fridge.
