- Butter (salted or unsalted): Softened butter adds richness and a tender crumb to the cookie base and frosting.
- Granulated sugar: Sweetens the cookie dough and helps create a light texture.
- Brown sugar: Adds moisture and a subtle caramel depth to the bars.
- Egg: Binds the ingredients together and helps with the cookie structure.
- Eggnog: The star ingredient, infusing every bite with creamy holiday flavor.
- Vanilla extract: Enhances the warmth of the flavors and complements the eggnog beautifully.
- All-purpose flour: The foundation for your cookie bars, providing structure and chewiness.
- Baking powder: Helps the bars rise for the perfect soft texture.

- Powdered sugar: Essential for the silky-smooth frosting that tops the bars.
How to Make Eggnog Cookie Bars Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, making sure to leave enough overhang on the sides. This little trick makes lifting your perfectly baked bars out effortless and keeps everything neat when it’s time to slice.
Step 2: Cream Your Butter and Sugars
In a large bowl, cream together the softened butter with both granulated and brown sugars until the mixture becomes light and fluffy. This step takes about 2-3 minutes on medium speed with a mixer. The air you incorporate here is key to those soft, tender bars you’ll love.
Step 3: Combine Wet Ingredients
Next, beat in the egg, eggnog, and vanilla extract. The mixture will come together into a smooth, homogenous batter packed with holiday cheer. The eggnog adds not only moisture but also a magic flavor that makes these bars so special.
Step 4: Mix Dry Ingredients and Combine
In a separate bowl, whisk together the flour, baking powder, nutmeg, and salt. Gradually add this to the wet ingredients, stirring gently until just combined. It’s important not to overmix here to keep the bars tender and not tough.
Step 5: Bake the Bars
Press the cookie dough evenly into the parchment-lined pan, smoothing the top for an even bake. Pop the pan into your preheated oven and bake for 25-27 minutes, or until a toothpick inserted in the center comes out clean. Once baked, allow the bars to cool completely while you prepare the frosting.
Step 6: Whip Up the Frosting
While the bars cool, beat together softened butter, powdered sugar, eggnog, and vanilla extract. The goal is a light, fluffy frosting that’s rich in that festive eggnog flavor, perfect for spreading over the cookie base.
Step 7: Frost and Garnish
Spread the frosting evenly over the cooled cookie bars. For a final festive touch, sprinkle a pinch of nutmeg on top. Chill in the refrigerator briefly to firm up the frosting, then slice into perfect squares and get ready to enjoy.
How to Serve Eggnog Cookie Bars Recipe
Garnishes
Adding a sprinkle of fresh nutmeg or even a dusting of cinnamon can elevate the look and flavor of your bars. Consider some finely chopped toasted pecans or a drizzle of caramel for an extra fancy touch when serving guests.
Side Dishes
These bars pair wonderfully with a hot drink, like a spicy chai latte or a rich cup of coffee. You can also serve them alongside a small scoop of vanilla ice cream or whipped cream for a cozy dessert option.
Creative Ways to Present
Try arranging the bars on a festive platter garnished with fresh cranberries, holly leaves, or even edible gold dust. Wrapping individual bars in parchment with a pretty ribbon makes for charming holiday gifts or party favors.
Make Ahead and Storage
Storing Leftovers
Your leftover Eggnog Cookie Bars Recipe keeps beautifully in an airtight container at room temperature for up to 3 days. For longer storage, refrigeration is a great option and will help the frosting stay fresh and stable.
Freezing
If you want to save some bars for later, you can freeze them for up to 2 months. Wrap them tightly in plastic wrap and foil to protect against freezer burn. Thaw overnight in the fridge before serving to preserve that fresh-from-the-oven taste.
Reheating
For a fresh-baked feel, gently warm your bars in the microwave for about 10-15 seconds. This softens the frosting and reactivates the comforting eggnog aromas, making each bite as delightful as the first.
FAQs
Can I use store-bought eggnog?
Absolutely! Store-bought eggnog works perfectly in the Eggnog Cookie Bars Recipe and helps bring that classic holiday flavor right into your kitchen with ease.
What if I don’t have nutmeg?
If nutmeg isn’t on hand, you can substitute with a pinch of cinnamon or allspice. They offer warm, spicy notes that complement the eggnog nicely.
Are these bars gluten-free?
This recipe calls for all-purpose flour, so it’s not gluten-free as written. However, you could try a gluten-free flour blend in equal measure for a similar texture and flavor.
Can I make the frosting dairy-free?
Yes! Use dairy-free butter and powdered sugar, and substitute the eggnog with a non-dairy alternative for a delicious dairy-free version of these bars.
How long do these bars last?
Stored properly in an airtight container, these Eggnog Cookie Bars Recipe bars stay fresh for about 3-4 days at room temperature or up to a week if refrigerated.
