• ½ teaspoon ground cinnamon – Adds cozy warmth.
• ½ teaspoon salt – Balances the sweetness.
• ¾ cup white chocolate chips – Melt into pockets of creamy sweetness throughout the bars.

For the Eggnog Glaze

• 1½ cups powdered sugar – Creates a smooth, sweet glaze.
• 3 tablespoons eggnog – Gives the glaze its creamy consistency and festive flavor.
• ½ teaspoon vanilla extract – Adds depth and aroma.
• ⅛ teaspoon ground nutmeg – Reinforces the classic eggnog flavor.

Step-by-Step Instructions

Step 1: Prepare the Baking Pan

Preheat your oven to 350°F (175°C).

Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.

Lightly grease any exposed sides of the pan.

Step 2: Mix the Wet Ingredients

In a large mixing bowl, whisk together:

• Melted butter
• Brown sugar
• Granulated sugar

Whisk until the mixture becomes smooth and glossy.

Add:

• Egg
• Egg yolk
• Eggnog
• Vanilla extract

Continue whisking until fully combined and creamy.

Step 3: Add the Dry Ingredients

Add the flour, ground nutmeg, cinnamon, and salt.

Using a spatula or wooden spoon, gently mix until no dry streaks remain.

Avoid overmixing to keep the bars soft and tender.

Step 4: Fold in the White Chocolate

Fold the white chocolate chips evenly throughout the batter.

Spread the batter into the prepared baking pan and smooth the top with a spatula.

Step 5: Bake

Bake for 28–32 minutes, or until:

• The edges are lightly golden.
• The center appears just set.
• A toothpick inserted into the center comes out with a few moist crumbs.

Do not overbake, as the bars will continue setting while cooling.

Step 6: Cool Completely

Allow the bars to cool completely in the baking pan before adding the glaze.

Cooling prevents the glaze from melting and running off the bars.

Step 7: Make the Eggnog Glaze

In a medium bowl, whisk together:

• Powdered sugar
• Eggnog
• Vanilla extract
• Nutmeg
• Pinch of salt

Whisk until smooth.

If necessary, add a tiny splash of additional eggnog until the glaze reaches a spreadable consistency.

Step 8: Glaze the Bars

Spread the glaze evenly over the cooled bars using an offset spatula or the back of a spoon.

Allow the glaze to set for 20–30 minutes before slicing.

Step 9: Slice and Serve

Lift the bars from the pan using the parchment paper.

Slice into 16 squares using a sharp knife.

For the cleanest cuts, wipe the knife clean between each slice.

Recipe Notes & Tips

• Don’t Overbake – Slightly underbaked centers create the fudgy texture that makes these bars irresistible.
• Cool Completely Before Glazing – Warm bars can cause the glaze to melt and become too thin.
• Use Room Temperature Eggnog – It blends more smoothly into both the batter and glaze.
• Measure Flour Correctly – Spoon flour into the measuring cup and level it off to avoid dense bars.
• Chill Before Cutting – Refrigerating the glazed bars for 20–30 minutes makes slicing much cleaner.
• Fresh Nutmeg Adds Incredible Flavor – If available, grate whole nutmeg for the most aromatic result.

• Freeze for Later – Freeze individual bars for up to 3 months. Thaw overnight in the refrigerator before serving.
• Serve Slightly Chilled or at Room Temperature – Both bring out the creamy texture and warm spice flavors.

Creative Variations to Try

Troubleshooting Common Issues

• Bars Are Dry – They were likely overbaked. Remove them as soon as the center is just set.
• Glaze Is Too Thin – Add more powdered sugar until it reaches a thicker consistency.
• Glaze Is Too Thick – Whisk in a teaspoon of eggnog at a time until smooth.
• Bars Crumble When Sliced – Chill the bars before cutting and use a clean, sharp knife for each slice.
