Ingredients

• 1 cup creamy peanut butter

• 1 cup granulated sugar

• 2 large eggs

• 24 chocolate kisses (or chocolate chips)

Optional add-ins: 1 teaspoon vanilla extract, a pinch of salt, and a sprinkle of flaky sea salt for the tops.

Directions

1. Preheat oven to 350°F and lightly grease an 8×8-inch or 9×9-inch baking dish.

2. In a large bowl, stir together the peanut butter, sugar, eggs (and vanilla and salt, if using) until smooth and evenly combined.

3. Spread the dough evenly into the prepared baking dish, smoothing the top with a spoon or spatula.

4. Bake for 20 to 25 minutes, or until the edges are golden and the center is just set.

5. Remove from the oven and immediately press a chocolate kiss into each square, spacing them evenly. Let cool completely before cutting into bars.

Serving Ideas

These bars are lovely served with a glass of cold milk or a cup of coffee, and they make a beautiful addition to a holiday cookie tray. For a cozy dessert plate, pair them with sliced apples or a small scoop of vanilla ice cream, or wrap them individually as homemade gifts.

Variations & Tips

• Peanut Butter Tip: Use creamy peanut butter rather than natural or crunchy so the bars hold together nicely.

• Cookie Tip: Don’t overbake—pull the bars when the center is just set so they stay chewy.

• Add-Ins: A handful of chocolate chips or chopped peanuts folded into the dough adds extra texture.

• Storage: Store in an airtight container at room temperature up to 1 week, or freeze baked bars up to 3 months.
