Ingredient List
- 1 cup unsalted butter, melted
- 1 cup peanut butter, I use Jif, Skippy, or similar; avoid natural PB that can separate and/or be too oily
- 1 large egg
- 1 cup light brown sugar, packed
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- About 9 unwrapped chocolate Kisses, if you cut your bars smaller, you’ll need more Kisses
Tools & Equipment Needed
- Mixing Bowl: For combining your ingredients.
- Whisk or Electric Mixer: To ensure a smooth batter.
- Baking Pan: A 9×9 inch pan works best for these bars.
- Parchment Paper: For easy removal of the bars from the pan.
- Spatula: For spreading the batter evenly in the pan.
Peanut Butter Blossom Cookie Bars: From Prep to Plate

Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your Peanut Butter Blossom Cookie Bars bake evenly.
Step 2: Prepare Your Baking Pan
Line a 9×9 inch baking pan with parchment paper. This will help you lift the bars out easily once they are baked and cooled.
Step 3: Mix Wet Ingredients
In a large mixing bowl, combine the melted unsalted butter and peanut butter. Whisk them together until the mixture is smooth and creamy. Then, add in the egg, light brown sugar, and vanilla extract. Mix until everything is well incorporated.
Step 4: Add Dry Ingredients
Gently fold in the all-purpose flour until just combined. Be careful not to overmix; you want the batter to remain light and airy.
Step 5: Bake the Bars
Pour the batter into your prepared baking pan and spread it evenly using a spatula. Bake in the preheated oven for 20-25 minutes or until the edges are golden brown and the center is set.
Step 6: Add the Chocolate Kisses
Once the bars are out of the oven, let them cool for about 5 minutes before placing the unwrapped chocolate Kisses on top. Gently press each Kiss into the warm bars, allowing them to melt slightly.
Step 7: Cool and Cut
Let the bars cool completely in the pan on a wire rack. Once cool, lift them out using the parchment paper and cut into squares or rectangles. Enjoy your delicious Peanut Butter Blossom Cookie Bars!
Make It Year-Round

- Seasonal Twists: Add in seasonal ingredients like crushed peppermint for the winter holidays or sprinkles for birthday celebrations.
- Nut Variations: Substitute peanut butter with almond or cashew butter for a different flavor profile.
- Chocolate Options: Use different types of chocolate candies or even drizzles to customize your bars.
- Healthier Alternatives: Experiment with whole wheat flour or natural sweeteners for a healthier version.
