Peanut Butter Blossom Bars Ingredients

When I’m developing recipes in my New York kitchen, I always make a trip to my local Union Square Greenmarket for the freshest ingredients, but for pantry staples like these, I rely on my neighborhood supermarket or, honestly, my trusty Amazon grocery delivery! The quality of your peanut butter and chocolate chips can make a big difference, so I always opt for well-known brands. My mother in Morocco used a rich, earthy peanut paste in her sweets, and while different, it inspired me to seek out the creamiest peanut butter for this recipe.

Ingredients List

• 1/2 cup unsalted butter, softened
• 1/2 cup granulated sugar
• 1/2 cup packed light brown sugar
• 1/2 cup creamy peanut butter (use a common commercial brand like Jif or Skippy)
• 1 large egg
• 1 1/2 cups all-purpose flour
• 3/4 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1/8 teaspoon salt
• 2/3 cup milk chocolate chips (or semi-sweet, if you prefer)
• 24 Hershey’s Kisses, unwrapped (milk chocolate is classic)
• 3 teaspoons white sparkling sugar OR granulated sugar, for topping

Ingredient Spotlight

Unsalted Butter: The foundation of our cookie bars, unsalted butter provides richness and helps create that tender texture. Using unsalted allows us to control the salt content precisely. In U.S. supermarkets, you’ll find it in the dairy aisle, typically in 1-pound (4 sticks) or 1/2-pound boxes. Always make sure it’s softened to room temperature for optimal creaming; this means it should yield to gentle pressure but not be melted.

Creamy Peanut Butter: This is the star of the show! For these bars, I recommend using a conventional creamy peanut butter like Jif or Skippy. These have added sugars and oils that contribute to a consistent texture and flavor that bakes up beautifully. Natural peanut butters, which tend to separate and have a looser texture, can sometimes lead to a greasier or less set bar, though they can be used with adjustments (see variations!).

Hershey’s Kisses: The iconic topper that defines this cookie bar. Their smooth milk chocolate melts slightly from the residual heat of the bars, creating a glossy finish while maintaining their shape. While milk chocolate is traditional, you could certainly experiment with dark chocolate or even caramel-filled Kisses for a different flavor profile. Ensure they are unwrapped before baking!

How to Make Peanut Butter Blossom Bars — Step-by-Step

Follow these simple steps, and you’ll have these delightful Peanut Butter Blossom Bars ready in no time!

Step 1: Cream the Wet Ingredients

In a large mixing bowl, combine the softened unsalted butter, granulated sugar, packed light brown sugar, creamy peanut butter, and the large egg. Use an electric mixer on medium speed to beat these ingredients together until the mixture is light, fluffy, and well-combined. This usually takes about 2-3 minutes. Scrape down the sides of the bowl as needed.

💡 mia’s Pro Tip: For the best texture, ensure your butter is truly softened to room temperature – it should give slightly when pressed with your finger but not be greasy or melted. This is crucial for creating that airy base that bakes up tender.

Step 2: Combine Dry Ingredients and Mix Dough

In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Gradually add this dry mixture to the creamed wet ingredients. Stir with a wooden spoon or spatula until just combined and a cohesive dough begins to form. Be careful not to overmix at this stage. Finally, gently stir in the milk chocolate chips.

⚠️ Common Mistake to Avoid: Overmixing the dough after adding the flour. Once flour is incorporated, gluten starts to develop, which can lead to tough, dense bars. Mix only until the flour streaks disappear.

Step 3: Press into Pan and Sprinkle Sugar

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan, or line it with parchment paper, leaving an overhang on the sides for easy lifting later. Press the cookie dough evenly into the bottom of the prepared pan. Once the dough is spread, sprinkle about 2 teaspoons of the white sparkling sugar (or granulated sugar) evenly over the top.

Step 4: Bake the Bars

Bake in the preheated oven for 22-24 minutes, or until the edges are golden brown and the center is puffed up and set. A toothpick inserted into the center should come out with moist crumbs attached, not wet batter. The exact time may vary slightly depending on your oven.

Step 5: Top with Hershey’s Kisses

As soon as you remove the pan from the oven, immediately arrange the unwrapped Hershey’s Kisses over the hot bars. I like to use a pattern of 4 rows by 6 rows to ensure each bar gets a kiss. Sprinkle the remaining teaspoon of white sparkling sugar (or granulated sugar) over the Kisses and the bars.

⚠️ Common Mistake to Avoid: Touching the Hershey’s Kisses after placing them on the hot bars. The residual heat will cause them to melt and glisten beautifully while retaining their shape. If you try to adjust or smooth them, they will smudge and lose their iconic look.

Step 6: Cool and Cut

Let the bars cool completely in the pan on a wire rack. This is crucial! Cooling allows the Kisses to fully set and the bars to firm up. Once completely cool, lift the bars out of the pan using the parchment paper overhang. Cut into squares, ensuring there’s one perfectly shaped Hershey’s Kiss centered in each bar.

Serving & Presentation

These Peanut Butter Blossom Bars are truly a joy to serve, whether at a casual family gathering or a more elegant holiday fête. I love how the glossy Hershey’s Kiss on top adds a touch of whimsy and charm. For a classic presentation, simply cut them into neat squares and arrange them on a pretty platter. The contrast between the warm, chewy peanut butter bar and the cool, smooth chocolate kiss is divine.

In New York, we love our dessert experiences to be both delicious and photogenic! A sprinkle of those sparkling sugar crystals adds a lovely shimmer that catches the light, making them irresistible. You can serve these as is, or alongside a scoop of vanilla bean ice cream if you’re feeling decadent. They are also fantastic dipped for a Parisian touch – perhaps a dark chocolate ganache for those who love a richer profile.

Make-Ahead, Storage & Reheating

In my busy New York life, making ahead is key! These Peanut Butter Blossom Bars are fantastic for preparing a day or two in advance, saving you precious time on busy weeknights or holiday mornings. They store wonderfully, making them perfect for packing in lunches or grabbing for a quick snack. The flavors even meld slightly overnight, which I sometimes think makes them even better!

For optimal freshness, I always store leftovers in an airtight container at room temperature if I plan to eat them within a day or two. If they need to last longer, the refrigerator is the best bet. The Kisses will remain nicely shaped in the fridge, and the bar itself stays delightfully chewy. When reheating, aim for just a few seconds in the microwave; you want to warm the cookie bar slightly without completely melting the Kiss into an unrecognizable puddle.

Variations & Easy Swaps

Chocolate Chunk Peanut Butter Blossom Bars

Instead of milk chocolate chips, I sometimes love to chop up a good quality dark chocolate bar (around 70% cocoa) into rough chunks. This adds larger pockets of intensely flavored chocolate that melt beautifully. This is a simple swap that elevates the chocolate experience without changing the structure of the bar. It’s a little luxury I learned to appreciate during my time in Paris, where bakeries often use high-quality chocolate for their pastries.

Gluten-Free Peanut Butter Blossom Bars

For a gluten-free version, simply swap the all-purpose flour for a good quality 1:1 gluten-free baking blend that contains xanthan gum. I’ve tested this method extensively in my kitchen, and it works wonderfully. The texture remains remarkably similar, maintaining that delightful chewiness. Ensure your gluten-free flour is fresh and well-combined with the other dry ingredients for best results.

Holiday Spice Peanut Butter Blossom Bars

To give these bars a festive, warm hug, especially during the holidays, I like to add about 1/2 teaspoon of ground cinnamon and a pinch of ground nutmeg to the dry ingredients along with the flour. This subtle addition brings a beautiful aroma and a cozy flavor that pairs perfectly with the peanut butter and chocolate, reminiscent of the fragrant spice markets of my childhood in Morocco.
