My peanut butter blossoms are everyone’s classic holiday cookie in bar form! Our kids love that they’re both fun and easy to make! These chewy peanut butter cookie bars are studded with Hershey kisses which make everyone so happy.
My favorite part is that they are easier than cookies; no rolling needed, just slice into bars and serve! Bonus, this recipe includes a how-to video!
Our son was begging for us to make “those Hershey kiss cookies” but I had been running around all day and though it may sound silly, the thought of rolling out every single cookie sounded exhausting; so I made them all in a pan and they turned out adorably delicious!!
Ingredients for Peanut Butter Blossom Cookie Bars
- Peanut Butter: that classic nutty flavor and creamy richness we all love.
- Unsalted Butter: keeps the bars soft and melt-in-your-mouth.
- Sugar and Brown Sugar: sweetness plus a little caramel depth for chewiness.
- Vanilla: ties all the flavors together.
- Egg and Egg Yolk: hold everything together while adding tenderness.
- Flour: gives the bars structure so they bake up just right.
- Baking Soda and Baking Powder: the lift that keeps them light instead of dense.
- Cornstarch: the secret to that soft, chewy bite.
- Salt: just enough to balance the sweetness.
- Hershey’s Kisses: the signature chocolate topper that makes them taste (and look!) like the classic blossom cookies we all grew up with.
How to Make Peanut Butter Blossom Bars
- Prep: Preheat the oven and grease a 9×13 baking dish then line with parchment paper and grease it again.
- Wet Ingredients: Beat together all the wet ingredients in a stand mixer.
- Dry Ingredients: Mix together all the dry ingredients in a separate bowl.
- Combine: Add the dry ingredients to the wet ingredients and mix until combined.
- Bake: Press the dough into the prepared baking dish, sprinkle with sugar and bake for 20-22 minutes.
- Kisses: Unwrap the Hershey’s Kisses and as soon as the bars are done baking, pull them out and top with the kisses.
- Cool: Let the peanut butter bars cool completely and then cut into bars so that a Hershey Kiss is in the center of each bar.
Fun Variation
If you want to try another fun twist, use mini Reese’s Peanut Butter Cups instead of the Hershey’s Kisses. You double down on the peanut butter while still getting the chocolate! My family loves both!
Storage Tips
Leftover peanut butter chocolate dessert bars should be stored in an airtight container. They can be stored at room temperature or in the refrigerator depending on how you like to eat them. They will keep for 4-5 days.
These also freeze extremely well. Let them cool completely so that the Hershey’s Kisses are solid again. Layer in a ziploc bag or freezer safe container separating layers with parchment paper. They will keep in the freezer for up to 3 months.
FAQ
No, I don’t recommend using natural peanut butter. You want the extra sugar and little bit of salt that is in processed peanut butter for these bars.
You will want to add the Kisses after baking. If you add them before, they will completely melt and lose their shape. You’ll add them as soon as you pull the baked bars out of the oven.
No, unfortunately this won’t work. If you need more bars, then double the recipe and split the dough between two 9×13 baking dishes. Bake as written in the recipe card.
I have a few tricks for keeping these cookie bars soft. First, make sure the butter is softened so that you don’t have to overmix to get everything incorporated. Second, don’t skip the cornstarch. It really does wonders for keeping the bars tender. Lastly, Don’t over bake the bars! I start checking them a few minutes early even and as soon as a toothpick comes out of the middle with just a few crumbs, pull them out!
These Peanut Butter Blossom Bars are everything you love about the classic cookie—soft, chewy peanut butter layers topped with melty Hershey’s Kisses—all baked into an easy bar dessert! Perfect for family gatherings, holiday trays, or just because you love peanut butter and chocolate.
