Hello, fellow food enthusiasts!
In these unpredictable times, it’s easy to lose track of days, weeks, or even seasons. While this recipe might be a bit past Valentine’s Day, I believe some treats are timeless.

Losing track of time has definitely been a theme lately. As someone who usually works from home, I’m quite comfortable in my space. However, my daily gym ritual was my cherished outing, my mental reset button. With that temporarily on hold (and completely understandable, as we prioritize health and safety in places like Las Vegas to beat this virus), I’ve found myself channeling my energy into the kitchen. Baking and cooking have become my anchors, my creative outlet.
I strive to make at least one fresh, delicious meal a day, and baking sessions happen whenever inspiration strikes. I’m trying to be mindful of my pantry staples to avoid too many grocery trips, but let’s just say my egg supply is diminishing rapidly! It’s a small challenge that makes each baked good feel even more precious.

Why These Reese’s Peanut Butter Blondies Are an Absolute Must-Try
These Peanut Butter Blondies aren’t just a dessert; they’re an experience, especially for dedicated peanut butter lovers! What makes them so special? It’s their perfect balance of rich, moist texture and intense peanut butter flavor, elevated by the delightful surprise of Reese’s candy. They come together incredibly fast, making them the ideal sweet treat when you’re short on time but big on cravings. The simplicity of the recipe belies the complex satisfaction each bite delivers.
But the true magic of these blondies lies in their incredible versatility. The base recipe is a blank canvas, ready to be customized to suit your mood and whatever ingredients you have on hand. Here are some fantastic variations I frequently enjoy:
- Classic Peanut Butter Blondies – When I’m feeling effortlessly chic or simply yearning for that pure, unadulterated peanut butter goodness, I sometimes skip the Reese’s candies. The blondie itself boasts such a deep, satisfying flavor that it truly shines on its own.
- Peanut Butter Blondies with Mini Chocolate Chips – Is there a more iconic duo than peanut butter and chocolate? I think not! You can fold a generous handful of mini chocolate chips directly into the blondie batter for a hidden burst of chocolate, or sprinkle them on top before baking for a visual and textural delight.
- Peanut Butter Blondies with Cheesecake Swirls – As a huge cheesecake fan, incorporating it into blondies and brownies is one of my favorite indulgences! Imagine ribbons of tangy, creamy cheesecake swirling through the sweet, nutty blondie. It adds an irresistible layer of richness and complexity that takes these blondies to an entirely new level.
- Crunchy Peanut Butter Blondies with Added Nuts – For those who adore texture, either opt for crunchy peanut butter in the recipe or, even better, stir in some chopped roasted peanuts or pecans into the batter. This creates a glorious double dose of peanut deliciousness and a satisfying crunch with every bite.
- Peanut Butter Blondies with Nutella Swirls – Prepare for a true chocolate and peanut butter explosion! Swirling creamy Nutella into the top of the blondie batter before baking not only creates a stunning marble effect but also infuses the blondies with a heavenly hazelnut chocolate flavor. These beautiful and incredibly decadent blondies are the perfect pick-me-up for any day, especially when you need a special treat.
With all these mouth-watering peanut butter variations, what are you waiting for? Dive into the world of homemade blondies and discover your new favorite dessert!

Essential Ingredients for Perfect Peanut Butter Blondies
To create these unforgettable Reese’s Peanut Butter Blondies, gather these simple yet powerful ingredients. Each plays a crucial role in achieving that perfect chewy texture and rich flavor:
- Unsalted Butter: Melted butter contributes to the dense, chewy texture of blondies, unlike softened butter in cookies which can create a lighter crumb. Using unsalted butter gives you control over the overall saltiness.
- Light Brown Sugar: Packed brown sugar is key for moisture and chewiness, thanks to its molasses content. It also adds a lovely caramel note that complements the peanut butter beautifully.
- Large Egg: One room temperature egg acts as a binder, providing structure and richness. Room temperature eggs emulsify better with other ingredients, leading to a smoother batter.
- Pure Vanilla Extract: A teaspoon of good quality vanilla extract enhances all the other flavors, adding depth and warmth to the blondies.
- Creamy Peanut Butter: This is the star ingredient! Use a classic creamy peanut butter (like Jif or Skippy) for the best texture and flavor consistency in your blondies. Natural peanut butter can sometimes separate and affect the final texture.
- Fine Sea Salt: Salt is essential for balancing the sweetness and intensifying the peanut butter flavor. Don’t skip it!
- All-Purpose Flour: Standard all-purpose flour provides the necessary structure without making the blondies tough, as long as you avoid overmixing.
- Reese’s Peanut Butter Hearts, Cups, or Minis: While the heart shape adds a festive touch, any form of Reese’s peanut butter candy will work perfectly. They add an extra layer of chocolatey, peanut buttery goodness.

No Heart-Shaped Reese’s? No Problem! Creative Substitutions
Don’t fret if those adorable heart-shaped Reese’s candies aren’t available! While they add a charming touch, they are certainly not mandatory for the success of this recipe. You can effortlessly substitute them with classic Reese’s Peanut Butter Cups, Reese’s Minis, or even chopped up Reese’s bars. The goal is to infuse that iconic chocolate and peanut butter flavor, regardless of the shape.
If Reese’s isn’t your preference, or if you simply want a pure peanut butter experience, these blondies are absolutely fantastic on their own. Their inherent peanut butter flavor is so rich and satisfying that, in my humble opinion, they truly don’t need anything else. They are a testament to the power of a well-crafted blondie base.
However, if you’re set on getting those festive heart shapes, I was indeed able to find them on Amazon. Just remember to check for seasonal availability!

How to Bake the Best Peanut Butter Blondies
Creating these delightful blondies is a straightforward and rewarding process. Follow these easy-to-understand steps, complete with visual cues, to achieve perfectly chewy and flavorful peanut butter blondies every time. For a more detailed recipe card, simply scroll down to the bottom of this page!
Below you will find easy simplified steps for this peanut butter blondie recipe. You can scroll down for the detailed version 🙂
- First, preheat your oven to 350°F (175°C). Prepare an 8×8 inch baking pan by lining it with parchment paper, leaving an overhang on the sides for easy removal. Set this aside.
- In a medium-sized, microwave-safe bowl (or a saucepan on the stove), melt the butter. Once melted, add the light brown sugar and whisk vigorously until the sugar is fully incorporated and the mixture is smooth and glossy.
- Next, add the room temperature egg and vanilla extract to the butter-sugar mixture. Whisk again until everything is well combined and homogenous. Then, stir in the creamy peanut butter until the mixture is smooth and luxurious.
- Gently fold in the all-purpose flour and salt. Mix just until no streaks of flour remain. It’s crucial not to over-mix at this stage, as overworking the gluten can lead to tough blondies.
- Pour the prepared peanut butter blondie batter into your lined baking dish, spreading it evenly with a spatula. Bake for approximately 20 minutes, or until the edges are set and lightly golden, and a toothpick inserted into the center comes out with moist crumbs, not wet batter.
- Once the blondies are baked, remove them from the oven and let them cool in the pan for about 10 minutes. While they are cooling, unwrap your chosen Reese’s candies.
- After the initial cooling period, carefully arrange and press the 16 Reese’s candies (or your chosen substitute) evenly over the top of the warm blondies. This allows the candies to slightly melt and adhere. Allow the blondies to cool further before slicing and enjoying! For cleaner slices, you can let them cool completely and even chill them briefly before cutting.

Pro Tips for Baking the Best Homemade Peanut Butter Blondies!
Achieving bakery-quality peanut butter blondies at home is easier than you think, especially with these insider tips:
- Avoid Overmixing the Batter: This is arguably the most crucial tip for any bar cookie! Once you’ve added the flour to your peanut butter blondie batter, mix it *just* until the dry ingredients are combined and no streaks of flour are visible. Overmixing develops the gluten in the flour, which can lead to a tough, cakey blondie rather than the desired chewy and soft texture we’re aiming for. A gentle hand is key here.
- Patience is a Virtue When Adding Reese’s Candies: I speak from experience! When I first made these, my excitement got the better of me, and I pressed the Reese’s hearts onto the blondies right out of the oven. As you might notice in some of the photos below, they didn’t quite retain their perfect heart shape. To ensure your Reese’s candies keep their distinct form and don’t melt too much, allow the blondies to cool down for at least 5-10 minutes (or even a bit longer) before gently pressing the candies onto the surface. This slight cooling period will make all the difference in presentation.
- Don’t Overbake: Blondies are meant to be slightly underbaked in the center for that perfect chewy, gooey consistency. The edges should be set and lightly golden, but the center might still look a little soft. They will continue to set as they cool.
- Use Room Temperature Ingredients: Ensure your egg is at room temperature. This helps it emulsify better with the melted butter and sugar, creating a smoother, more uniform batter and a more consistent final product.
- Proper Storage: Store any leftover blondies in an airtight container at room temperature for up to 3-4 days to maintain their freshness and chewiness. For longer storage, you can freeze individual blondies (without Reese’s on top if you want them to stay perfectly shaped, otherwise it’s fine) wrapped tightly in plastic wrap and then placed in a freezer-safe bag for up to 2-3 months. Thaw at room temperature before enjoying.
- Achieve Clean Slices: For beautifully neat squares, allow the blondies to cool completely, preferably chilling them in the refrigerator for at least 30 minutes to an hour. Use a sharp knife, wiping it clean between each cut, to prevent sticking and achieve those clean, Instagram-worthy slices.
