Ingredients & Why They Work

Each ingredient in this Peanut Butter Blondies with Reese’s Pieces Recipe plays a role in creating that irresistible combination of rich flavor and perfect texture. I always recommend using creamy peanut butter for the best moistness, and don’t skip the Reese’s Pieces – they really bring the blondies to life.

• Unsalted Butter: Melting the butter gives a rich, buttery flavor and helps create a chewy texture.
• Brown Sugar: Packed for moisture and that deep caramel-like taste which complements peanut butter perfectly.
• Creamy Peanut Butter: Use processed creamy peanut butter like Jif or Skippy for moist, tender blondies without crumbliness.
• Eggs & Extra Egg Yolk: Eggs bind everything together and the extra yolk adds richness and a chewy bite.
• Vanilla Extract: A little goes a long way in enhancing all the flavors beautifully.
• All-Purpose Flour: Provides structure – spoon and level the flour to avoid dry blondies.
• Baking Powder & Salt: Help with rising just enough and balance out sweetness.
• Reese’s Pieces: The star candy that adds texture, color, and that classic peanut butter-chocolate combo punch.

Make It Your Way

One of my favorite things about Peanut Butter Blondies with Reese’s Pieces Recipe is how versatile it is – you can easily make these your own depending on your mood or what you have on hand. I sometimes swap Reese’s Pieces for peanut butter chips or add a handful of chocolate chunks for extra indulgence.

• Variation: I once swapped plain peanut butter for crunchy and loved the added texture, but for the smoothest bars, creamy is best.
• Dietary Modification: For gluten-free, try almond flour blends and watch the bake time closely.
• Seasonal Twist: Adding mini peanut butter cups during the holidays can turn these blondies into a festive treat.

Step-by-Step: How I Make Peanut Butter Blondies with Reese’s Pieces Recipe

Step 1: Prep Your Pan and Oven

First things first, preheat your oven to 350°F (177°C) and place your rack in the center position. Then, line a 9×13-inch pan with parchment paper, making sure to leave a big overhang on the sides – this trick makes lifting the blondies out super easy and clean. Trust me, it’s worth the little extra step.

Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the melted butter and brown sugar until smooth and glossy. Next, add in your creamy peanut butter and give it a good stir. Then, add the eggs, extra egg yolk, and vanilla extract – whisk everything until it’s completely combined. This step creates the rich and creamy base that makes these blondies so irresistible.

Step 3: Add the Dry Ingredients

Now, add the flour, baking powder, and salt to your wet mixture. Using a rubber spatula, fold everything together gently – the batter will be thick, which is exactly what you want. Finally, fold in the Reese’s Pieces, reserving a few to sprinkle on top for decoration. This way, you’ll get that fun candy crunch throughout and a pretty finish.

Step 4: Bake and Test

Spread the batter evenly in your prepared pan and bake for about 30 minutes. Around 28 minutes, start testing the blondies with a toothpick in the center – you want it to come out with just a few moist crumbs. If it’s still wet, keep checking every couple of minutes. Be careful not to overbake because these blondies taste best when they’re fudgy, not dry.

Step 5: Cool and Slice

Once out of the oven, let your blondies cool completely in the pan resting on a wire rack. The parchment overhang makes it easy to lift them out in one piece. Then cut into squares – I like large pieces for sharing but smaller bites work well too!

How to Serve Peanut Butter Blondies with Reese’s Pieces Recipe

Garnishes

I usually sprinkle a few extra Reese’s Pieces on top right before baking for that little pop of color and fun crunch. Sometimes, I like a light dusting of powdered sugar for an elegant touch, especially if serving at a party. A drizzle of melted chocolate or a smear of peanut butter frosting can totally turn these into a fancy treat, too.

Side Dishes

These blondies are sweet and rich, so I often pair them with a scoop of vanilla ice cream for dessert or a glass of cold milk to balance the richness. For a fun brunch twist, serve them alongside fresh fruit or yogurt to add a fresh note to the indulgence.

Creative Ways to Present

For birthdays or celebrations, I’ve arranged these blondies on a pretty platter with colorful Reese’s Pieces scattered around and little paper flags stuck on toothpicks for a festive look. You can also cut them into bite-sized squares and serve on tiered dessert stands — they disappear fast when presented like that!

Make Ahead and Storage

Storing Leftovers

I keep leftover Peanut Butter Blondies with Reese’s Pieces wrapped tightly in plastic wrap or in an airtight container at room temperature. They hold up really well for about a week — perfect for sneaking a treat during the week without baking again.

Freezing

These blondies freeze beautifully! After baking and cooling completely, I cut them into squares, wrap each piece in plastic, then place them in a freezer-safe container or bag. They keep well for up to three months, and thawing overnight in the fridge works great for soft, fresh-tasting blondies.

Reheating

If you want to enjoy them warm, pop a blondie in the microwave for about 10 seconds — just enough to soften the peanut butter and release those wonderful aromas without drying it out. They’re a little slice of heaven when warm, especially paired with a scoop of ice cream.
