My children particularly love helping press the extra Reese's cups on top. Watching their excitement as the bars bake has become one of our favorite baking traditions.

Temperature Mastery

The key to perfect texture lies in proper oven temperature and timing. Look for golden edges and slightly soft center.

Ingredient Selection

Using regular creamy peanut butter rather than natural varieties ensures proper texture and setting.

Pan Preparation

Lining the pan with parchment paper makes removal and cutting much easier.

Storage Success

Keep fresh in airtight container up to three days at room temperature. Store in refrigerator up to week. Freeze individually wrapped pieces up to two months.

After countless batches of these bars, I've found that patience during cooling is key to perfect texture. The combination of chocolate and peanut butter creates an irresistible treat that disappears quickly at any gathering.

Frequently Asked Questions

→ Can I use different kinds of Reese's cups?
Yes! Any variety works great - just chop larger ones into smaller pieces. Try mixing white chocolate Reese's with regular for variety.
→ Why let them cool completely?
The bars need to set fully for clean cuts and best texture. If cut while warm, they'll be too soft and might fall apart.
→ Can I add other mix-ins?
Sure! Try nuts, different chips, or coconut. Just keep the total amount of mix-ins to about 2.5 cups so the dough holds together.
→ Can I freeze these bars?
Yes! Cut into squares, wrap well, and freeze for up to 3 months. Thaw at room temperature when ready to enjoy.
→ Why use parchment paper?
Parchment helps lift the whole batch out easily for cutting. Plus, it prevents sticking without extra grease.

Yield: 18 Servings

Ingredients

→ Wet Ingredients

01 1 cup (2 sticks) salted butter, melted and slightly cooled
02 1 cup creamy peanut butter
03 2 large eggs
04 2 teaspoons vanilla extract

→ Dry Ingredients

05 1 cup granulated sugar
06 1 cup light brown sugar, packed
07 2½ cups all-purpose flour
08 1 teaspoon baking soda
09 1/4 teaspoon kosher or sea salt

→ Mix-Ins

10 2 cups miniature Reese's peanut butter cups, halved (save 1/2 cup for topping)
11 1/2 cup mini semi-sweet chocolate chips (save 2 tablespoons for topping)

Instructions

Step 01

Heat your oven to 350°F. Line a 9x13 baking pan with parchment paper, leaving some hanging over the sides for easy lifting later. If you don't have parchment, spray the pan well with cooking spray.

Step 02

In a large bowl with an electric mixer (or stand mixer with paddle), beat together the melted butter, both sugars, peanut butter, eggs, and vanilla until everything's well combined and smooth.

Step 03

Add flour, baking soda, and salt to your bowl. Mix on low speed just until combined and no dry flour spots remain. Don't overmix!

Step 04

Gently stir in most of the halved Reese's cups and chocolate chips (remember to save some for the top). Mix just until they're evenly spread through the dough.

Step 05

Spread the dough evenly in your prepared pan. Smooth the top with a spatula or clean hands. Sprinkle those reserved Reese's pieces and chocolate chips over the top, pressing them in slightly.

Step 06

Bake for 25-30 minutes until the edges are golden brown and a toothpick in the center comes out with just a few moist crumbs. Let cool completely in the pan before cutting into squares.

Notes

  1. To melt butter perfectly, microwave for 45-50 seconds - you want half melted, half soft, then stir until completely smooth
  2. Using unsalted butter? Increase salt to 1/2 teaspoon
  3. Feel free to swap in different Reese's varieties - just chop them small first
