My kids especially enjoy pushing the extra Reese's cups onto the top. Seeing their joy as the squares bake has turned into one of our cherished baking moments together.

Perfect Baking Technique

Getting that amazing texture depends on the right oven heat and cooking time. Watch for golden edges with a slightly soft middle part.

Smart Ingredient Choices

Going with standard smooth peanut butter instead of the natural kind makes sure your bars set up right and have the best feel.

Smart Tray Setup

Using parchment paper in your tray makes getting the bars out and cutting them so much easier.

Keeping Them Fresh

They'll stay tasty in a sealed container for about three days on your counter. Put them in the fridge for up to a week. Wrap pieces separately and freeze them for up to two months.

After making these squares tons of times, I've learned that waiting patiently while they cool is crucial for the best texture. This chocolate and peanut butter mix creates such a tempting treat that they're always the first to vanish at any party.

Frequently Asked Questions

→ Can I choose different Reese’s types?
Absolutely, any style works! Chop up bigger ones if needed. Mix white chocolate Reese’s with regular for something new.
→ Why is cooling so important?
It helps the bars firm up so you can cut them nicely. If they’re warm, they might break apart and be too soft.
→ Can mix-ins be switched up?
Sure thing! Add in shredded coconut, nuts, or different chips. Just stick to about 2.5 cups total to avoid overloading.
→ Is freezing an option?
Yep! Slice into squares first, wrap them tight, and freeze for up to 3 months. Let them thaw before eating.
→ Do I really need parchment paper?
It’s super helpful! Makes pulling the batch out for slicing smooth and mess-free, no extra grease required.

Ingredients

→ Wet Ingredients

01 1 cup peanut butter, smooth and creamy
02 2 teaspoons vanilla, pure extract
03 2 eggs, large-sized
04 1 cup (2 sticks) salted butter, melted and cooled to room temperature

→ Dry Ingredients

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

→ Mix-Ins

10 1/2 cup mini chocolate chips (set aside 2 tablespoons for later)
11 2 cups Reese's mini peanut butter cups, halved (reserve 1/2 cup for the top)

Instructions

Step 01

Set your oven to 350°F. Grab a 9x13 pan and line it with parchment, leaving the edges to hang over for easy removal. No parchment? Spray it really well with non-stick spray.

Step 02

Use an electric hand mixer or a stand mixer with a paddle. In a big mixing bowl, blend the melted butter, peanut butter, eggs, vanilla, white sugar, and brown sugar until it's creamy and smooth.

Step 03

Toss in the flour, salt, and baking soda. Use low speed to stir until you can't see any dry flour bits. Stop mixing as soon as it's combined—don't overdo it!

Step 04

Fold in most of the Reese's chunks and chocolate chips. Save a little of each to sprinkle on top later. Mix just enough so they're spread out evenly.

Step 05

Push the dough into your pan so it spreads evenly. Use your hands or a spatula to smooth the surface. Top with the left-over Reese's and chocolate chips, pressing them lightly into the dough.

Step 06

Bake for 25 to 30 minutes. When the edges are golden and a toothpick poked in the middle comes out mostly clean (some gooey crumbs are fine), take it out. Let it cool fully before cutting it up.

Notes

  1. Need melted butter? Heat it for about 45 seconds in the microwave until half liquid, half soft, then stir till smooth.
  2. Only have unsalted butter? Add 1/2 teaspoon salt instead of 1/4 teaspoon.
  3. Want to try something different? Swap in other Reese's varieties! Just chop them into smaller pieces first.
