🍪 Reese’s Pieces Chocolate Chip Cookie Bars Recipe
🕒 Prep Time: 15 minutes
🍽️ Cook Time: 25–30 minutes
🍫 Yield: About 24 bars (depending on size)
✅ Ingredients:
Dry Ingredients:
-
2 ¼ cups (280g) all-purpose flour
-
1 tsp baking soda
-
½ tsp salt
Wet Ingredients:
-
1 cup (2 sticks / 226g) unsalted butter, softened
-
¾ cup (150g) granulated sugar
-
¾ cup (150g) light brown sugar, packed
-
2 large eggs
-
2 tsp pure vanilla extract
Mix-ins:
-
1 ½ cups semi-sweet chocolate chips
-
1 cup Reese’s Pieces candies (plus a few extra for topping)
-
Optional: ½ cup chopped Reese’s peanut butter cups for more peanut butter flavor
👩🍳 Instructions:
1. Prep the oven and pan:
-
Preheat your oven to 350°F (175°C).
-
Line a 9×13-inch baking dish with parchment paper or grease it lightly with butter or nonstick spray.
2. Mix dry ingredients:
-
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
3. Cream the butter and sugars:
-
In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy (about 2–3 minutes) using a hand mixer or stand mixer.
4. Add eggs and vanilla:
-
Beat in the eggs, one at a time, scraping down the bowl between additions.
-
Add the vanilla extract and mix until combined.
5. Add dry to wet:
-
Gradually add the dry ingredients to the wet mixture. Mix just until combined — do not overmix.
6. Fold in the mix-ins:
-
Stir in the chocolate chips and Reese’s Pieces (and peanut butter cups if using) with a spatula or wooden spoon.
7. Transfer to pan:
-
Press the cookie dough evenly into your prepared 9×13-inch pan.
-
Sprinkle a few extra Reese’s Pieces and chocolate chips on top for presentation.
8. Bake:
-
Bake for 25–30 minutes, or until the top is golden brown and a toothpick inserted near the center comes out mostly clean (a few moist crumbs are okay).
-
If the edges begin to brown too quickly, tent the pan loosely with foil.
9. Cool and cut:
-
Allow to cool in the pan for at least 30 minutes.
-
Lift out using the parchment paper (if used) and cut into squares or bars.
🍫 Optional Add-Ins & Variations:
-
Swap chocolate chips for milk chocolate or white chocolate chips.
-
Add a peanut butter swirl: warm ¼ cup of peanut butter and drizzle it on top before baking. Swirl with a knife.
-
Use mini Reese’s Pieces for better distribution.
📦 Storage:
-
Store in an airtight container at room temperature for up to 5 days.
-
For longer storage, freeze bars for up to 2 months. Wrap individually in plastic wrap, then place in a freezer bag.
