How to Make Peanut Butter No Bake Cookies with Reese’s Pieces Recipe
Step 1: Create the Sugar Base
Start by combining the sugar, milk, and butter in a large pot over medium-high heat. Bring this mixture to a rolling boil, then let it boil for exactly one minute. This step is crucial because it dissolves the sugar and creates that perfect syrupy base that holds your cookies together.
Step 2: Add Flavor and Creaminess
Remove the pot from heat and immediately stir in the vanilla extract, a pinch of salt, and the creamy peanut butter. Mixing these in while everything is hot allows the peanut butter to melt seamlessly, giving the mixture that silky smooth texture and rich taste.
Step 3: Fold in Oatmeal and Reese’s Pieces
Now, gently fold the quick cook oatmeal into the pot until everything is evenly coated. Then, carefully mix in the Reese’s Pieces candy. Be gentle here so the candies retain their shape and color, creating those beautiful pops throughout your cookies.
Step 4: Form the Cookies
Using a spoon, drop generous spoonfuls of the cookie dough onto parchment paper laid out on your counter or baking sheet. The mixture will be warm and sticky, but it’s fun to shape these little mounds that are bursting with peanut buttery goodness and colorful candy.
Step 5: Let Them Set
Allow the cookies to cool and set at room temperature for about 20 minutes. This resting time lets them firm up just enough to hold their shape while staying perfectly chewy and soft inside.
Step 6: Store and Enjoy
Once set, transfer your Peanut Butter No Bake Cookies with Reese’s Pieces Recipe treats to an airtight container to keep them fresh and ready for snacking any time of day.
How to Serve Peanut Butter No Bake Cookies with Reese’s Pieces Recipe
Garnishes
While these cookies are amazing on their own, a light dusting of powdered sugar or a drizzle of melted chocolate can add an extra touch of elegance and sweetness. You could also press a few extra Reese’s Pieces on top before setting if you want a candy explosion right from the first bite.
Side Dishes
Pair these cookies with a cold glass of milk or a creamy cup of hot cocoa for a comforting snack time. They also complement vanilla ice cream beautifully if you want to create a simple ice cream sandwich for a summery indulgence.
Creative Ways to Present
Looking to impress guests? Arrange the cookies on a colorful platter alongside assorted nuts and fresh fruit to balance the sweetness. You can even stack them with small layers of parchment paper and tie with a rustic ribbon for a charming homemade gift.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cookies in an airtight container at room temperature for up to one week. Their delightful chewy texture stays fresh, making them a perfect make-ahead sweet snack for busy days.
Freezing
If you want to save these treats for longer, freeze them in a single layer on a baking sheet first, then transfer to a freezer-safe container or bag. They freeze beautifully for up to three months without losing any flavor or texture.
Reheating
When ready to enjoy frozen cookies, simply thaw them at room temperature for 15 to 20 minutes. If you like them slightly warm, pop them in the microwave for 10 seconds—just enough to soften the peanut butter center while keeping the candy intact.
FAQs
Can I substitute crunchy peanut butter for creamy in the Peanut Butter No Bake Cookies with Reese’s Pieces Recipe?
Absolutely! Crunchy peanut butter will add a delightful nutty texture that complements the oatmeal well, but be aware it may change the cookie’s consistency slightly by introducing some crunch.
Do I have to use quick cook oatmeal?
Quick cook oatmeal works best because it absorbs moisture efficiently and ensures the cookies set properly. Using old-fashioned oats could make the cookies a bit tougher and less cohesive.
Can I use other candies instead of Reese’s Pieces?
Yes, feel free to experiment with M&Ms, chocolate chips, or even chopped nuts. However, Reese’s Pieces provide a unique flavor and color combo that pairs wonderfully with peanut butter.
How long do these cookies last?
Stored properly at room temperature, these cookies stay fresh and delicious for about a week, making them great for prepping ahead of time.
Are these cookies gluten-free?
That depends on the oatmeal you use—make sure to pick certified gluten-free oats to keep this recipe gluten-free and safe for those with sensitivities.
