Recipe Card


Ingredients
- 2 cups flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1 teaspoon kosher salt
- 2 sticks unsalted butter , softened
- ½ cup peanut butter
- 1 cup dark brown sugar , firmly packed
- 1 cup sugar
- 2 large eggs
- 1 tablespoon vanilla
- 3 cups rolled oats
- 40 Reese’s Pieces Candies
Instructions
- Preheat oven to 350 degrees.
- In a medium bowl whisk together the flour, baking soda, baking powder, and kosher salt.
- In your stand mixer cream the butter and sugar for 1-2 minutes on high until light and fluffy.
- Add in the dark brown sugar, peanut butter, eggs and vanilla and mix until fully combined.
- Add in the dry ingredients a third of it at a time until just incorporated.
- Add in the oats, and candies and mix in on low for just a few seconds until combined.
- Refrigerate your dough for 30 minutes AT LEAST (the longer the better).
- Depending on the size of the cookies you want, your baking time will vary.
- For large cookies as pictured, using an ice cream scoop (¼ cup) drop onto greased pan or using a silpat liner, bake for 12-14 minutes (I get 18 cookies).
- For medium cookies, using a two tablespoon measure (like a coffee scoop, the one I use is double duty with a 2 tbsp measure on one side and a 1 tbsp measure on the other side) bake for 11-13 minutes (I get 36 cookies).
- For small cookies, using a 1 tablespoon measure, bake for 9-11 minutes (I get 72 cookies).
- You don’t need the cookies to brown too much, so the moment the bottoms get brown, pull them out.

Sabrina’s Tips
These cookies are not only delicious but are pretty low maintenance. I almost always refrigerate my dough before baking. It helps tremendously to have the butter in your recipe harden back up. Warm butter will lead to cookie pancakes. Also, you can freeze this dough for baking later, if you do freeze the dough, scoop them into balls before freezing and be sure to either defrost dough in the fridge or add 1-2 minutes to your cooking time. This will make for a more beautiful cookie every time!
