It’s not your birthday, there’s no celebration or special event.

But you still feel it, sometimes I do too.

The desire for a little extra, a delightful treat just because.

Maybe a batch of Toaster Oven Baked Potato Wedges or a perked-up avocado toast with roasted bits of cauliflower and jalapeno? Even better, sinfully delicious dark chocolate peanut butter cups in a small batch of peanut butter cookies!

This whole grain cookie recipe is simple, made in just one bowl, and calls for creamy natural peanut butter (you know, the kind where the peanut butter and oil separate) but you can use any kind you want.

Irresistible Peanut Butter Cup Cookies (Made w/Natural PB)

Ingredients

  • 2 tablespoons unsalted butter, softened
  • 3 tablespoons natural creamy peanut butter
  • 1/4 cup and 1 tablespoon packed organic brown sugar*
  • 1/8 teaspoon pure vanilla extract
  • 1 large egg white
  • 1/3 cup white whole wheat flour, (or sub All-Purpose flour)
  • 1/8 teaspoon baking soda
  • 1/8 teaspoon baking powder
  • 1/8 teaspoon fine sea salt, (plus more for sprinkling)
  • 3 mini dark chocolate peanut butter cups, roughly chopped

Instructions

  1. In a medium bowl, use a hand mixer to cream the butter, peanut butter and sugar until light and fluffy (about 2 mins). Beat in vanilla and egg white. Set mixer to a low speed and beat in flour, baking soda, baking powder and salt.
  2. Stir chopped peanut butter cups into dough and refrigerate for 30 minutes.
  3. While dough chills, preheat your toaster oven to 375℉ and lightly grease your cookie sheet or line with a toaster oven silicone baking mat.
  4. Roll dough into 8 balls and place on prepared cookie sheet at least 1-inch apart (cookies will spread while baking). Sprinkle dough with salt if using.
  5. Bake for 11 to 13 minutes until the cookies are set and edges are lightly golden.
  6. Cool cookies on sheet for 5 minutes before transferring to a baking rack to cool completely.

Notes

Convection Toaster Oven: Reduce temperature to 350℉ and bake for 8 to 11 minutes.

Prep Time includes 30 minutes inactive time chilling dough.

You can substitute traditional dark brown sugar for the organic. Light brown sugar works too but results in a milder flavor. Dough made with traditional brown sugar will spread more, only bake 4 cookies at a time.

3 Tips For Baking Cookies With Natural Peanut Butter

  • Use a Half-Filled Jar: A fresh jar always has loads of oil at the top, an almost empty jar can be stiff and dry.  We usually hit the perfect oil: peanut ratio halfway through a jar.
  • Chill Your Dough: Ugh, I hate chilling cookie dough too but natural PB can cause your cookies to spread. A visit to the fridge helps you bake 8 separate cookies and not a giant cookie puddle.
  • Be Forgiving: Cookies made with natural peanut butter are like snowflakes, no two batches will be identical.  Equally delicious but always slightly different.

“You got chocolate in my peanut butter!”

How do you make a subtly sweet peanut butter cookie that’s crispy on the outside, soft and chewy on the inside even better? Stir in rich and decadent dark chocolate.

We use the mini PB cups from Trader Joe’s. They’re filled with melty peanut butter and you can get a small bag for just $1.00. Frugal + Delicious, does it get better?

If you don’t have mini PB cups no worries, chop up a large peanut butter cup or substitute 2-3 tablespoons of mini chocolate chips.

Either way you can treat yourself to a special peanut butter chocolate treat.

For no reason really, just because.
