Crunchy peanut butter cookies are filled with a sweet, creamy peanut butter filling to make the most delicious homemade peanut butter cookies sandwiches you've ever had!

Crunch peanut butter cookies with easy peanut butter filling are fun to bake with kids.

You might be from Minnesota if:

  • It's "a hotdish," not a casserole.
  • The "salad" on your Thanksgiving table has Snickers bars mixed in.
  • You've been accused of being "Minnesota Nice" but it only makes you smile bigger.

As a Wisconsin girl married to a Minnesota boy, there's been a fair amount of rivalry in our marriage over the last 18 years. He knows how to push my buttons and I may be guilty of threatening to not serve dinner if he calls it a hotdish one more time.

But when I saw "The Great Minnesota Cookie Book" at the library, I literally laughed out loud and stopped in my tracks. Minnesota is the home to Land O' Lakes butter, Betty Crocker cookie mixes, and the masters of baked goodies--General Mills' Chex and Cheerios cereals.

With uber-cold winters that last from September to May, the fine bakers of Minnesota have a looooong season to spend cozied up in their kitchens.

If ANYONE knows a good cookie, it has to be a Minnesotan. I grabbed that cookbook off the shelf so fast it made my girls' heads spin.

Crunchy peanut butter cookies are perfect for baking cookie sandwiches with kids.

Flipping through the pages of the cookbook, I spotted these crunchy peanut butter cookies sandwiches and paused. As much baking as I've done over the last year for The Ultimate Kids' Baking Book, I couldn't remember the last time I made a simple but glorious peanut butter cookie.

My mom didn't bake a ton when we were young, but she made amazing peanut butter cookies as part of her rotation. I don't know why they aren't a more steady part of our baking habits. I realized my girls have probably never had one aside from our favorite peanut butter blossom cookies.

I'm all about the texture lately. As much as I love classic peanut butter cookies, I was totally drawn to this recipe because it features two super-thin crunchy peanut butter cookies sandwiched together with a smooth and creamy peanut butter filling.

Two cookies into one peanut butter cookie sandwich?? Isn't that a bit much?

I was initially worried the peanut butter cookie sandwiches would be too much cookie for us. Pairing up two cookies into one seems like overkill, but since each half of the sandwich is actually so thin and we spread just a thin amount of filling in between, they ended up being simply perfect.

The peanut butter cookies are crunchy but still chewy, exactly how I love them.

Are these peanut butter cookies too peanut butter-y?

I was also worried the cookies would have too much peanut butter flavor. The Peanut only likes peanut butter in fluffernutter sandwiches. She's not a huge fan of the texture or strength of the peanut butter on its own. She won't even eat Reese's Peanut Butter Cups. Crazy, I know.

The peanut butter filling is mixed with powdered sugar and just a tiny bit of dried ginger which gives it a little tiny kick and keeps it from being too peanut butter-y. I can't believe I just said that, is that really a thing?? I guess it is for her.

She took one bite and her eyes went super wide. She absolutely LOVED them. When I asked why these were ok when other peanut butter things are not, she said it was because they were sweeter than just straight-up peanut butter. She also adored the crunchy texture, just like me.

How to make the best-ever crunchy peanut butter cookies sandwiches with kids:

Get your little bakers involved with preparing these peanut butter cookies. There are so many tasks even the youngest kids can help with:

  1. Put them in charge of measuring and chopping the peanuts in a food processor.
    (Nervous to let them chop? Check out my tips here.)
  2. Have them pat and form the cookie balls into flat discs on the cookie sheets.
  3. Hand them a spatula and leave them in charge of mixing the filling.
  4. Ask them to pair up matching sized cookies for the sandwiches.
  5. Work together to spread the filling and form the sandwiches.

Peanut Butter Cookie Sandwiches

Thin and crunchy peanut butter cookies are filled with a sweet peanut butter frosting and turned into the tastiest cookie sandwiches you've ever had! Don't forget a tall glass of milk to go with them. Adapted from The Great Minnesota Cookie Book.
TOTAL TIME 1 hour 40 minutes
PREP TIME 30 minutes
Additional Time 1 hour
COOK TIME 10 minutes
YIELD 2 dozen cookie sandwiches

Ingredients
  

  • 1 1/4 cup roasted peanuts
  • 3/4 cup flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 3 tbsp butter melted
  • 1/2 cup creamy peanut butter
  • 1/2 cup sugar
  • 1/2 cup packed light brown sugar
  • 3 tbsp milk
  • 1 egg

For the filling:

  • 3 tbsp butter
  • 3/4 cup creamy peanut butter
  • 1 cup powdered sugar
  • 1/2 tsp ground ginger

Instructions

  • Add the peanuts to the bowl of a food processor and pulse them until they are finely chopped. (Or you can chop them by hand.) Set them aside. 
  • Whisk together your dry ingredients in a medium sized bowl: flour, baking soda, and salt. Set aside.
  • Add the butter to a microwave-safe container and heat it until melted. Add the melted butter, peanut butter, sugar, and light brown sugar to the bowl of a mixer with the paddle attachment and beat until everything is combined. Add the milk and the egg and beat to combine. Add the chopped peanuts and stir until just combined. Scrape the cookie dough off the beater and then cover it with plastic wrap. Chill the cookie dough in the fridge for at least one hour.
  • Preheat the oven to 350°F. Line baking sheets with parchment paper or a silicon mat.
  • Use a small spoon to scoop just a 1/2-inch sized ball of dough onto the prepared cookie sheets. Gently pat the dough ball into a flat, 1-inch round disk. The more uniform your discs, the easier matching up cookies for the sandwiches will be.
  • Bake until the cookies are slightly toasted looking, about 10 - 13 minutes.
  • Let the cookies cool completely before assembling them into sandwiches.

Prepare the filling:

  • Add the butter to a microwave-safe container and heat until melted, about 30 seconds. Pour the melted butter into a medium-sized mixing bowl. Add the peanut butter, powdered sugar, and ground ginger. Gently stir the ingredients together with a spatula. The filling will become thick like play dough. Use the back of your spatula to smush and flip the filling until the powdered sugar is completely incorporated into the peanut butter. 

Assemble the cookies:

  • Match your baked cookies up into similar sized pairs. Use a butter knife to spread a generous dollop of filling onto one cookie and then add the second cookie to form the sandwich. Press gently so the filling meets the edge of the cookies.
