Buttery Sweet Cookie Stack (Print Version)

# Ingredients:

→ For the cookies

01 - ½ teaspoon baking soda
02 - ¼ teaspoon salt
03 - 1 large egg
04 - 1 cup creamy peanut butter
05 - ½ cup granulated sugar
06 - ½ cup brown sugar, packed
07 - 1 ½ cups all-purpose flour
08 - ¾ cup unsalted butter, softened
09 - 1 teaspoon vanilla extract

→ For the filling

10 - 2 tablespoons unsalted butter, softened
11 - ¾ cup creamy peanut butter
12 - 1 teaspoon vanilla extract
13 - 1 ½ cups powdered sugar

# Instructions:

01 - Set the oven to 350°F (175°C). Cover two baking trays with parchment paper.
02 - Stir together the salt, baking soda, and flour in a medium bowl. Put it aside for later.
03 - Cream the unsalted butter, peanut butter, white sugar, and brown sugar using a big bowl until it's silky smooth.
04 - Toss the egg and vanilla into the wet stuff, blending until it all comes together. Gradually, stir in the dry ingredients until just mixed.
05 - Roll dough into balls (about one tablespoon each), then pop them onto the parchment-lined trays with about 2 inches in between. Press down the tops with a fork to make criss-cross patterns.
06 - Let the cookies bake for 10-12 minutes, or until they just brown around the edges. Let them cool for 5 minutes on the tray, then move them to a rack and cool completely.
07 - Whip together the powdered sugar, softened butter, peanut butter, and vanilla in a bowl until the mixture is totally blended and creamy.
08 - Once the cookies are no longer warm, spread some filling onto the flat side of one cookie. Close it with another cookie to make a little sandwich.
09 - Store these sandwiches in a sealed container at room temperature.

# Notes:

01 - Make sure both the butter and peanut butter are softened to room temperature to get the perfect texture.
02 - If you'd like a stronger flavor, throw a pinch of salt into the filling.
03 - Sticky dough? No problem. Chill it in the fridge for 30 minutes so it's easier to work with.
04 - Drizzle melted chocolate over the sandwiches if you're craving a chocolatey twist.
05 - Keep these cookies fresh in an airtight container for up to seven days.
