Peanut butter & jelly cookies are soft peanut butter cookies with sweet jam throughout. The cookies can be made in less than 30 minutes with no chilling necessary.
Preheat oven to 350 degrees F. Line baking sheets with parchment paper. Set aside.
In the bowl of your stand mixer fitted with the paddle attachment or in a large bowl with a hand mixer, add butter, brown sugar, and granulated sugar. Beat until well combined, about 2-3 minutes.
½ cup salted butter, ½ cup light brown sugar, ½ cup granulated sugar
Add peanut butter, egg, and vanilla. Mix again until incorporated.
1 cup peanut butter, 1 large egg, 1 teaspoon vanilla extract
Add flour, baking powder, and salt. Stir in until just combined.
1 ½ cups all purpose flour, ¾ teaspoon baking powder, ½ teaspoon salt
Scoop 1 ½ tablespoons of dough and roll into a ball.
Using a finger, create a small well in the center. Add about ¼ teaspoon jam to fill the well.
Pinch the dough back to try to seal in the jam. Roll back into a ball. Don’t worry if they’re a bit messy.
Repeat until all dough is used, and place dough balls at least 2 inches apart on the prepared baking sheets.
Bake for about 8-10 minutes. The cookies should be set but still look soft in the centers. Let cookies cool completely on the baking sheet.
Notes
Butter: If you would like to use unsalted butter, increase the salt to 3/4 teaspoon.
Peanut butter: You'll want peanut butter like Jiff or Skippy for this recipe. I don't recommend using natural peanut butter in this recipe.
Flour: You can weigh the flour (click "metric" just above the ingredients) or sift, lightly spoon into a measuring cup, and level without packing.
Jam: It's important to use jam and not jelly. Jam is thicker, and jelly can melt during baking.
