Preheat the oven to 300 degrees F (150 degrees C). Sift all-purpose flour, baking soda, and salt together in a bowl.

Sifting dry ingredients ensures a light and uniform texture in your cookies.📌

Beat unsalted butter, creamy peanut butter, and crunchy peanut butter together in a large bowl until smooth. Beat egg white and white sugar into butter mixture until smooth. Add whole egg and brown sugar; continue to beat until smooth. Gradually stir the sifted all-purpose flour mixture into the butter mixture until the batter is well mixed.

Ensure butter and peanut butter are at room temperature for easier and smoother mixing.📌

Roll dough into 1 1/4-inch balls and place 2 inches apart onto ungreased baking sheets. Press balls with a fork creating a crosshatch. Freeze cookie dough on baking sheet until dough is firm, 5 to 8 minutes.

Freezing the dough briefly helps the cookies hold their shape and prevents excessive spreading during baking.📌
