Ingredients
Method
Preheat oven to 350°F (175°C) and line a baking sheet.
Cream butter, peanut butter, brown sugar, and granulated sugar until smooth.
Add egg and vanilla extract, mixing until fully combined.
In a separate bowl, whisk flour, baking soda, and salt.
Gradually mix dry ingredients into wet ingredients until just combined.
Scoop dough into balls and place on baking sheet.
Press each ball lightly with a fork to create a crisscross pattern.
Sprinkle with flaked sea salt.
Bake for 9–11 minutes until edges are set and centers are soft.
Let cool before serving.
Notes
Do not overbake—cookies should look slightly soft in the center when removed. Store in an airtight container for up to 4 days. Microwave briefly to soften if needed.
