3-Ingredient Peanut Butter Cookie with Sea Salt in 15 Minutes

Instructions:

1. Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper. In a mixing bowl, whisk the large egg vigorously for 30 seconds until it is pale, frothy, and streak-free to create a stable protein matrix.
2. Add the creamy peanut butter and granulated sugar to the whisked egg. Use a sturdy silicone spatula to fold the ingredients together until a cohesive dough forms and pulls away from the sides of the bowl. Let the dough rest for 2 minutes if it appears too oily.
3. Scoop rounded tablespoons of dough and roll them into 1-inch balls. Place them 2 inches apart on the prepared baking tray. Use the tines of a dinner fork to press a criss-cross pattern into each ball, flattening them to a 1/2 inch thickness.
4. Bake for 8 to 10 minutes. The cookies are finished when the edges are set and slightly bronzed. Remove from the oven and immediately sprinkle with flaky sea salt while still warm to ensure adherence.
