Ingredients
Scale
- 1 cup (250 g) creamy peanut butter
- 1 cup (200 g) granulated white sugar
- 1 large egg (room temperature)
Instructions
- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
- Mix the peanut butter, sugar, and egg in a medium bowl using a fork or spoon until a uniform dough forms, about 2-3 minutes.
- Roll the dough into small balls, roughly 1 inch (2.5 cm) in diameter, yielding about 18-20 cookies.
- Place the balls on the prepared baking sheet, spacing about 2 inches (5 cm) apart.
- Press each ball gently with a fork to create a crisscross pattern.
- Bake for 10-12 minutes until edges are set but centers remain soft.
- Remove from oven and let cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Use creamy peanut butter for best texture; natural peanut butter should be stirred well before measuring. Avoid overbaking to keep cookies soft and chewy. Let cookies cool on the baking sheet before transferring to avoid crumbling. Optionally add ½ teaspoon vanilla extract or a pinch of salt to enhance flavor. For vegan version, substitute egg with a flax egg (1 tbsp ground flaxseed + 3 tbsp water).
