  1. Preheat the oven to 325°F with a rack in the upper third. Lightly grease (or line with parchment) two baking sheets.

  2. Beat together the butter, peanut butter, and baking sugar alternative until smooth.

  3. Mix in the egg and vanilla.

  4. Add the flour, baking soda, and salt, beating gently until everything is well combined.

  5. Drop the dough by tablespoonfuls onto the prepared baking sheets (a tablespoon cookie scoop works well here), leaving 2" between them.

  6. Use a fork to flatten each cookie to about 1/2" thick, making a cross-hatch design.

  7. Bake the cookies for 10 to 12 minutes, until they’re set and the edges are barely beginning to brown; the tops won't have browned. Remove them from the oven, and cool on a rack.
