Move the rack in the oven to the lowest setting. Preheat the oven to 350°F.
Crack the egg into a large bowl and whip it with a fork until scrambled.
Add the honey to the egg and mix with a fork until well combined.
Add the baking soda to the egg mixture and mix well with a fork.
Add the peanut butter to the egg mixture and mix it in with a fork until it's all combined. The entire mixture should look like peanut butter straight out of the jar. If it's not combing, stir rapidly in the opposite direction. Continue to switch directions until combined.
Scoop 2½ to 3 tablespoons worth of batter onto a metal cookie sheet. Using the back of a spoon or fork, spread the batter into a circle about 2½ to 3 inches wide and ½-inch thick. (The cookies will spread just slightly when baking, so however you spread them by hand will be what they look like after baking.)Scoop all the batter into cookies, placing them at least one inch apart.
Place the cookie sheet in the oven on the bottom rack and bake for 10 minutes.
After 10 minutes, remove the cookie sheet from the oven and allow the cookies to cool on the sheet. When cooled, lift the cookies from the sheet with a spatula.
