Flourless peanut butter and fluff cookies. A perfectly balanced cookie with pockets of gooey sweetness throughout, complementing the rich peanut butter flavor.
In a heatproof bowl, combine the light corn syrup and powdered sugar.
Place the bowl over a pot of simmering water, making sure the bottom of the bowl doesn't touch the water.
Stir the mixture constantly until the powdered sugar is completely dissolved and the mixture is hot to the touch, about 3-5 minutes. Remove the bowl from the heat.
In a separate clean mixing bowl, beat the egg white until stiff peaks form.
Gradually pour the hot sugar syrup into the beaten egg white while continuing to beat on high speed.
Continue beating until the mixture is thick, glossy, and holds its shape, about 5-7 minutes.
Add the vanilla extract and beat for another minute to incorporate.
Making Peanut Butter and Fluff Cookies
Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it.
In a large mixing bowl, cream together the peanut butter and sugar until smooth.
Beat in the egg and vanilla extract until well combined.
Gently fold in the marshmallow fluff until it's swirled throughout the dough.
Roll tablespoon-sized balls of dough
Place the dough balls onto the prepared baking sheet, spacing them about 2 inches apart. Using a fork, press down gently on each dough ball to create a crisscross pattern.
Bake for 8 to 10 minutes, or until the edges are lightly golden brown.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Notes
For uniform cookie sizes, use a cookie scoop. This ensures even baking and helps maintain shape during cooking
