In a medium mixing bowl, gently mix together the butter substitute and the peanut butter. Once they are well blended, you can add the sugar or sweetener and mix to combine.

Next, add the egg and vanilla, followed by the dry ingredients. Stop mixing once everything is evenly distributed and the dough comes together (refer to tips if it is dry).

Use a tablespoon measuring spoon to scoop 20 cookie balls. Roll them into a ball and place them on the tray with some space in between. Then gently press them down with your hand before baking.

Bake the cookies for 8-10 minutes or until they barely turn from shiny to matte (watch closely during this time window). While they bake, unwrap the Hershey's kisses so they are ready to go.

After removing the cookies from the oven, immediately top each one with a Hershey's Kiss before the cookies set. If your kitchen is a warm environment, you can keep the chocolates in the refrigerator or freezer before topping the cookies to prevent them from melting too much.
