Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper.
In a medium bowl, mix together the peanut butter, granulated sugar, egg, and baking soda until a dough forms.
Roll the dough into 12 equal-sized balls and place them on the prepared baking sheets, spacing them about 2 inches apart.
Flatten each ball slightly with the palm of your hand.
Bake the cookies for 10 to 12 minutes until they are set but still soft. Remove from the oven and allow to cool completely on the baking sheets.
Once cooled, decorate each cookie to look like a turkey:
Attach 2 mini pretzel twists to the back of each cookie using a small dab of orange icing to create the turkey’s feathers.
Place 1 candy-coated chocolate egg at the base of the pretzels on each cookie to form the body feathers, securing with a small amount of icing if needed.
Use red icing to pipe a small wattle on the front edge of the cookie.
Use orange icing to create a small beak just above the wattle.
Attach 2 small candy eyes above the beak using a tiny dot of icing.
Allow all icing decorations to set before serving.
