These peanut butter and jelly thumbprint cookies are a combination of salty and sweet. For this recipe I used C&H® dark brown sugar to add a deep, rich molasses flavor which also adds moistness. The dark brown sugar makes this tender peanut butter cookie melt in your mouth and when it's paired with the sweet jam, makes this cookie irresistible and sets this snack over the top. Peanut butter thumbprint cookies are perfect for both beginners and seasoned bakers. It's a simple recipe with a big impact of nostalgic flavors.
