Place the softened cream cheese into a medium mixing bowl. The cream cheese should be fully softened so it blends smoothly without lumps, creating a uniform base for the cheesecake texture.
Add the creamy peanut butter to the bowl with the cream cheese. Using a sturdy spoon or spatula, begin mixing until the two ingredients are thoroughly combined. The mixture should become thick, smooth, and evenly colored with no visible streaks of plain cream cheese.
Gradually add the powdered sugar to the mixture. Incorporate it in stages, mixing well after each addition to avoid clumping and ensure a smooth, velvety consistency. As the sugar blends in, the mixture will become sweeter and firmer while maintaining a creamy texture.
Once fully combined, the mixture should be thick enough to hold its shape. Using clean hands or a small scoop, portion the mixture and gently roll it between your palms to form compact, smooth balls. Shape each piece evenly so they are uniform in size and appearance.
Place the rolled cheesecake balls on a clean, flat surface such as a plate or tray. Chill as needed until the balls feel firm to the touch and hold their shape well for serving.
