Combine all ingredients in a large bowl and mix until ingredients begin to form a doughy substance. You may need to add more water if your ingredients will not form together into a ball.
Use your hands to mold ingredients into a ball.
Place on wax paper and roll out dough with a rolling pin.
Once rolled out to about ½ inch thick, use a gingerbread man cookie cutter to cut out the treats.
Place on a greased pan and cook for about 45 minutes, flipping the treats over halfway through.
While treats are cooling, place a bit of heated peanut butter in a squirt bottle and use it to draw the eyes, mouth, and buttons, if desired. Make sure to not make the peanut butter too runny.
