• Place the creamy peanut butter in a large bowl.
• Add the powdered sugar and mix well using a spoon or spatula so the peanut butter and powdered sugar are combined well.
• Knead well using your hands to form the peanut butter cookie dough.
• Chill the prepared the cookie dough in refrigerator for a couple of hours.

To bake the cookies:

• Preheat oven to 375 degree Fahrenheit.
• Prepare a baking sheet lined with parchment paper or foil.
• Make small balls out of cookie dough (you may apply little oil in your palms if you feel the dough is sticky to handle) and place them in the baking sheet. Make sure to leave enough space between the cookie dough balls.
• Using a fork, press the dough balls and make criss cross patterns on top (this basically helps the cookies to flatten easily). These peanut butter cookies don't spread on their own as they bake so it's important you flatten them out before baking.
• Place the baking sheet in the preheated oven and bake for 12 to 15 minutes until the cookies are beginning to brown on the sides.
• Once the cookies are baked, immediately transfer the baking sheet from the hot oven and allow the cookies to cool down (they are too hot at this point and can cause burn if touched, so make sure not to touch the cookies before they cool down).
• The cookies will harden in texture as they cool down. For best results, once the cookies are almost room temperature, place them in the refrigerator and chill for another 30 minutes which will help them to nicely firm up.
• These 2 ingredient peanut butter cookies are super soft and fudge like in texture.
• Enjoy the cookies with a cup of warm milk, hot tea or coffee as you like!
