To prepare a valentine conversation heart cookies recipe, first you need to gather your ingredients. First, you will need your cookie dough. You can use any cookie recipe that you have on hand, or you can make your own. Then, preheat your oven to 350 degrees F (180 degrees C) and prepare your baking sheet by lining it with parchment paper. Next, add your chocolate chips to the bowl of your mixing bowl and mix them with your hands until the chocolate is completely melted. Now, pour your mixture into the prepared cookie sheet and bake the cookies for 10 to 12 minutes or until they are lightly browned. Allow your cookies to cool completely before removing them from the oven.
