This is an easy bear muffin recipe that only requires Oreos and milk, and can be made by simply mixing and microwaving. Crush the Oreos finely in a resealable bag, add milk, and knead to make the batter. Pour the batter into muffin cups, attach ears made from chocolate chip cookies, and heat in the microwave. Once baked, decorate with chocolate pens or langue de chat cookies to create cute bear faces. These adorable muffins have a chewy and moist texture and are perfect for making with children or as a gift.
