What is a exactly is a Muffin Tin Meal? Pretty simple here. It's a meal, snack, or dessert served in a muffin tin. For Muffin Tin Mondays we make them for our kids, but anyone can have a muffin tin meal! A muffin tin is also known as a muffin pan, cupcake tin or cupcan pan and for our purposes here, we also use silicone and paper baking cups, pans and tins.
