Cheddar Cheese Puffs with Jalapeño Raspberry Jam is great as an appetizer or a snack. Just be careful because they are very addicting with a buttery flaky pastry and a chewy cheddar cheese center. Okay, so the picture doesn't look too "puffy." We went a little overboard on the amount of cheese and jam we put inside, so when it baked it stayed a little flat. So, if you want a beautiful puffy outcome, follow the recipe below as-is. If you love cheese like we do, and put more in, this is what they will look like :)
