Before I was a Christian, there was a wonderful Christian girl in my school who honored Jesus at every turn. She gave me a tin of these amazing buns that later I made for my kids and called "Resurrection Buns." My family loves them! Thank you, Jamie McElvaney!
So these rolls...yum!...are doughy and round (like a tomb). You wrap the dough around a marshmallow, dip it in melted butter, roll it in cinnamon/sugar, and then bake. The marshmallow becomes a sweet syrup on the inside, but the roll stays round. When you serve them to your kids, they bite into the roll and discover that it's empty--just like Jesus' tomb was on Easter morning.
So, there are two ways to make them. If you really like the whole process of making yeast dough, use the "Resurrection Buns" recipe here: http://tinyurl.com/yclydh2
If you prefer an easier approach, look for "Empty Tombs" here: http://tinyurl.com/ybu2sgb
By the way, you'll see a lot of other great Easter week ideas at these links, too.
