We have done this before when we focused on the Christmas story through the eyes of the wise men, discussing the traditions of many cultures who celebrate the wise men coming and bringing gifts to the child Jesus.
One year we used a "real" recipe -- it was delicious, but very involved. We did it as a supplemental activity, not during our normal SS time. We actually took orders from the congregation ahead of time and sold the cakes as a fundraiser for a mission project.
We've used crescent roll dough to make simplified versions that can easily be done during a 45-60 minute class session. Tear off the dough into rectangles (not triangles) and give each child a rectangle. Have them press the perforations together to make one solid rectangular piece. Brush with melted butter and bake according to directions. When done, brush lightly with more melted butter and sprinkle with green, gold and purple colored sugar!
Easy, festive and yummy too!
