After the dough has risen for 2 hours, punch down.
On a floured surface, roll your dough into a 9x12 rectangle.
Evenly spread prepared brown sugar pecan filling on the rectangle.
Starting at the long end roll up into a large tube.
Place on the prepared surface of your cookie sheet in an oval ring. Place seam side down and pinch the ends together to make a complete oval.
With a sharp knife, cut into the ring just down to the filling in one-inch intervals.
Let rest and rise for 45 minutes. Preheat the oven to 350° while oval ring is resting.
Bake for about 25-30 minutes in a 350° oven. You will know it is done when it is lightly browned on top.
If desired, brush about 1 Tablespoon melted vegan butter on the top of the baked king cake.
If you haven't already made the icing, make it now. See instructions above.
Transfer the baked king cake to your serving platter. Don't forget to tuck the baby into the baked king cake!
Pour icing on top (see directions in post for wax paper trick).
Sprinkle colored sugar in a pattern around the ring.
Party on! Whoever finds the baby in their slice has good luck for a year and gets to host next year's Mardi Gras party! Really! It's the rule:)
