King Cake Bubble Up - We loved this!! Cinnamon rolls, eggs, milk, vanilla and cream cheese. Ready in 30 minutes. Better than any store-bought King Cake we've had! Can serve warm or room temperature. We ate way too much of this! Perfect for your Mardi Gras party!
Preheat oven to 375ºF. Lightly spray a 9x13-inch pan with cooking spray.
Separate cinnamon rolls, save icing to use after the bubble up is baked. Cut each cinnamon roll into 4 pieces. Place in bottom on prepared pan.
Using a hand held electric mixer, beat together cream cheese and sugar. Add eggs and vanilla, mixing well. Add milk and mix until combined. Pour over chopped cinnamon rolls.
Bake for 30 to 35 minutes. Remove from oven and cool for 5 to 10 minutes. Spread cinnamon roll icing over top of casserole. Sprinkle with colored sugar.
