Preheat your oven to 350 degrees and spray the inside of a bundt pan with non-stick baking spray.
Remove the cinnamon rolls from their tubes and cut each biscuit in half and then in half again so you have four pieces from each biscuit.
In a medium sized bowl add the brown sugar, diced pecans, and a dash of salt.
Stir to combine. In a separate small bowl, add the butter and melt.
Add the vanilla to the melted butter and stir to combine.
Start by taking one piece of cinnamon roll, dipping it in the melted butter and then rolling it through the sugar mixture.
Lay the pieces in the bottom of the bundt pan and continue until all pieces are used.
Place the bundt pan on a baking sheet and place in the center of the oven. Bake for 40 - 45 minutes.
Remove from the oven and let sit for 15 minutes.
Place a cake stand upside down on the top (bottom) of the bundt pan. Slowly flip both the cake stand and the pan upside down.
Slowly begin to remove the bundt pan from your monkey bread. The monkey Bread should slide right out. Let cool completely.
In a small bowl add the powdered sugar, milk and vanilla. Whisk until fully combined and smooth.
Drizzle the glaze over your monkey bread. Sprinkle the green, yellow, and purple cake sprinkles on top. Serve immediately.
