Preheat the oven to 350 degrees and line a 9x13” pan with parchment paper and lightly spray with cooking spray.

In a medium sized microwave safe bowl, combine butter, sugar, chocolate pudding, and salt.

Heat in 30 second increments and then stir until the butter and sugar combine together - mixture will be grainy (I heated mine two times).

Mix in eggs one at a time and add the vanilla. Beat mixture really well with a fork, about 60 times.

Add the flour and mix well.

Pour the batter into the prepared pan and bake for 25 minutes - the top of the brownie will be set and the inside of the brownie will still jiggle.

Sprinkle half of each of the chocolate chips, marshmallows, coconut flakes, and M&Ms.

Pour sweetened condensed milk on top and spread evenly.

Add the rest of the chocolate chips, marshmallows, coconut flakes, M&Ms, and sprinkles.

Bake for another 23-27 minutes.

Let cool completely, and cut the edges off (optional).

Cut into bars, and enjoy!
