Vegan Santa's Trash Cookies

1 Preheat the oven to 350 degrees(F).
2 First, make a flax egg by whisking the flax meal and water together in a small bowl and set aside to thicken while you start the cookie batter.
3 Using a hand mixer or stand mixer, mix together the vegan butter, cane sugar and brown sugar in a large mixing bowl. Mix until fully combined and fluffy. Scrap down the sides of the bowl if needed.
4 Then add the vanilla and the flax egg you made. Then continue to mix until everything is fully combined. Set aside.
5 Now, in a separate large mixing bowl, sift the flour and the baking soda. Then add in the salt. Stir to combine.
6 Next, add about 1/2 cup of the dry ingredients to the wet ingredients at a time, mixing until the dry ingredients are combined, then add more, until all of the dry ingredients have been incorporated. 
7 Then, pour the crushed chips, dark chocolate chips, crushed pretzels and sprinkles into the batter. Fold everything in so they are evenly distributed into the batter. 
8 Line a large baking sheet with parchment paper or spray with non-stick spray. Then take about 1-2 tablespoons of the cookie batter and roll into a ball. Place on the baking sheet and press down to flatten just a bit. They should still be thick. 
9 Repeat with all of the batter making sure the cookies are at least 2 inches apart on the baking sheet, sprinkle the tops of the cookies with sea salt if desired. You will probably need to use 2 baking sheets or do them in 2 batches. 
10 Bake for 7-9 minutes or until golden brown. They will still be slightly soft when done, they firm up when cooled. Cool completely before eating.
