Preheat oven to 350°F (177°C). Line 2 baking sheets with parchment paper.
In a bowl, whisk 2 ¼ cups all-purpose flour, 1 teaspoon baking soda, ½ teaspoon baking powder, and 1 teaspoon salt.
In a large bowl, beat 1 cup unsalted butter, 1 cup brown sugar, and ½ cup granulated sugar until fluffy (about 2 minutes). Add 2 large eggs and 2 teaspoon vanilla extract; beat well.
Gradually stir in the dry mixture until just combined.
Fold in ½ cup M&M's, ½ cup pretzels, ½ cup potato chips, ½ cup semi-sweet chocolate chips, ½ cup white chocolate chips and 2 tablespoons sprinkles. Dough will be chunky.
Scoop heaping tablespoons (or use a medium cookie scoop) onto baking sheets, spacing 2 inches apart. Bake 10–12 minutes, until edges are golden but centers look slightly soft.
Let cookies rest on baking sheet for 5 minutes before transferring to a wire rack.
