In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.

Use a stand mixer fitted with the beater blade attachment to beat the butter and sugars together until smooth. Add the eggs and vanilla extract and mix until combined.

Add the dry ingredients and mix on low until just combined. Don’t over mix. Stir in the pretzels, potato chips, oats, chocolate chips, and M&M’s.

Roll the cookie dough into balls, about 2 tablespoons per cookie. Place on prepared baking sheet, 2-inches apart. Bake for 10 to 12 minutes or until cookies are slightly golden brown around the edges, but still soft in the center. Don’t over bake.

Remove from the oven and sprinkle with flaky sea salt. Let the cookies cool on the baking sheet for 5 minutes. Transfer to a cooling rack and cool completely.
