Rocky Mountain Chocolate Factory's Kitchen Sink Cookie Recipe


If you've been following our blog for a while, you've noticed one thing is for certain- we are fanatical when it comes to chocolate. However, we are ALSO fanatical about anything containing chocolate...which is why we are head-over-heels in love with these Kitchen Sink cookies. They're the perfect combination of crunchy and chewy, salty and sweet... it's no surprise that they didn't last long around here... they're a hit! These cookies make the perfect treat for an evening in, or look great on a platter for a party. Want to try them yourself? Here is what you'll need:


  • 3/4 cup brown sugar
  • 1/2 cup white sugar
  • 3/4 cup butter
  • 1 large egg
  • 1 Tbsp. vanilla
  • 2 cups flour
  • 1 Tbsp. corn or tapioca starch
  • 1 tsp. baking soda
  • 3/4 tsp. kosher salt
  • 1 1/2 cup of your favorite candies or mix ins (we used crushed up Rocky Mountain Chocolate Factory dark chocolate Bavarian pretzels, English toffee, milk chocolate covered potato chips, milk chocolate covered graham crackers and oats).
  • A sprinkle of sea salt


  1. Preheat oven to 350 F (we bumped it up to 375 F for high altitude)
  2. Cream together 3/4 cup brown sugar, 1/2 cup white sugar, and 3/4 cup butter. 
  3. Add large egg and Tbsp. vanilla and mix until well incorporated. 
  4. In a separate bowl, whisk together two cups flour, 1 Tbsp. corn (or tapioca) starch, 1 tsp. baking soda, and 3/4 tsp. kosher salt. 
  5. Add dry ingredients to the sugar/butter/egg mixture and stir until dough forms.
  6. Gently stir in 1 1/2 cup of your favorite candies or mix ins. 
  7. Once evenly spread through the dough, drop dough by heaping tablespoon onto silicone or parchment lined baking sheet. 
  8. Sprinkle dough with sea salt. 
  9. Bake for 8-9 minutes or until edges are just golden. 
  10. Let cool for 3-5 minutes on cookie sheet then transfer to wire rack to finish cooling. 
  11. Store in an air tight container for 3-4 days (if they last that long 😊)
