Step 1: Preheat & Prepare Baking Sheets

1. Preheat your oven to 350°F (175°C).
2. Line two baking sheets with parchment paper and set aside.

Step 2: Cream Butter & Sugars

3. In a large mixing bowl or stand mixer, beat together butter, brown sugar, granulated sugar, and turbinado sugar on medium-high speed until light and fluffy (about 3-4 minutes).

Step 3: Add Wet Ingredients

4. Add egg and vanilla extract, then mix until fully incorporated.

Step 4: Prepare the Dry Ingredients

5. In a food processor or blender, pulse the oats a few times to create a mix of oat flour and slightly larger oat pieces.
6. In a separate bowl, whisk together flour, pulsed oats, baking soda, and salt.

Step 5: Combine the Dough

7. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined.
8. Fold in Rice Krispie cereal, chopped Nestle Crunch Bar, and semi-sweet chocolate chips using a spatula or wooden spoon.

Step 6: Scoop & Shape Cookies

9. Using a ¼ cup cookie scoop, portion the dough into large balls and place them on the prepared baking sheets.
10. Press a few extra pieces of chocolate and Rice Krispies on top for a bakery-style look.
11. Sprinkle a light pinch of flaked sea salt on top.

Step 7: Bake the Cookies

12. Bake in the preheated oven for 11-13 minutes, or until the edges are golden brown but the centers are still soft.
13. Remove from the oven and immediately sprinkle a little extra sea salt on top if desired.

Step 8: Cool & Serve

14. Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
15. Enjoy warm or at room temperature!
