Place flour, baking soda and salt in a large mixing bowl, and stir to combine. Set aside.
Cream together softened butter, sugar, and brown sugar in the bowl of a stand mixer until it becomes light and fluffy, about 3-4 minutes on high speed.
Add the egg and vanilla and combine with creamed butter and sugars.
With mixer on low speed, slowly stream in all of the oil. Increase speed to high and keep blending until it's completely incorporated with the other ingredients, about 2-3 minutes. Scrape down the sides of the bowl with a rubber spatula as needed.
Reduce speed to low again and slowly add dry ingredients to the bowl. Keep mixing until the flour mixture is fully incorporated and you have a smooth batter.
Using a wooden spoon or rubber spatula, stir in crispy rice cereal, rolled oats, chopped pecans, toffee pieces, white chocolate chips, and shredded coconut.
Using a cookie dough scoop, scoop dough out onto a cookie sheet and refrigerate dough for 2 hours.
Preheat oven to 325℉.
Transfer refrigerated balls of dough onto a silpat or parchment lined cookie sheet about 2 inches apart. Do not crowd cookies, they will spread while baking.
Sprinkle the top of each cookie with a pinch of sea salt.
Bake for 16-20 minutes or until cookies are a light golden brown along the edges.
Remove from oven and allow cookies to cool for 5 minutes on the cookie sheet.
Transfer cookies to a rack and allow them to cool to room temperature. Cookies will initially be very soft but will firm up as they cool.
