1 ⅔cupall-purpose flour -- if you don't have a scale, stir the flour to aerate before measuring**(210 grams)
½teaspoonbaking powder
¼teaspoonsalt plus a pinch
6tablespoonsunsalted butter, softened(85 grams)
½cupgranulated sugar(100 grams)
¼cupbrown sugar(50 grams)
1teaspoonvanilla extract
1largeegg(50 grams)
⅓cuplight corn syrup(110 grams)
5brokenOreos, broken into chunks
1 ½cupsmix of dark chocolate and white chips
Any other chocolate you like -- maybe Oreo Cookies & Cream bar, broken up?
Instructions
Preheat oven to 350ºF. Line two baking sheets with parchment paper or a Silpat. Do not use butter or cooking spray, as this may cause the cookies to spread a bit.
Melt the unsweetened chocolate in the microwave using 50% power and stirring every 30 seconds. Let it cool.
Mix the flour, baking powder and salt together in a separate bowl and set aside.
With an electric mixer, beat the butter and both sugars until light and creamy. Beat in the corn syrup and vanilla, scraping the sides of the bowl often. Beat in the melted chocolate.
Add the egg and beat for another 30 seconds. With a heavy duty scraper, fold in the flour mixture and stir until blended.
Stir in the chocolates and the broken cookies.
Using a medium size cookie scoop, scoop dough onto the trays (or scoop onto plastic wrap lined plates and cover if you wish to bake later) spacing 2 inches apart. You should get about 20 large balls of dough using the medium scooper.
Bake on center rack, one sheet at a time, at 350 degrees for 10 to 12 minutes or until they appear set and are less shiny. You can also use convection, in which case it will probably take around 10 minutes. Ovens vary.
Let cool on the baking sheets for about 10 minutes, then transfer to a wire rack and let cool completely or transfer to the refrigerator and chill if you like a firmer, colder, cookie.
Notes
Tip: If you don't have a scale and can't weigh the flour, use a light hand when measuring by volume. That is, spoon the flour into the cup and level off. Also, you may want to make one or two test cookies just to nail down the proper baking times. I've been baking them for 10 minutes at 350F using convection.
