Grab a medium mixing bowl and toss in the flour, cornflour, soda, and salt. Give it a good stir and leave it to the side for later.

In a bigger bowl, blend together the softened butter, brown sugar, and white sugar until it’s pretty smooth. Stir in the vanilla along with the egg on low until it comes together.

Slowly add the dry mixture into the wet mixture, keeping your mixer on low. Stop as soon as it's combined, even if some streaks of flour remain.

Carefully stir in the chocolate bits, chunks, and the shaved dark chocolate. Give it just a brief stir to mix them in evenly.
05 -
Pop the dough in the fridge, covered, for a little over an hour. This keeps the cookies from spreading too much when baking and lets flavors blend.
06 -
Heat your oven to 350°F (175°C). Lay some parchment over your baking trays.
07 -
Form balls of dough about 1 inch wide, spacing them about 2 inches apart on the trays. If you’re feeling fancy, add some extra chocolate bits to the top of each one.

Bake cookies for 8-10 minutes. Edges will turn slightly golden while centers stay soft—just right for chewy cookies.

Leave cookies on the trays for 10 minutes to firm up a bit. Then move them to a rack to cool completely.

Once cooled, keep cookies in a sealed container at room temp up to a week. If needed, freeze them for longer.
