Followed this Serious Eats recipe. It was amazing. I never want to eat a “real” Twix bar again. Now just to figure out how to make Butterfingers…

The base shortbread was fantastic — no need for caramel or chocolate.

Adapted from the Serious Eats page above:

2.5 ounces (1/2 cup) steel-cut oats
7.5 ounces (1 1/2 cups) all-purpose flour (I subbed for a half cup of whole wheat, just because I want to use it up)
1.5 ounces (1/4 cup) cornstarch
3 ounces (2/3 cup) confectioner’s sugar
1/2 teaspoon salt
14 tablespoons unsalted butter, cut into halfinch-ish chunks

Dump all the dry ingredients into a food processor, then add the butter. Process until a dough forms. Then roll it out into cookies! Bake at 450F for ten minutes, then 300F for another 15 minutes, rotating halfway.

I made both cookies as detailed in the link above, and a tray of Twix. Half a recipe of the dough filled an 8×8 pan. I had a hard time getting an evenly thin layer of chocolate in the tray though.

Would (will) make again! Maybe just the cookies.
