An Evie's Kitchen original...
2 c bread flour
1 tsp baking soda
1 tsp salt
1/2 c cocoa powder
2 sticks melted butter
1/2 c granulated sugar
1 c light brown sugar
1 egg + 1 yolk
2 Tbsp milk
1 tsp vanilla extract
2 tsp instant coffee
8 oz bittersweet chocolate (I recommend 2 x 4 oz bars of Ghirardelli 60% cacao)
4 oz semisweet chocolate (again, a 4 oz bar of Ghirardelli)
Finely chop 4 oz bittersweet and 4 oz semisweet chocolate as shown. Set aside.
Break remaining 4 oz bar of bittersweet chocolate into about 20 pieces. This will be used as molten chocolate centers later.
Whisk together flour, baking soda, salt and cocoa powder. Set aside.
Cream butter and sugars in a standing mixer. Add egg, yolk, vanilla, milk and instant coffee. Slowly add dry ingredients. Add the 8 oz finely chopped bittersweet and semisweet chocolate.
Refrigerate dough for at least 20 mins to chill. Meanwhile preheat oven to 350 and line 2 baking sheets with parchment paper.
Remove dough from refrigerator, scoop out 8-10 cookies on each sheet. Flatten gently and place a small square of chocolate in the middle as shown:
Then place another flattened dough ball on top of that, press gently so they stick together:
Press each cookie in a small dish of granulated sugar if desired to coat the cookie tops. Bake at 350 for 12-15 mins until tops look dry and slightly cracked.
Serve warm, or allow to cool and store in tupper ware at room temp, but microwave at medium power for 20 seconds before eating to enjoy the molten centers!
