Oooops, I made these again... Jessica's super chocolate cookies

I must be going crazy. Or senile.

Valentina posted a cookie recipe on her blog in Portuguese especially for my sister. They looked super tasty and Jessica and I baked them in one of the days she spent at my house.

I was completely surprised to realize, more than a month later, when I was about to post the cookies, that I had already baked them…

I didn’t notice it. Not even for a moment. They looked a bit different, too – and I’m not trying to justify myself here. :)

These cookies are so delicious they are worth being posted again – it was a good thing that Jessica had the idea of using white chocolate chips, too, so they (sort of) have a new look. :)

Super chocolate cookies with dark and white chocolate chips

125g dark chocolate, minimum 70% cocoa – I used 60%
150g flour
30g cocoa powder
1 generous teaspoon baking soda
½ teaspoon salt
125g unsalted butter, room temperature
75g brown sugar
50g caster (superfine) sugar
1 teaspoon vanilla extract
1 large cold egg
100g semisweet chocolate chips
100g white chocolate chips

Position a rack in the middle of the oven. Preheat the oven to 165ºC/325ºF.
Line 2 baking sheets with parchment paper.

Put the dark chocolate in a heatproof container or the top of a double boiler and place it over, but not touching, a saucepan of barely simmering water (or the bottom of the double boiler). Stir the chocolate until melted and smooth. Remove from the water and set aside.

Sift the flour, cocoa powder, baking soda and salt into a medium bowl and set aside. In a large bowl, using an electric mixer on medium speed beat the butter, brown sugar and sugar until smoothly blended, about 1 minute.
Stop the mixer and scrape the sides of the bowl as needed during mixing. On low speed, mix in the melted chocolate until blended. Add the egg and vanilla, mixing until blended, about 1 minute. Add the flour mixture, mixing just until it is incorporated. Mix in the chocolate chips (both semisweet and white).

Using an ice cream scoop or measuring cup with a ¼-cup capacity*, scoop mounds of dough onto the prepared baking sheets, spacing the cookies 3 inches apart.

Bake the cookies one sheet at a time until they crack slightly on top and a toothpick inserted in the center of a cookie comes out with moist crumbs, not wet batter, about 18 minutes (if the toothpick penetrates a chocolate chip, test another spot).
Cool the cookies on the baking sheet for 5 minutes, then use a wide metal spatula to transfer them to a wire rack to cool completely. The outsides of the cookies will become crisp as the cookies cool.

The cookies can be stored in a tightly covered container at room temperature for up to 4 days.
