Blobbs

Steps

1. Line two baking sheets with parchment paper.

2. Place the butter in a medium microwave-safe bowl and heat in the microwave until melted, about 1 minute. Add the chopped chocolate and stir to combine. Heat the melted butter and chocolate in the microwave for 20-second intervals, stirring between each bout of heat, until almost melted. Stir, allowing the residual heat in the bowl to melt the chocolate completely. (Alternatively, the butter and chocolate can be melted together slowly in a double boiler on the stovetop.) Set aside and cool to room temperature.

3. In a small bowl, whisk together the flour, baking powder, and salt. Set aside.

4. In the bowl of a stand mixer fitted with the whisk attachment (or a hand mixer), beat the eggs on medium speed until light, creamy, and foamy, about 90 seconds.

5. Add the sugar and continue whipping on medium speed until very light and creamy, about 90 seconds more. Add the vanilla and beat again quickly to combine.

6. Change the whisk attachment to the paddle attachment on the mixer (if using a hand mixer, leave the beaters). Gradually add the melted chocolate mixture, mixing on medium speed to combine.

7. Add the flour mixture and mix on low speed until incorporated, scraping the sides and bottom of the bowl as necessary.

8. Add the chocolate chips and nuts and mix in on low speed. Finish by hand to be sure it's all evenly combined, especially at the bottom.

9. Use a 2-inch (5-cm) ice cream scoop to scoop the batter, packing the mixture in and scraping off any excess. Place the mounds of batter onto the prepared baking sheets about 2 inches (5 cm) apart. Refrigerate for at least 30 minutes. (Leave the remaining batter at room temperature on the countertop or scoop and chill on a separate lined baking sheet.)

10. Position the racks in the upper and lower thirds of the oven, and preheat the oven to 350°F (175°C).

11. Bake the chilled blobbs for 15 to 17 minutes, rotating the pans from top to bottom and front to back half through the baking time. Let cool on the baking sheet for a few minutes, then use a spatula to transfer to a cooling rack. Repeat with the remaining batter, or freeze the unbaked blobbs and bake them frozen another time.
