- 2 cups salted butter, cold and cut into pieces
- 1 cup packed light brown sugar
- 4½ cups all purpose flour, divided
- Jar of Nutella (I use the smaller jar)
- Optional: Your favorite sprinkles
- In the bowl of a stand mixer, add butter and brown sugar. Using paddle attachment on medium-high speed, mix until fluffy and light, several minutes. Add 3½ cups of the flour and mix on medium-low speed until combined.
- On a large board, sprinkle ½ cup flour. Knead dough by hand for 5 minutes, adding as much of the remaining ½ cup flour as needed to make a soft dough. The dough should end up soft and pliable, similar to play-dough, not sticky. (You may not end up using all the flour, depending on how your dough feels.) Divide dough in half, wrap tightly, and chill for at least 30 minutes or until firm enough to roll.
- Meanwhile, preheat oven to 325F, with rack on lower middle position. Line baking sheets with parchment paper or silicone mats; set aside. Place enough Nutella in a sandwich-size Ziploc bag to fill it about halfway. Carefully snip a tiny bit off the corner, making a piping bag. Set aside.
- Working in 2 batches, form dough balls with the chilled dough, about 1-inch each. Form a deep well in the center using the back of a wooden spoon or index finger (you want it deep, but not too wide.) Place 2 inches apart on lined baking sheet and bake 8-10 minutes (these won’t brown on top much, but the bottoms should be golden brown.) If needed, very gently depress the centers of baked cookies again. Fill centers to the brim with Nutella, using your Ziploc piping bag. Top with sprinkles, and return to oven for another 3 minutes. Let cool completely on baking sheet. Cookies keep well when sealed airtight, at room temp.
Don’t worry about the center well seeming not wide enough – they will spread out a bit after baking and after the Nutella is piped in. You can also widen the center well a bit right before piping in the Nutella. I’ve found that the back of my wooden spoon works very well for a deep center well.
Unused dough can be wrapped airtight and stored in freezer up to a month.
