This is an ideal pastry to prepare in advance for the Christmas festivities.

Set the oven rack in the center of the oven. Preheat at 325°F (160°C).
In a large bowl, using a whisk, beat the eggs, brown sugar and vanilla until combined. Add the nuts. Reserve.

In a large bowl or in a food processor, combine butter and cheese until smooth. Using a wooden spoon or in a food processor, mix in the flour.
On a lightly floured surface, roll out a third of the dough to ¼ inch(6 mm ) and cut into 24 circles of 2 ½ in (6 cm) diameter. Line the 24-cavity miniature muffin molds with the pastry circles. Fill the molds 2/3 full with the walnut mixture; stir the mixture from time to time to evenly distribute the nuts. Bake for 25 to 30 minutes Cool for 1 minute, remove with a butter knife and cool on a rack.

Repeat the previous step with the other two pieces of dough.
