How To Make Rugelach

Makes 64 cookies

What You Need

Ingredients 
2 cups all-purpose flour
1/4 teaspoon fine salt
8 ounces cold cream cheese, cubed
2 sticks (1 cup) cold unsalted butter, cubed
1 teaspoon vanilla extract
1 large egg yolk
1 batch filling (see ideas below)
Powdered sugar

Equipment
Food processor
Rolling pin
Pizza cutter or sharp knife
2 baking sheets
Parchment or silicone baking mats

Instructions

1. Combine the flour and salt. Combine the flour and salt in the bowl of a food processor fitted with the blade attachment. Pulse several times to mix.
2. Mix in the cream cheese and butter. Scatter the cubes of cream cheese and butter over the flour. Pulse until coarse crumbs form, 10 to 12 pulses.
3. Mix in the yolk and vanilla. Whisk the vanilla and yolk together in a small bowl. Drizzle over the butter-flour mixture. Process until the dough starts to clump together and form large, curd-like pieces.
4. Refrigerate the dough. Transfer the dough out onto the counter and gather the pieces into a ball. Divide into 4 portions and flatten each into 1-inch-thick disks. Wrap each disk in plastic wrap and refrigerate at least 2 hours or up to 3 days, or freeze for up to 3 months (thaw in the refrigerator before using).
5. When ready to bake the rugelach, preheat the oven to 375°F. Arrange a rack in the middle of the oven and heat to 375°F.Line 2 baking sheets with parchment paper. Meanwhile, prepare the fillings.
6. Roll out the dough. Sprinkle your work surface generously with powdered sugar. Take 1 disk of dough from the refrigerator and let it warm on the counter for 1 to 2 minutes. Unwrap and then sprinkle the surface of the dough and the rolling pin with more powdered sugar. Roll the dough from the center out into a circle about 1/8-inch thick. Don't worry if a few cracks form near the edges. Use more powdered sugar as needed to prevent sticking.
7. Spread with filling. Spread the filling in a thin layer evenly over the surface of the dough. Make sure it goes right up to the edge of the dough.
8. Cut and roll the cookies. Using a pizza cutter or sharp knife, cut the dough into 16 wedges, like a pizza. Beginning at the wide outer edge and moving inward, roll up each wedge. Transfer to a parchment-lined baking sheet. Make sure the tip is tucked underneath.
9. Chill the cookies. Refrigerate cookies on the baking sheet, 20 minutes. Meanwhile, prepare remaining batches.
10. Bake the cookies. Bake the first tray of cookies until golden-brown, 20 to 25 minutes. Cool on the sheet, 5 minutes; transfer to a wire rack. Bake the remaining cookies, using the same parchment paper but making sure the baking sheet is cooled between batches.

Ideas for Rugelach Fillings

• Nut filling: In a food processor, pulse 1 cup walnuts and 1 cup pecans until they break into tiny crumbs, 30 to 40 pulses. (Be careful of over-processing and making nut butter.) Combine the ground nuts in a bowl with 4 tablespoons (1/4 cup) melted butter, 1/4 cup honey, 1/4 cup granulated sugar, and 1 teaspoon vanilla extract.
• Fruit and jam filling: Warm 1/4 cup marmalade, apricot jam, or raspberry jam in the microwave until it liquefies. Stir in 1 tablespoon sugar. Set aside to cool until no longer steaming, still liquidy. Pulse 2 cups (roughly 10 ounces) dried fruit, such as apricots, cranberries, cherries, or currants, in a food processor until it breaks down into tiny pieces. To assemble, spread the jam onto the rugelach dough and then sprinkle the dried fruit on top.
• Peanut butter and chocolate filling: Warm 1/2 cup peanut butter in a microwave until it liquefies but isn't boiling. Spread over the rugelach dough; sprinkle with 1 cup miniature chocolate chips.

Recipe Notes

• Freezing rugelach: The disks of dough can be frozen for up to 3 months; thaw in the refrigerator overnight before using. The shaped cookies can also be frozen for up to 3 months. Arrange cookies on a baking sheet, making sure they do not touch, and freeze until solid. Transfer to a freezer container for long-term storage. Cookies can be baked straight from the freezer and may need an extra few minutes to bake.
• Making rugelach by hand: If you don't have a food processor, just cut the cream cheese and the butter into the flour mixture using your fingertips or a pastry cutter, just as you would for pie crust. Sprinkle the yolk mixture over the top and fluff the dough with your fingers until it feels heavy and can hold together when pressed into a ball. Proceed with the rest of the recipe as instructed.
• Halving this recipe: Nix the egg yolk and cut the rest of the ingredients in half.
• Storage: Cookies will keep in an airtight container at room temperature for about a week.
