Kolaches

In a small bowl, combine warmed 180ml whole milk (heated to exactly 43°C/110°F, no hotter to avoid killing yeast), 1 teaspoon of the measured granulated sugar, and the 7g packet of active dry yeast. Stir gently once to combine, then let rest for 5-7 minutes in a warm, draft-free spot until the mixture forms a foamy, bubbly layer and smells distinctly of bready yeast. If no foam forms after 7 minutes, your yeast is expired and you will need to replace it before proceeding.

In the bowl of a stand mixer fitted with a dough hook attachment, combine 480g of the all-purpose flour, remaining granulated sugar (minus 2 tablespoons reserved for streusel), 5g fine salt, cooled melted 57g unsalted butter, lightly beaten room-temperature eggs, and the fully activated yeast mixture. Mix on low speed (setting 2 on most household stand mixers) for 8 full minutes, until the dough pulls cleanly away from the bowl sides and forms a smooth, soft, slightly tacky ball. If mixing by hand, turn the shaggy dough onto a lightly floured work surface and knead for 12-14 minutes until the same smooth, elastic texture is achieved.

Grease a large clean mixing bowl with 1 teaspoon of neutral canola oil, place the kneaded dough ball inside, and turn it once to coat its entire surface lightly in oil to prevent drying. Cover the bowl tightly with plastic wrap or a damp linen kitchen towel, and set it in a warm (24-27°C/75-80°F), draft-free spot for 60 minutes, until the dough has fully doubled in size. Test for doneness by poking the dough with a floured finger: the indent should slowly rebound halfway, not spring back immediately or deflate completely.

While the dough completes its first rise, prepare the fillings and crumb topping. Make the cream cheese filling by beating softened 113g block cream cheese, 15g powdered sugar, 1/2 teaspoon lemon zest, and 2.5ml vanilla extract in a small bowl with a spoon or hand mixer until completely smooth, with no visible lumps. Make the traditional posipka streusel topping by combining the remaining 20g all-purpose flour, 2 tablespoons reserved granulated sugar, and 14g cold cubed unsalted butter in a small bowl, pinching with your fingertips until the mixture forms coarse, pea-sized buttery crumbs. Scoop the 120g thick apricot preserves into a third small bowl for easy filling.

Once the dough has doubled, punch it firmly in the center to release all trapped air, then turn it out onto a lightly floured work surface. Divide the dough into 12 equal 70g pieces, rolling each piece into a tight, smooth ball by tucking the edges under. Place the dough balls 5cm (2 inches) apart on two parchment paper-lined baking sheets, then cover loosely with oiled plastic wrap and let rest for 15 minutes to relax the gluten. After resting, use the floured bottom of a 1/4-cup dry measuring cup to press a deep, wide indentation in the center of each dough ball, leaving a 1cm (1/2 inch) raised dough border around the edge. Fill half the indentations with 1 tablespoon (approx 20g) of cream cheese filling, and half with 1 tablespoon (approx 20g) of apricot preserves, then sprinkle 1 teaspoon of streusel topping evenly over each filled kolache.

Cover the filled kolaches loosely with oiled plastic wrap again, and let them rise for 25-30 minutes in the same warm, draft-free spot, until the dough borders look puffy and jiggle slightly when the baking sheet is gently shaken. While the kolaches rise, preheat your oven to 190°C (375°F) with racks positioned in the upper and lower thirds. Once risen, remove the plastic wrap and bake the kolaches for 12-15 minutes, rotating the baking sheets from top to bottom and front to back at the 7-minute mark, until the pastry edges are light golden brown and the fillings are just set. Avoid overbaking, as this will result in dry, tough dough.

Remove the baked kolaches from the oven, and immediately brush the warm dough borders with the remaining 29g melted unsalted butter to create a soft, glossy finish and keep the crust tender. Let the kolaches rest on the hot baking sheets for 10 minutes to set, then transfer them to a wire cooling rack to cool for an additional 10 minutes before serving. Kolaches are best enjoyed warm, on the same day they are baked.
