To keep this recipe from being overly long, I’ve directed you to my previous kolache recipe for the dough and posypka and only included instructions for the strawberry and cream cheese fillings. Please make the dough as directed and be sure and have the melted butter on hand for brushing when the kolaches come out of the oven.
To make the strawberry filling, place the sliced strawberries, sugar, and lemon juice in a pot and allow them to sit with the burner off for 30 minutes or until the strawberries begin to release some of their juices. After they’ve released some juices, turn the heat to medium high and while occasionally stirring, cook the strawberries until thick and jammy, about 10-12 minutes. Turn off the heat, stir in the cinnamon, and mash the berries with the back of your spoon or a masher. Allow to cool and then refrigerate until needed. (The cooler the strawberry filling is, the less likely it will run as it bakes, says this cook from experience. I’d make this when the dough is doing its first rising or even the night before.)
To make the cream cheese filling, beat the cream cheese and sugar together until fluffy. Stir in the flour, egg yolk, vanilla, and lemon zest until smooth. Refrigerate until ready to use.
After the kolache dough has done the first rising, form it as directed on 2 parchment paper lined baking sheets, cover, and allow it to rise for 30 more minutes.
After this time, preheat the oven to 375°F. Uncover the rising dough and with the back of a spoon or your thumb, gently form a well in the center of each roll. Fill the well with 1 teaspoon of the strawberry filling and then top that with 1 teaspoon of the cream cheese filling. After filling the kolaches, sprinkle the posypka generously over all of them.
Bake for 12-15 minutes, or until the rolls are golden brown. While baking, melt the remaining 4 tablespoons of butter that’s listed in the kolache dough recipe. When you take the kolaches out of the oven, brush with the melted butter and serve warm.
