Activate the yeast. Combine warm water, yeast, and 1 teaspoon of sugar in a small bowl. Stir and let sit for 10 minutes, until the yeast is foamy and active.
Mix the dough. In a large bowl, mix together the sugar, milk, melted shortening or butter, salt, and egg yolk. Stir in the yeast mixture. Add the sifted bread flour 1 cup at a time until 3 cups are incorporated, stirring until a sticky dough starts to form.
Knead. Sprinkle the remaining ⅓ cup bread flour onto a hard work surface. Turn the dough out and knead for 10-12 minutes, until smooth and elastic. The finished dough should be soft and slightly sticky.
Let rise. Transfer the dough to a lightly greased bowl and cover. Let rise for 1 hour until puffy and nearly doubled in size.
Shaping and Filling Dough
Punch dough down. Roll into a log and cut into 12 equal size pieces, approximately the size of golf balls (2 oz. each). Place dough ball in a lightly greased half sheet pan (13” x 18”) and brush with 1 tbsp. of melted butter. Cover and let rise for 30 minutes.
Make wells in the center by pressing a lightly floured ¼ c. measuring cup into the center of each dough ball. Fill each dough ball with 1 Tbsp. of cream cheese filling. Brush sides with more melted butter. Cover and let rise for ~ 30 minutes-1 hour.
After dough has risen, spoon 1-2 tsp. of fruit filling into center of cream cheese filling. Sprinkle with streusel topping.
Bake at 350°F for 25-30 minutes or until golden brown.
Cream Cheese Filling
In a high speed mixer, whisk together cream cheese, sugar, egg yolk and vanilla extract for 1-2 minutes or until creamy.
Streusel Topping
In a medium bowl, combine flour, sugar, salt, cinnamon. Cut butter into dry mixture until coase crumbles form.
Notes
*Milk should not be cold, either room temperature or slightly warm. Lemon Cream Cheese: Add lemon juice or zest to the cream cheese filling for a lemon cream cheese filling.Stand Mixer MethodIf you prefer to use a stand mixer, follow these adjusted steps to keep the dough from becoming too soft or greasy:
Step 1: In the mixer bowl, combine the activated yeast mixture, sugar, milk, salt, egg yolk, and 3 cups of the sifted bread flour. Mix with the paddle attachment on low until a shaggy dough forms.
Step 2: With the mixer on low, slowly stream in your lukewarm melted butter or shortening. Mix for 60 seconds until completely absorbed.
Step 3: Switch to the dough hook and turn the mixer to speed 2. Gradually add the remaining ⅓ cup of bread flour one tablespoon at a time.
Step 4: Knead on speed 2 for 6–8 minutes until the dough looks smooth, elastic, and cleanly clears the sides of the bowl. Proceed to the first rise as directed.
