SWEET SOUR CREAM FILLING RECIPES

Steps:

• Dissolve 1 tbsp sugar in the warm water in a small bowl. Sprinkle the yeast over the water. Do not stir. Cover and let stand for 5 minutes. Stir briefly with a fork, cover and let stand for 2 to 3 minutes or until bubbly.
• In the bowl of an electric mixer fitted with the paddle attachment, mix the 3 cups of flour, remaining 3 tablespoons of sugar, and the salt. Add the slightly firm butter and continue to mix until meal-size crumbs form, about 2 to 4 minutes depending upon the temperature of the butter.
• Mix together the eggs, sour cream, and vanilla in a separate bowl. Add the sour cream mixture to the flour along with the dissolved yeast, and mix on low until a rough dough is formed. Dough will be soft and sticky. You may need to add a little flour to make it handle-able but add as little as possible or else the dough will become tough.
• Lightly butter a medium bowl. Turn the dough into the prepared bowl, smoothing the top with lightly floured hands. Brush the top lightly with a small amount of softened butter. Cover and let rise for 45-60 minutes at room temperature. ***For later use: cover with plastic wrap and refrigerate for up to 3 days. When ready to use, let it come to room temperature and finish rising.
