Make the Strawberry Filling:

In a saucepan, heat 15 oz frozen strawberries over low heat until softened, about 5 minutes. Add 1/4 cup sugar and mix. Use a fork to crush the strawberries. Dissolve 2 tablespoons cornstarch in 2 tablespoons water, then add to the strawberry mixture along with 1 tablespoon vanilla extract. Bring to a low boil and cook for 5-6 minutes until thickened. Remove from heat and cool. Reserve 2 tablespoons of filling for the icing.

Prepare the Dough:

In the bowl of a stand mixer, combine 3/4 cup warm kefir, 1/4 cup sugar, 1 tablespoon yeast, and 1/4 cup melted butter. Stir and let sit for 10 minutes. Add 2 eggs, 3 cups bread flour, and 1 teaspoon salt. Beat on medium speed using a dough hook for about 8 minutes until a soft dough forms. If the dough sticks to the bowl, add up to 3 tablespoons of flour as needed.

First Rise:

Grease the mixing bowl and place the dough inside. Cover and let rise in a warm place for about 1 hour, or until doubled in size.

Prepare the Baking Pan:

Grease a 9x13-inch baking pan with butter or cooking spray, or line it with parchment paper.

Roll Out the Dough:

On a lightly floured surface, roll out the dough into a rectangle, about 12 inches wide by 16-18 inches long.

Fill and Roll the Dough:

Spread 3/4 cup of the strawberry filling over the dough, leaving a small border. Sprinkle 2 teaspoons of cinnamon over the filling. Roll the dough tightly from the long side into a log. Using dental floss or clean thread, cut into 12 equal pieces. Place in the prepared baking pan.

Second Rise:

Cover and let rise in a warm spot for 30-45 minutes until doubled in size.

Bake the Rolls:

Preheat the oven to 350°F (175°C). Bake the rolls for 18-25 minutes, until the edges are lightly brown and the internal temperature reaches 190°F.

Prepare the Icing:

Beat 2 tablespoons butter and 1/4 cup cream cheese together until smooth, about 1 minute. Add 1 1/2 cups confectioners' sugar and mix on low until combined. Add the reserved 2 tablespoons of strawberry filling and beat on medium until fully mixed.

Ice the Rolls:

Spread the strawberry cream cheese icing over the warm rolls. Garnish with fresh or freeze-dried strawberries, if desired.

Serve and Enjoy!

Serve the rolls warm and enjoy the fruity, sweet flavors with family and friends.
