Red Velvet Cinnamon Rolls

Red Velvet Cinnamon Rolls
Recipe from Taste of Home 2021
1 package red velvet cake mix (regular size)
2-1/2 to 3 cups all-purpose flour
1 package (1/4 ounce) active dry yeast
1-1/4 cups warm water (110° to 115°)
1/2 cup packed with brown sugar
1 teaspoon ground cinnamon
1/4 cup of butter, melted
ICING:
2 cups of confectioners' sugar
2 tablespoons butter, softened
1 teaspoon vanilla extract
3 to 5 tablespoons 2% milk
Combine cake mix, 1 cup flour and yeast. Add water; beat at a medium speed for 2 minutes. Stir in enough remaining flour to form a soft dough (dough will be sticky). Turn onto a lightly floured surface; knead gently 6-8 times. Place it in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until doubled, about 2 hours. Meanwhile, in another bowl, mix brown sugar and cinnamon.
Punch down dough. Turn onto a lightly floured surface; roll dough into an 18x10-in. rectangle. Brush with melted butter to within 1/4 in. of edges; sprinkle with sugar mixture.
Roll up jelly-roll style, starting with a long side; pinch seam to seal. Cut crosswise into 12 slices. Place cut sides up in a greased 13x9-in. baking pan. Cover with a kitchen towel; let rise in a warm place until it is almost doubled, about 1 hour.
Preheat oven to 350°. Bake until puffed and light brown, 15-20 minutes. Cool slightly.
Beat confectioners’ sugar, butter, vanilla and enough milk to reach a drizzling consistency. Drizzle icing over warm rolls.
