07 - Add dry ingredients to butter mixture in three additions, alternating with the soda and sour cream mixture, beginning and ending with dry ingredients. Mix until just combined.
08 - Gently fold rainbow sprinkles into batter.
09 - Spread batter evenly into prepared pan. Sprinkle cinnamon streusel over the top.
