Instructions

  • 5. Gradually combine the dry ingredients with the wet ingredients.
  • 6. Fold in the sour cream and chocolate chips.
  • 7. Spread the batter evenly into the prepared pan.
  • 8. Bake for 22–28 minutes until the edges are set and the center is slightly soft.
  • 9. Cool the bars completely before frosting.
  • 10. Prepare the frosting by beating butter, powdered sugar, cocoa powder, heavy cream, vanilla extract, and salt until smooth.
  • 11. Spread frosting evenly over the cooled bars.

Notes

Use room-temperature butter and eggs for a smoother batter and softer texture.
Do not overbake the bars; the center should remain slightly soft for a fudgy consistency.
Chill the frosted bars for 20 minutes before slicing to achieve cleaner cuts.
