Recipe Notes

How to make Sriracha Brownies from a box mix?

  • Prepare the batter your favorite box mix per package directions. 
  • Only use 2 eggs for chewier brownies instead of the cake-like 3 egg method. 
  • Stir in the Sriracha to the prepared batter.
  • Bake per package directions.

Suggestions for making brownies from a box mix even better.

  • Grate 2-3 tbsp of your favorite dark or milk chocolate bar into the batter for increased chocolate flavor. 
  • Use 1 tsp instant coffee mixed into the water when making the batter or use warm (not hot or cold) coffee in place of the water.
