Notes

*This recipe was written using an average of the dip and sweep method for measuring flour and the spoon and level method. If you are using a scale, you will need to add 3/4 oz or 22 g  to the measurement for each cup of flour.
Substitutions:
  • Semi-sweet can be used in place of bittersweet chocolate.
  • To make this recipe dairy-free, you can use a dairy-free chocolate and your favorite plant-based butter.
Expert Tips:
  • If you're worried the brownies may stick, place an 8 inch square piece of parchment in the bottom of your pan. Then, spray with baking spray!
  • Be careful to not over-mix the brownie batter!
  • These brownies are very fudgy. If you like them a little more done, leave in an additional 5 minutes.
  • To get the ganache to set faster, place the brownies in the fridge for 10-15 minutes!
