Tips for making the brownies

Here are my tips, so yours turns out like this recipe!

  • Tip 1: When you are baking the brownies, you need to be careful when you stir in the rest of the ingredients after the eggs are beaten. If they are added in too fast, the eggs’ air will deflate and you won’t get as much of a rise from the brownies.
  • Tip 2: Make sure to spray the pan with baking non-stick spray, so the brownies don’t stick to the pan. It is also a good idea to place parchment paper on the bottom of the tray as well. Make sure your parchment paper comes far enough up the sides that you can use it as a handle to lift the brownie to make removing it from the tray easier.
  • Tip 3: When beating the eggs and sugar together, you should be able to rub the batter between your fingers and not feel any sugar granules. This helps give it is crinkle top.
