Chef Emma’s Helpful Tips

To ensure your brownies turn out perfect every time, keep these kitchen secrets in mind:

  • Perfectly Cut Brownies: For cleaner cuts, use a plastic knife or a hot knife (run it under hot water first) to slice through the fudgy texture.
  • Make Ahead: Bake a batch ahead of time and store them in an airtight container. They stay fresh for a few days, making them a wonderful make-ahead treat.
  • Storage Suggestions: If you have leftovers, store your brownies in the fridge to prolong their freshness—they’re just as tasty chilled!
  • Ingredient Swaps: Want to make these brownies gluten-free? Substitute the all-purpose flour with a 1:1 gluten-free baking mix.
