CRUCIAL TIPS
  • Don’t overfill the waffle maker – it’ll overflow.
  • Let chaffles cool for 1 minute to achieve maximum crispiness.
  • Use pre-shredded cheese for convenience, but freshly grated gives better melt.
STORAGE
  • Chaffles keep 3 days refrigerated.
  • Reheat in toaster for best results.
  • Don’t pre-assemble – make fresh.
COMMON MISTAKES
  • Opening waffle maker too soon (wait for steam to reduce).
  • Using too much almond flour (makes them cakey).
  • Skipping the baking powder (reduces fluffiness).
VARIATIONS
  • Sausage patty instead of bacon.
  • Add sliced avocado.
  • Use different cheese varieties in chaffle batter.
  • Spice it up with everything bagel seasoning.
