Notes

TIPS & NOTES:
  • Use thick Greek yogurt for the creamiest texture and best layers.
  • Let the berry mixture cool slightly before layering over the yogurt.
  • Adjust the honey to suit your preferred sweetness level.
  • Refrigerate overnight for the best texture and flavor.
  • Add the chopped peanuts just before serving to keep them crunchy.
  • Swap peanut butter for almond or cashew butter if preferred.
  • Stir vanilla protein powder into the yoghurt layer for an extra protein boost.
  • Fresh or frozen berries both work well in this recipe.
  • Make multiple portions ahead for an easy grab-and-go breakfast.
  • Add extra peanut butter or a drizzle of honey on top before serving for an indulgent finish.
 
MEASUREMENTS:
I always recommend using a kitchen weighing scale and using weighted measurements. This will result in a more accurate process and your overnight weet-bix will come out perfectly.
