Notes

Tips to Make the Best Healthy Almond Croissant Bars
 
  1. Sprinkle water over the sliced almonds, before adding them on top of the bars, lightly sprinkle them with water. This helps prevent burning during baking and keeps them golden and crisp instead of overly darkened.
  2. Use room temperature ingredients, for the best texture, make sure your eggs, almond milk, and other refrigerated ingredients are at room temperature. This helps them blend more smoothly and creates a more even, tender texture.
  3. Beat egg whites to firm peaks, when beating the egg whites, make sure they reach firm peaks before folding them into the batter. This gives the bars a light, airy structure that balances the rich almond flavour.
  4. Fold gently, when adding the egg whites to the batter, fold gently to keep the mixture airy. Overmixing can deflate the batter and result in a denser texture.
  5. Use softened butter or coconut oil, if using butter for the almond frangipane layer, make sure it’s softened (not melted) to ensure smooth mixing. For a dairy-free or Paleo version, use softened coconut oil instead.
  6. Cool completely before slicing, let the bars cool fully before removing them from the pan and slicing. This allows the layers to set properly and helps you get clean, even slices without crumbling.
  7. Dust just before serving, for a pretty finish, dust the top with monk fruit icing powder or your preferred powdered sweetener right before serving. This keeps the bars looking fresh and inviting.
