Vegan substitution

For a vegan twist, you can swap out the eggs with flax eggs. To make flax eggs, simply mix 1 tablespoon of ground flaxseed meal with 2.5 tablespoons of water. Let the mixture sit for a few minutes until it thickens, and then use it as a replacement for each egg in the recipe.

Food safe storage

Keep your squares fresh and fabulous by storing them in an airtight container in the fridge. And if you want to prevent any stickiness, just pop a bit of parchment paper between each square—easy peasy! This method ensures they stay delicious and easily accessible for up to three days.

  • Vegan Option: For a vegan twist, swap out eggs with flax eggs—it’s a simple yet effective alteration.
  • Fruit Variations: Experiment with different fruits like strawberries, apricots, or rhubarb to add diverse flavours to your squares.
  • Chocolate Indulgence: Elevate the richness by tossing in a handful of dark chocolate chips or cacao nibs for that extra depth.
  • Individual Portions: Use a muffin pan to create individual baked oatmeal cups, perfect for easy grab-and-go breakfasts.
  • Spice It Up: Garnish your squares with spices like ginger powder or pumpkin pie spice to impart a flavorful kick.
  • Tantalizing Toppings: Let your creativity soar! Consider toppings like chopped almonds, pecans, shredded coconut, chia/hemp seeds, or chocolate chips for added texture and flavour.
  • Mug-Friendly Variation: Simplify with a mug version! Pour half the mixture into a microwave-safe mug and cook for 2-4 minutes on high power for a quick individual serving.
