Preheat your oven to 350°F (175°C). This ensures your granola cooks evenly and gets that perfect crunch.
In a large mixing bowl, combine the oats, chopped almonds, chia seeds, flax seeds, and a pinch of salt. Stir well to ensure all the dry ingredients are evenly mixed.
In a separate bowl, whisk together the vanilla extract, egg whites, honey, and oil until well blended. This mixture will help bind the granola together.
Pour the wet mixture over the dry ingredients. Stir until all the oats and seeds are coated with the wet ingredients. This will help the granola clump together during baking.
Spread the granola mixture evenly onto a baking sheet lined with parchment paper. Bake in the preheated oven for 20-25 minutes, stirring occasionally, until golden brown. Keep an eye on it to prevent burning!
Once baked, remove the granola from the oven and let it cool completely on the baking sheet. It will harden as it cools, creating those delightful crunchy clusters.
In a glass jar or cup, layer the Greek yogurt, followed by a generous scoop of granola. Top with your favorite berries, a sprinkle of nuts or seeds, and a drizzle of honey if desired. Repeat the layering until your cup is filled, then enjoy!
