These tender, protein-packed muffins are a family favorite, known as purple dot muffins. They are a nutritious, grab-and-go breakfast or snack made with simple ingredients like Greek yogurt and whole wheat flour.
For frozen blueberries, do not thaw; toss in flour first to prevent sinking. Muffins freeze well for up to 3 months. Protein powder can be whey or plant-based; if omitted, replace with an equal amount of oat flour.
