๐Ÿงพ Ingredients

Dry Ingredients

  • 1 ยฝ cups oat flour
    (or blend rolled oats into flour)

  • ยฝ tsp baking soda
  • ยฝ tsp salt
  • 1 tsp cinnamon (optional but recommended)

  • 2 large eggs
  • ยพ cup plain Greek yogurt (0โ€“5% fat)
  • โ…“ cup honey or maple syrup
  • ยผ cup milk (any kind)
  • ยผ cup melted coconut oil or olive oil
  • 1 tsp vanilla extract

Add-Ins

  • 1 cup fresh or frozen blueberries
  • 1 tsp flour or oat flour (to toss blueberries)

๐Ÿ‘ฉโ€๐Ÿณ Instructions

  1. Preheat oven to 350ยฐF (175ยฐC).
    Grease or line a 9ร—5-inch loaf pan with parchment paper.
  2. Mix dry ingredients
    In a large bowl, whisk together oat flour, protein powder, baking powder, baking soda, salt, and cinnamon.
  3. Mix wet ingredients
    In a separate bowl, whisk eggs, Greek yogurt, honey/maple syrup, milk, oil, and vanilla until smooth.
  4. Combine
    Add wet ingredients to dry ingredients. Gently mix until just combined.
    Do not overmixโ€”protein powder can make bread dense if overworked.
  5. Prepare blueberries
    Toss blueberries with 1 tsp flour (prevents sinking).
    Fold gently into the batter.
  6. Bake
    Pour batter into loaf pan and smooth the top.
    Bake for 45โ€“55 minutes, covering loosely with foil at 35 minutes if the top browns too quickly.
  7. Cool
    Let cool in the pan for 15 minutes, then transfer to a wire rack.
    Slice once fully cooled for best texture.
