Directions

  1. Preheat the oven to 350°F (180°C). Grease a loaf pan and line it with parchment paper for easy removal.
  2. In a medium bowl, whisk together 1 1/3 cups all-purpose flour, one scoop vegan vanilla protein powder, 1/2 tsp baking soda, 1 tsp baking powder, and 1/2 tsp sea salt.
  3. In a separate large bowl, combine 3/4 cup granulated monk fruit sweetener (or sugar) and 1 tablespoon fresh lemon zest. Rub the zest into the sweetener with your fingers to release the lemon oils and intensify the flavor.
  4. Add 1/4 cup melted coconut oil, 1/4 cup fresh lemon juice, 3/4 cup almond milk, 1/2 cup dairy-free Greek-style yogurt, and 1 tsp vanilla extract to the sweetener and zest. Whisk until well combined.
  5. Fold the dry ingredients into the wet mixture gently until just combined—do not overmix to keep the loaf tender.
  6. Pour the batter into the prepared loaf pan and bake 40–45 minutes, or until a toothpick inserted into the center comes out clean. Ovens vary, so begin checking at 35 minutes.
  7. While the loaf bakes, make the glaze: whisk 1 cup powdered sugar with 2 tsp almond milk and 2 tsp lemon juice until smooth. Adjust thickness by adding more powdered sugar or a little more almond milk.
  8. Remove the loaf from the oven and let it cool in the pan for about 10 minutes. Transfer to a wire rack to cool completely.
  9. Drizzle the lemon glaze over the cooled loaf and allow it to set for a few minutes before slicing and serving.

How to Store the Lemon Loaf

Proper storage keeps this vegan lemon loaf moist and flavorful:

  1. Cool completely before storing to prevent condensation.
  2. Tightly wrap the loaf in plastic wrap or aluminum foil, or place it in an airtight container to keep air out.
  3. Refrigerate for up to five days. Chilling helps the flavors develop and preserves texture.
  4. For longer storage, freeze the loaf for up to three months. Wrap well in plastic and foil or use a freezer-safe bag. Thaw overnight in the refrigerator before serving.

Tips and Variations

  1. Use fresh lemons for the best, brightest flavor. Zest and juice fresh fruit rather than using bottled juice for maximum freshness.
  2. Ensure coconut oil is fully melted and warm (not hot) so it mixes smoothly with the wet ingredients.
  3. Bring almond milk and yogurt to room temperature so the batter mixes evenly and the coconut oil doesn’t solidify.
  4. Mix the batter gently and stop as soon as the ingredients are incorporated to avoid a dense loaf.
  5. Try adding chopped almonds, pecans, or dried cranberries for added texture and flavor.
  6. Make mini loaves or muffins by adjusting baking time—mini loaf pans and muffin tins will bake faster, so start checking sooner.
  7. Allow the loaf to cool completely before glazing so the glaze sets nicely without melting into the cake.
  8. Adjust glaze sweetness or tartness by increasing powdered sugar for a sweeter glaze or adding more lemon juice for extra tang.
  9. Serve warm or at room temperature with coffee, tea, or a lemony herbal infusion for a classic pairing.
