Ingredients
All-purpose flour: 1 ½ cups
Vanilla protein powder: ½ cup
Granulated sugar: ½ cup
Baking powder: 1 ½ teaspoons
Salt: ½ teaspoon
Plain Greek yogurt: ¾ cup
Large eggs: 2
Unsalted butter, melted: ¼ cup
Lemon zest: 2 tablespoons
Fresh lemon juice: ¼ cup
Vanilla extract: 1 teaspoon
For the Lemon Glaze:
Powdered sugar: 1 cup
Fresh lemon juice: 2-3 tablespoons
Instructions
1. 1. Preheat oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line with parchment paper.
2. 2. In a large bowl, whisk together flour, protein powder, sugar, baking powder, and salt.
3. 3. In a separate bowl, whisk together Greek yogurt, eggs, melted butter, lemon zest, lemon juice, and vanilla until smooth.
4. 4. Pour wet ingredients into dry ingredients and mix gently with a spatula until just combined; do not overmix. A few lumps are fine.
5. 5. Pour batter into prepared pan and smooth top. Bake for 45-55 minutes, until a toothpick inserted in center comes out clean.
6. 6. Cool in pan on a wire rack for 10-15 minutes, then remove from pan and cool completely.
7. 7. While loaf cools, make glaze: whisk powdered sugar with 2 tablespoons lemon juice; add more lemon juice ½ teaspoon at a time until desired consistency.
8. 8. Drizzle glaze over completely cooled loaf. Let set before slicing.
Notes
Measure flour by spooning and leveling to avoid dryness. Use room temperature eggs and yogurt for best texture. Zest lemons before juicing. For gluten-free, use a 1:1 gluten-free blend. For dairy-free, substitute yogurt with dairy-free yogurt and butter with coconut oil. Store in an airtight container at room temperature up to 4 days, refrigerate up to a week, or freeze up to 3 months.
