Ingredients

  • 1 cup all-purpose flour
  • 1 tsp baking powder
  • ¼ tsp salt
  • 1 cup fresh blueberries (reserve a handful for topping)
  • 1 cup nonfat Greek yogurt
  • 2 large eggs
  • ½ cup zero-calorie sweetener (or sugar alternative of choice)
  • 1 tbsp lemon zest
  • 3 tbsp fresh lemon juice
  • 1 tsp vanilla extract
  • Optional glaze: 2 tbsp powdered sweetener + 1 tbsp lemon juice

Instructions

1. Prep the oven and pan.

Preheat your oven to 350°F (175°C). Lightly spray a loaf pan with nonstick spray and line it with parchment for easy removal.

2. Mix the dry ingredients.

In a bowl, combine flour, baking powder, and salt. Whisk to aerate the mixture.

3. Coat the blueberries.

Take 1 tablespoon of the flour mixture and toss it with the blueberries. This prevents sinking during baking.

4. Whisk the wet ingredients.

In a separate bowl, whisk together Greek yogurt, eggs, sweetener, lemon zest, lemon juice, and vanilla until smooth and creamy.

5. Combine wet and dry.

Add the dry mixture into the wet and stir gently until just combined. Avoid overmixing.

6. Fold in the blueberries.

Carefully fold in the coated blueberries, distributing them evenly.

7. Pour into the pan.

Pour the batter into your prepared loaf pan, smoothing the top. Add extra blueberries on top for visual appeal.

8. Bake to perfection.

Bake for 45–55 minutes or until a toothpick inserted into the center comes out clean.

9. Cool completely.

Let the loaf cool in the pan for 10 minutes, then transfer it to a cooling rack.

10. Optional glaze.

Mix powdered sweetener and lemon juice, then drizzle over the cooled loaf for added brightness.

Useful Professional Tips

A key to maintaining moisture is not overbaking. As soon as a toothpick comes out clean or slightly moist, remove it from the oven. Leaving it in too long can dry out the loaf.

When zesting lemons, avoid the white pith beneath the skin. Only the yellow layer contains the essential oils that provide vibrant flavor. Using a microplane is the best way to achieve fine zest.

Blueberries release moisture as they bake. Tossing them in flour helps suspend them evenly through the loaf instead of allowing them to sink to the bottom.

Greek yogurt is essential in this recipe for its thick consistency. If substituting with regular yogurt, you may need slightly more flour to achieve the same texture.

Allowing the loaf to cool completely is crucial. Warm loaves crumble easily and can appear gummy. Once cooled, the structure sets perfectly.

Storage, Freezing & Meal Prep

This loaf stores beautifully. Keep it in an airtight container at room temperature for 24 hours or refrigerate up to 5 days. For longer storage, wrap slices individually and freeze for up to 2 months. Thaw slices at room temperature or warm them gently in the microwave.

The loaf’s flavor deepens after a few hours, making it even better the next day — ideal for weekly meal prep or healthy breakfast planning.
