What You’ll Need
- 1 1/2 cups (180g) all-purpose flour (or white whole wheat flour)
- 1/2 cup (60g) vanilla or plain protein powder (whey, casein, or plant-based)
- 1 cup fresh or frozen blueberries
- 2/3 cup (135g) granulated sugar or preferred sweetener
- 2 large eggs
- 1/2 cup (120g) plain Greek yogurt (or Skyr, or dairy-free alternative)
- 1/3 cup (80ml) milk (dairy or unsweetened plant-based)
- 1/4 cup (60ml) neutral oil (canola, sunflower, or melted coconut oil)
- Zest of 2 lemons
- 1/4 cup (60ml) fresh lemon juice
- 2 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1 tsp vanilla extract
- 9×5-inch loaf pan
- Parchment paper (optional, for easy removal)
- Mixing bowls, whisk, spatula, measuring cups and spoons
Step-by-Step
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Lightly grease your loaf pan or line it with parchment paper for easy removal.
- Mix Dry Ingredients: In a large bowl, whisk together the flour, protein powder, baking powder, baking soda, salt, and lemon zest. Stir well to distribute the leavening agents and zest evenly.
- Mix Wet Ingredients: In a separate bowl, whisk together the sugar, eggs, Greek yogurt, milk, oil, lemon juice, and vanilla extract until smooth and well combined.
- Combine Wet and Dry: Pour the wet mixture into the dry ingredients. Stir gently with a spatula or wooden spoon until just combined; do not overmix. A few lumps are fine.
- Add Blueberries: Toss the blueberries with a tablespoon of flour (this helps prevent them sinking). Fold them gently into the batter, being careful not to burst them.
- Transfer and Smooth: Pour the batter into the prepared loaf pan. Smooth the top with a spatula.
- Bake: Bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs. If the top browns too quickly, tent with foil halfway through.
- Cool: Allow the bread to cool in the pan for 10–15 minutes. Then transfer to a wire rack to cool completely before slicing. This helps the structure set and prevents crumbling.
- Serve or Store: Slice and serve once cool. Store leftovers in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. For longer storage, freeze individual slices.
Common Mistakes
- Overmixing the batter: This can lead to tough, dense bread. Stir until just combined.
- Using too much protein powder: Excess protein powder dries out the loaf and can give a chalky texture. Stick to the recommended amount.
- Skipping the flour coating on blueberries: Without it, berries often sink to the bottom.
- Baking at too high or low a temperature: This affects rise and crumb. Always preheat the oven and use an oven thermometer if possible.
- Removing from the pan too soon: Hot bread is fragile and can fall apart if not cooled enough before transferring.
Tips
- Customize your protein: Both whey and plant-based protein powders work, but whey yields a lighter crumb while plant-based may make it denser. Adjust liquid slightly if using plant-based protein as it absorbs more moisture.
- Control sweetness: Swap the sugar for coconut sugar, honey, or a calorie-free sweetener if desired. Adjust the quantity to taste, especially if your protein powder is already sweetened.
- Boost fiber: Substitute half the flour with white whole wheat or oat flour for more fiber, but expect a denser loaf.
- Keep it moist: Greek yogurt is key for moisture and protein. Don’t skip it, but you can use Skyr or a thick dairy-free yogurt if needed.
- For extra lemon flavor: Add a teaspoon of lemon extract or more zest. You can also brush the cooled loaf with a little lemon syrup (equal parts lemon juice and sugar, simmered) for a tangy finish.
- Use frozen blueberries directly from the freezer: No need to thaw, but increase baking time by 5–8 minutes and check with a toothpick.
- Double the protein: Add a tablespoon of chia seeds or hemp hearts to the batter for a further protein and texture boost.
Troubleshooting
- Bread is dry or crumbly: Too much protein powder or flour, or overbaking, can cause this. Next time, measure ingredients carefully, avoid overbaking, and consider reducing protein powder by a tablespoon or adding a splash more milk.
- Bread is gummy or underbaked in the center: This often happens if the batter is too wet, the oven is too hot, or if underbaked. Check your oven temperature, and bake until a toothpick comes out clean. If using frozen berries, bake longer and tent with foil to prevent over-browning.
- Blueberries all at the bottom: Toss them in flour before folding into the batter, and avoid overmixing after adding them.
- Bread didn’t rise: Expired baking powder or baking soda, or insufficient mixing of leaveners, can cause this. Check freshness and ensure even mixing next time.
- Bread stuck to the pan: Use parchment paper or thoroughly grease the pan. Let cool before removing to avoid tearing.
- Overly dense texture: Overmixing, too little leavening, or too much protein powder can cause this. Mix gently and measure leaveners accurately.
Frequently Asked Questions
- Can I use almond or coconut flour instead of all-purpose flour?
These flours behave very differently and absorb more liquid. If you want a gluten-free option, try a 1:1 gluten-free flour blend. Using almond or coconut flour alone will require a different recipe ratio. - What’s the best protein powder for baking?
Whey protein isolate or concentrate works well for a soft crumb. Plant-based powders (pea, soy, rice) work too but may need more liquid for moisture. Unflavored or vanilla varieties are most versatile. - How do I make this bread dairy-free?
Use a plant-based protein powder, dairy-free yogurt (like coconut or almond-based), and a non-dairy milk. - Can I use bottled lemon juice?
Fresh lemon juice and zest provide the best flavor and aroma. Bottled juice works in a pinch, but the flavor will be less vibrant. - How can I store or freeze this bread?
Wrap cooled slices individually and freeze in a zip-top bag for up to 2 months. Thaw at room temperature or toast lightly to serve. - Can I make muffins instead of a loaf?
Yes! Divide batter among lined muffin tins and bake at 350°F (175°C) for 18–22 minutes, or until a toothpick comes out clean.
