Ingredients
Dry Ingredients
- 2 cups (250g) all-purpose flour
- ½ cup (50g) vanilla or unflavored protein powder
- ½ cup (100g) brown sugar
- 1 teaspoon baking soda
- 2 teaspoons baking powder
- ½ teaspoon salt
- 1 teaspoon ground cinnamon (optional)
Wet Ingredients
- 2 large eggs
- ½ cup (120ml) neutral oil (vegetable or light olive oil)
- ¾ cup (180g) plain Greek yogurt
- ¼ cup (60ml) milk (dairy or almond milk)
- 2 teaspoons vanilla extract
- 1 tablespoon lemon juice
- 1½ cups (200g) fresh or frozen blueberries
Streusel Topping (Cinnamon Crumble)
- ½ cup (60g) flour
- 3 tablespoons brown sugar
- 1 teaspoon cinnamon
- 3 tablespoons melted butter or oil
- Pinch of salt
Step-by-Step Instructions
Step 1: Preheat & Prepare
Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease with oil.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together:
- Flour
- Protein powder
- Brown sugar
- Baking powder
- Baking soda
- Salt
- Cinnamon
Make sure everything is evenly combined to avoid clumps of protein powder.
Step 3: Mix Wet Ingredients
In a separate bowl, whisk:
- Eggs
- Oil
- Greek yogurt
- Milk
- Vanilla extract
- Lemon juice
Whisk until smooth and creamy.
Step 4: Combine
Pour the wet ingredients into the dry ingredients. Mix gently with a spatula until just combined.
⚠ Do NOT overmix. Overmixing makes muffins dense instead of fluffy.
Toss the blueberries in 1 tablespoon of flour (this prevents sinking), then gently fold them into the batter.
Step 5: Make the Streusel
In a small bowl, combine:
- Flour
- Brown sugar
- Cinnamon
- Salt
Add melted butter and mix with a fork until crumbly. It should look like coarse sand.
Step 6: Fill & Top
- Fill each muffin cup about ¾ full.
- Sprinkle a generous amount of streusel topping over each muffin.
Press the crumble lightly so it sticks during baking.
Step 7: Bake
Bake for 22–28 minutes, or until:
- The tops are golden brown
- A toothpick inserted in the center comes out clean
Let muffins cool in the pan for 10 minutes, then transfer to a wire rack.

Add 1–2 tablespoons of chia seeds or replace ¼ cup flour with oat flour.
