Ingredients
Dry Ingredients
- 1 box lemon muffin mix (zero sugar or regular)
- ½ teaspoon baking powder (optional, for extra lift)
- ¼ teaspoon salt (optional, balances sweetness)
Wet Ingredients
- 1 bottle (11.5 oz / ~340 ml) high-protein milk or protein shake (vanilla or blueberry works best)
- 2 large eggs, room temperature
- ¼ cup neutral oil (avocado, light olive, or vegetable oil)
- 1 teaspoon pure vanilla extract
Flavor Boosters
- Zest of 1 large lemon
- 1 tablespoon fresh lemon juice
Mix-Ins
- 1 to 1½ cups fresh blueberries (or frozen, unthawed)
Optional Toppings
- Thin lemon slices or lemon zest
- Extra blueberries
- Coarse sugar or sugar substitute for a bakery-style top
Equipment Needed
- Large mixing bowl
- Whisk or spatula
- Muffin tin
- Muffin liners
- Measuring cups and spoons
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Line a standard 12-cup muffin pan with paper liners or lightly grease each cup. Proper prep ensures easy release and evenly baked muffins.
Step 2: Mix the Dry Ingredients
In a large bowl, add the lemon muffin mix. If using baking powder and salt, whisk them in now. This small step helps evenly distribute leavening and improves the muffin’s rise and crumb.
Step 3: Combine the Wet Ingredients
In a separate bowl or large measuring cup, whisk together the protein milk, eggs, oil, vanilla extract, lemon zest, and lemon juice. The lemon zest is key—it carries essential oils that deliver a bold citrus aroma and flavor that artificial lemon just can’t match.
Step 4: Create the Batter
Pour the wet ingredients into the dry ingredients. Gently fold with a spatula until just combined. Be careful not to overmix; a few small lumps are perfectly fine and actually help keep the muffins tender.
Step 5: Fold in the Blueberries
Lightly toss the blueberries with a teaspoon of the dry muffin mix (this prevents sinking), then gently fold them into the batter. Make sure they’re evenly distributed so every muffin gets plenty of fruit.
Step 6: Fill the Muffin Cups
Divide the batter evenly among the muffin cups, filling each about ¾ full. For a bakery-style finish, press a few extra blueberries on top and add a thin lemon slice or pinch of zest.
Step 7: Bake
Bake for 18–22 minutes, or until the tops are lightly golden and a toothpick inserted into the center comes out clean or with just a few moist crumbs. Avoid overbaking—protein-enhanced batters can dry out if baked too long.
Step 8: Cool
Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely. This helps set the structure while keeping the centers moist.
Texture and Flavor Notes
These muffins strike a beautiful balance:
• Tender crumb from the protein milk
• Bright citrus aroma from fresh lemon zest
• Juicy bursts of blueberry throughout
• Light sweetness that doesn’t overwhelm
Unlike many protein baked goods, these muffins stay soft even after refrigeration, making them ideal for make-ahead meals.
Nutrition Benefits
Thanks to the protein milk and eggs, each muffin contains a significant protein boost compared to standard muffins. Protein helps keep you fuller longer, supports muscle recovery, and stabilizes blood sugar—making these muffins far more satisfying than typical bakery versions.
They’re also lower in added sugar (especially when using a zero-sugar mix), making them a smart choice for anyone watching sugar intake without sacrificing flavor.
Storage & Meal Prep Tips
- Room Temperature: Store in an airtight container for up to 2 days
- Refrigerator: Keeps fresh for up to 5 days
