The magic of this High-Protein Brioche Loaf Recipe lies in its simple but thoughtfully chosen ingredients. Each component plays a crucial role, whether it’s adding moisture, enhancing flavor, or creating that tender crumb texture you crave.

1 ½ Cups Full-Fat Cream Cheese: Adds creaminess and a subtle tang that complements the buttery notes.
¼ Cup Melted Unsalted Butter: Key to that traditional brioche softness and mouthfeel.
¼ Cup Heavy Cream: Intensifies moisture and contributes to a tender crumb.
¼ Cup EVO Oil (like avocado or light olive oil): Injects mild fruitiness and ensures a moist, tender loaf.
4 Tablespoons Sugar Sweetener: Adds a gentle sweetness without overwhelming the bread’s natural flavors.
½ teaspoon Salt: Balances sweetness and enhances all other flavors.
⅓ teaspoon Baking Soda: Helps the loaf rise while maintaining a fine crumb.
2 ½ teaspoons Baking Powder: Provides reliable lift for a light texture.
1 teaspoon Xanthan Gum: Acts as a binder and gives this gluten-free loaf structure and chewiness.

How to Make High-Protein Brioche Loaf Recipe

Step 1: Gather Ingredients and Preheat Oven

Start by bringing all your ingredients to room temperature. This simple step ensures that the batter mixes smoothly and the loaf bakes evenly. Then, preheat your oven to 320°F (160°C), setting the stage for the perfect bake.

Step 2: Whisk Eggs and Sweetener

In a large mixing bowl, whisk together the whole eggs and sugar sweetener until the mixture is light in color and slightly fluffy. This process incorporates air, providing lift and softness to your brioche loaf’s crumb.

Step 3: Add Wet Ingredients

Gradually blend in the cream cheese, melted butter, heavy cream, and extra virgin olive oil. Take your time for a silky-smooth batter; these ingredients contribute moisture, richness, and fat that make the loaf irresistibly tender.

Step 4: Blend Until Smooth

Continue whisking the batter until it’s completely smooth and lump-free. This step is crucial to achieve the signature brioche texture without any unpleasant lumps that might affect baking.

Step 5: Incorporate Dry Ingredients

Gently fold in the unflavored protein powder, baking soda, baking powder, salt, and xanthan gum until everything is evenly combined. This ensures consistent rise and structure throughout the loaf.

Step 6: Pour into Loaf Pan

Pour your prepared batter into a parchment-lined or silicone loaf pan. Smooth out the top with a spatula to create an even surface, which helps the loaf bake uniformly and look beautiful when finished.

Step 7: Bake to Perfection

Bake the loaf for 40 minutes in your preheated oven at 320°F (160°C). Once done, let it cool slightly before slicing to allow the structure to set perfectly. The result is a golden, high-protein brioche loaf with a tender crumb and rich flavor.

Garnishes

Consider topping slices with a smear of butter or cream cheese for classic indulgence, or try fresh berries and a drizzle of honey to brighten each bite. A sprinkle of nuts or seeds can add delightful crunch and extra nutrients.

Side Dishes

This brioche pairs wonderfully with a side of Greek yogurt or fresh fruit salad for a balanced breakfast. For savory options, consider serving alongside smoked salmon or avocado slices, turning it into a nutrient-packed meal.

Creative Ways to Present

Slice and lightly toast this loaf for sandwiches filled with turkey and spinach or nut butter with banana for a quick protein boost. You can also cube it for savory bread puddings or use it as a base for French toast with a high-protein twist.

Make Ahead and Storage

Storing Leftovers

Wrap any leftover brioche loaf tightly in plastic wrap or store in an airtight container. Kept at room temperature, it will stay fresh for up to 3 days, making it perfect for quick snacks or breakfast on the go.

Freezing

This high-protein brioche loaf freezes beautifully. Slice it before freezing so you can toast individual portions as needed. Wrap slices separately in parchment and then foil or plastic wrap to prevent freezer burn.

Reheating

To enjoy this loaf warm, simply toast slices or reheat wrapped in foil in a low oven at 300°F (150°C) for 10 minutes. This helps revive the moist, tender texture while preserving its rich flavor.

FAQs

Can I use a flavored protein powder instead of unflavored?

Using flavored protein powder can change the taste profile of your brioche loaf, sometimes adding sweetness or an artificial aftertaste. For the best and most versatile result, stick with unflavored protein powder, but feel free to experiment if you want a unique flavor twist.

Is this loaf gluten-free?

Yes! Since this recipe replaces traditional flour with protein powder and uses xanthan gum as a binder, it makes for a great gluten-free alternative that still delivers that classic brioche texture.

Can I substitute cream cheese with something else?

Cream cheese contributes moisture and tang, but you can swap it for mascarpone or Greek yogurt for slightly different textures and flavors. Keep in mind that changes in moisture content may affect the final bake, so adjust liquids accordingly.

How long does it keep fresh after baking?

Stored properly at room temperature in an airtight container, this loaf stays fresh for about 3 days. Refrigerating can extend its life but might dry it out, so consider freezing if you want to keep it longer.

What is the best way to slice the loaf?

Use a serrated bread knife to slice the brioche gently. This ensures clean cuts without squashing the soft crumb, helping you to preserve the loaf’s delicate texture.
