Vanilla Protein French Toast – A Cozy, High-Protein Breakfast Favorite
French toast doesn’t have to be a sugar bomb. With a few smart swaps, you can turn it into a protein-packed breakfast that still tastes like a weekend treat. This Vanilla Protein French Toast is fluffy in the middle, golden on the outside, and lightly sweet with warm vanilla.
It’s quick enough for weekdays and satisfying enough for brunch. Top it your way and you’ve got a balanced meal that actually keeps you full.
Ingredients
Method
- Make the custard. In a large bowl, whisk eggs, milk, vanilla extract, cinnamon, and salt. Sprinkle in the protein powder gradually, whisking until smooth with no lumps. If needed, use a blender for a silky mixture.
- Check sweetness. Taste the custard. If your protein powder isn’t sweet, add a little maple syrup or preferred sweetener and whisk again.
- Preheat the pan. Heat a large nonstick skillet or griddle over medium heat. Add a small pat of butter or a light swipe of oil so the surface is coated.
- Soak the bread. Dip each slice into the custard for 10–15 seconds per side. Let excess drip off. Thick or stale bread may need a few extra seconds; avoid soaking so long that it falls apart.
- Cook to golden. Place the soaked slices on the hot pan. Cook 2–3 minutes per side, until golden brown and slightly crisp on the edges. Adjust heat if it’s browning too fast.
- Serve warm. Stack on plates and add your favorite toppings. For more protein, top with Greek yogurt or a dollop of cottage cheese.
- For a crowd. Keep finished slices warm on a baking sheet in a 200°F (95°C) oven while you cook the rest.

- Protein powder upgrades the custard. Mixing vanilla protein powder into the egg-milk base adds body and sweetness without extra sugar. It also helps the custard cling to the bread for better browning.
- Thick bread means custardy centers. Slices like brioche, Texas toast, or sturdy sourdough soak up the mixture without falling apart, giving you that perfect soft middle and crisp edges.
- Balanced flavors, simple ingredients. Vanilla, cinnamon, and a pinch of salt round out the sweetness and make the protein powder taste like a natural part of the recipe.
- Quick cook, big payoff. A hot skillet or griddle creates a caramelized crust in minutes, while the inside stays tender and custardy.
- Flexible for any diet. Works with dairy or dairy-free milk, and you can swap bread types depending on your goals—gluten-free, whole grain, or classic brioche.
What You’ll Need
- Bread: 4–6 thick slices (brioche, challah, Texas toast, sourdough, or sturdy whole grain)
- Eggs: 3 large
- Milk: 3/4 cup (dairy or unsweetened almond/oat milk)
- Vanilla protein powder: 1 scoop (about 25–30 g; whey or plant-based)
- Vanilla extract: 1 teaspoon
- Cinnamon: 1/2 teaspoon
- Salt: A pinch (about 1/8 teaspoon)
- Sweetener (optional): 1–2 teaspoons maple syrup, honey, or zero-calorie sweetener if your protein isn’t sweetened
- Butter or oil: For the pan (1–2 tablespoons)
- Toppings (optional): Fresh berries, banana slices, Greek yogurt, a drizzle of maple syrup, chopped nuts, or a dusting of powdered sugar
How to Make It
- Make the custard. In a large bowl, whisk eggs, milk, vanilla extract, cinnamon, and salt.
Sprinkle in the protein powder gradually, whisking until smooth with no lumps. If needed, use a blender for a silky mixture.
- Check sweetness. Taste the custard. If your protein powder isn’t sweet, add a little maple syrup or preferred sweetener and whisk again.
- Preheat the pan. Heat a large nonstick skillet or griddle over medium heat.
Add a small pat of butter or a light swipe of oil so the surface is coated.
- Soak the bread. Dip each slice into the custard for 10–15 seconds per side. Let excess drip off. Thick or stale bread may need a few extra seconds; avoid soaking so long that it falls apart.
- Cook to golden. Place the soaked slices on the hot pan.
Cook 2–3 minutes per side, until golden brown and slightly crisp on the edges. Adjust heat if it’s browning too fast.
- Serve warm. Stack on plates and add your favorite toppings. For more protein, top with Greek yogurt or a dollop of cottage cheese.
- For a crowd. Keep finished slices warm on a baking sheet in a 200°F (95°C) oven while you cook the rest.
Storage Instructions
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
Place parchment between slices to prevent sticking.
- Freeze: Lay slices on a sheet pan to freeze individually, then transfer to a freezer bag for up to 2 months.
- Reheat: Toast in a toaster or air fryer at 350°F (175°C) for 3–5 minutes, or bake on a sheet pan at the same temperature until warmed through. Avoid microwaving if you want to keep the edges crisp.
Health Benefits
- Higher protein, better satiety. The combination of eggs and protein powder helps stabilize blood sugar and keeps you full longer than traditional French toast.
- Customizable carbs and fiber. Use whole-grain or sprouted bread for more fiber, which supports gut health and steady energy.
- Lower sugar potential. Because the protein powder adds sweetness, you can go lighter on syrup. Fresh fruit and cinnamon enhance flavor without adding much sugar.
- Flexible fats. A small amount of butter improves flavor and absorption of fat-soluble vitamins, while avocado oil or coconut oil works if you prefer dairy-free or higher smoke point options.
- Micronutrients from eggs. Eggs add choline, B vitamins, and essential amino acids—key players for brain and muscle function.
Pitfalls to Watch Out For
- Gummy centers. This usually means the slices were soaked too long or cooked on heat that’s too high.
Aim for medium heat and moderate soak time.
- Grainy custard. Some protein powders clump. Whisk slowly while sprinkling in the powder, or blend the custard for 10–15 seconds.
- Overly sweet. Taste your custard before adding extra sweetener. Many vanilla protein powders are already sweetened.
- Bread falling apart. Use day-old or slightly stale bread, or choose sturdier slices like sourdough or thick-cut brioche.
- Burnt edges. Protein browns faster than plain custard.
Keep heat at medium and add a touch more fat to the pan if needed.
Variations You Can Try
- Cinnamon Roll French Toast: Add 1 teaspoon extra cinnamon and a swirl of Greek yogurt mixed with a little maple syrup on top.
- Blueberry Burst: Fold a handful of fresh or frozen blueberries into the custard just before dipping, or top with warm berries heated in a splash of water.
- Almond Vanilla: Swap half the vanilla extract for almond extract and top with toasted sliced almonds.
- Chocolate Protein Twist: Use chocolate protein powder, add a pinch of cocoa, and top with strawberries.
- Dairy-Free: Use almond or oat milk and a plant-based protein powder; cook in coconut oil.
- Gluten-Free: Choose a sturdy gluten-free bread to avoid crumbling. Slightly stale is best.
- Extra Protein Stack: Serve with a side of turkey bacon or scrambled egg whites, or spread a thin layer of peanut butter between slices.
FAQ
What kind of protein powder works best?
Whey isolates blend smoothly and brown nicely, but many plant-based powders work well too. If using plant-based, look for a fine texture and avoid gritty blends.
Start with one scoop and adjust milk to keep the custard pourable.
Can I make this without eggs?
Yes. Replace each egg with 3 tablespoons aquafaba or use a commercial egg replacer, and increase protein powder slightly if the mix seems thin. The texture will be a bit less custardy but still delicious.
Why is my French toast soggy?
Your bread may be too soft or overly soaked, or your heat may be too low.
Use thicker, slightly stale slices, dip briefly, and cook over medium heat until both sides are deeply golden.
Do I need sugar in the custard?
Not necessarily. Most vanilla protein powders are sweetened. Taste the mixture before adding maple syrup or other sweeteners.
Can I bake it instead of pan-frying?
Yes.
Arrange soaked slices on a greased sheet pan and bake at 375°F (190°C) for 10–12 minutes, flipping halfway. Finish with a quick broil for extra browning.
How can I add more fiber without changing the taste?
Use whole-grain bread, top with berries, or stir 1 tablespoon ground flaxseed or chia into the custard. If adding seeds, let the mixture sit 2 minutes to hydrate.
What toppings pair best with the vanilla flavor?
Fresh berries, banana slices, Greek yogurt, a light drizzle of maple syrup, toasted almonds or pecans, and a dusting of cinnamon all pair beautifully with vanilla.
Can I meal prep this?
Absolutely.
Cook a batch, cool completely, and refrigerate or freeze. Reheat in a toaster or air fryer for an easy weekday breakfast.
Is there a way to reduce calories?
Use a low-calorie bread, unsweetened almond milk, a lean protein powder, and cook with a light spray of oil. Keep toppings simple—fresh fruit instead of heavy syrups.
How do I avoid the protein taste being too strong?
Use a brand you enjoy in shakes, add extra vanilla and cinnamon, and don’t overpack the scoop.
A pinch of salt also balances the flavor.
In Conclusion
Vanilla Protein French Toast gives you the comfort of a diner classic with the staying power of a high-protein breakfast. It’s simple, flexible, and easy to fit into different diets and schedules. With the right bread, a smooth custard, and steady heat, you’ll get golden slices that taste indulgent but fuel your day.
Keep a few slices in the freezer and you’ve got a fast, feel-good breakfast anytime.
