Name: Fluffy High-Protein Sheet Pan Pancakes Recipe
Prep time: 10 min
Cook time: 18 min
Total time: 28 min
Ingredients: 1 cup (120 g) oat flour; 2 scoops (60 g) vanilla protein powder; 2 teaspoons baking powder; ¼ teaspoon fine sea salt; 1 cup (240 g) plain Greek yogurt; 2 large eggs; ¼ cup (60 ml) milk; 2 tablespoons pure maple syrup; 1 teaspoon vanilla extract

If you want a protein-packed breakfast that feeds a crowd without hovering over the stove, these sheet pan pancakes are the answer.

The batter stirs together in one bowl, bakes as a single big slab, and comes out fluffy, tender, and loaded with protein. No flipping, no waiting, just cut into squares and eat.

Why These Protein Pancakes Work

These pancakes get their fluff from a blend of oat flour and protein powder, plus a good dose of Greek yogurt and eggs. The texture is soft and cakey, not dense or rubbery, like some protein pancakes can be.

Baking them in one sheet pan means zero standing time at the griddle. You get even browning and a consistent rise across the whole slab, and everyone sits down to hot pancakes at the same time.

Ingredients

1 cup (120 g) oat flour: use store-bought or blend rolled oats into flour (see note)
2 scoops (60 g) vanilla protein powder: a whey or plant-based blend works; vanilla keeps the flavor clean
2 teaspoons baking powder: for lift
¼ teaspoon fine sea salt
1 cup (240 g) plain Greek yogurt: full-fat or 2% gives the best texture
2 large eggs
¼ cup (60 ml) milk: any kind, dairy or plant-based
2 tablespoons pure maple syrup: plus more for serving
1 teaspoon vanilla extract

Variations / Substitutions

Dairy-free version: swap the Greek yogurt with a thick dairy-free yogurt and use plant-based milk plus a dairy-free protein powder.
Sweetener swap: use honey or sugar-free syrup instead of maple syrup; you may need to add 1 extra tablespoon of liquid if your sweetener is thin.
Mix-ins: fold ½ cup fresh blueberries or mini chocolate chips into the batter right before spreading it on the pan.
Flavor twist: use chocolate protein powder for a brownie-like pancake, then cut the maple syrup to 1 tablespoon.

Fluffy Sheet Pan Eggs are another breakfast you’d probably love if you enjoy these pancakes.

How To Make Fluffy High-Protein Sheet Pan Pancakes

Step 1: Whisk the Dry Ingredients

Preheat your oven to 350°F (175°C) and line a 13×18-inch sheet pan with parchment paper. In a large bowl, whisk together the 1 cup oat flour, 2 scoops protein powder, 2 teaspoons baking powder, and ¼ teaspoon salt.

Whisk until no clumps of protein powder remain. The mixture should look evenly blended and pale.

Step 2: Beat the Wet Ingredients

In a separate medium bowl, beat the 1 cup Greek yogurt, 2 eggs, ¼ cup milk, 2 tablespoons maple syrup, and 1 teaspoon vanilla together until completely smooth.

The yogurt needs to be fully incorporated so no white streaks are visible. The mixture will be thin enough to pour but thick from the yogurt.

Step 3: Fold the Batter Together

Pour the wet mixture into the dry ingredients. Using a spatula, gently fold everything together just until you no longer see dry flour. A few small lumps are fine.

The batter will be thick and spreadable, similar to cake batter. Overmixing can make the pancakes tough, so stop as soon as the streaks disappear.

Step 4: Bake the Pancake Slab

Scrape the batter onto the prepared sheet pan and spread it into an even layer all the way to the edges. Bake for 15 to 18 minutes, until the surface is set and lightly golden, and a toothpick inserted in the center comes out clean.

The edges might pull away from the parchment slightly. Let the slab cool in the pan for 5 minutes before lifting it out by the parchment.

Step 5: Slice and Serve

Transfer the pancake slab to a cutting board and slice it into 6 or 8 squares with a sharp knife or pizza cutter.

Serve the squares warm with extra maple syrup, fresh berries, or a dollop of Greek yogurt. The inside will be soft and fluffy.

A Few Tips for the Best Sheet Pan Pancakes

Use Greek yogurt at room temperature for easier mixing and a more even rise.
If your protein powder is unflavored, add an extra teaspoon of vanilla and an extra tablespoon of maple syrup to boost flavor.
Spread the batter evenly with an offset spatula; any thick spots take longer to bake.
For a meal prep option, bake once, cool, and refrigerate or freeze individual squares.

If you’re using a different sheet pan size, the bake time will shift a bit.

Pan Size	Batter Thickness	Bake Time
13×18-inch (half sheet)	about ¼ inch	15 to 18 minutes
9×13-inch (quarter sheet)	about ½ inch	20 to 22 minutes

Storing and Reheating Leftovers

Refrigerate: Keep squares in an airtight container for up to 4 days. They stay soft and moist.
Reheating: Warm them in a toaster oven at 300°F for 5 minutes, or microwave for 30 seconds. A flip halfway through helps them heat evenly.
Serve cold: They work like a soft granola bar straight from the fridge, good for busy mornings.

What to Serve With These Pancakes

A drizzle of warm maple syrup and a handful of fresh raspberries cut through the protein-rich batter nicely. A spoonful of extra Greek yogurt adds tang and even more protein, while a side of turkey sausage makes it a full meal.

Frequently Asked Questions

Can I use a different protein powder?

Yes, any vanilla or unflavored protein works. If you use chocolate powder, the pancakes will taste like brownies; reduce the maple syrup to 1 tablespoon.

Can I make this dairy-free?

Swap the Greek yogurt for a thick dairy-free yogurt and use plant-based milk plus a dairy-free protein powder. The texture will be slightly softer but still fluffy.

Can I double the recipe?

Yes, use two sheet pans and rotate them halfway through baking. The batter also scales easily if you want to make an even bigger batch.
