Ingredients You Will Need – Only 7 Pantry Staples

– Egg Whites – 2 egg whites (2 ounces or 6 tbsp): Crucial for structure of this high-protein treat. They give lift and fluffiness.
– Water – 2/3 cup: Makes batter smooth and moist.

How To Make Cinnamon Swirl Protein Cake – Step by Step

Step 1: Preheat and Prep Pan

Preheat oven to 390°F (200°C). Ensure oven is fully heated before mixing to ensure cake bakes evenly. Lightly spray small 4.5-inch nonstick pan with avocado oil or cooking spray – even with nonstick, light spray recommended so cake releases easily.

Step 2: Blend The Batter – 1 Minute

Combine oats, egg whites, water, protein powder, Stevia, and baking powder in blender. Pulse until consistency is smooth and resembles thick pancake batter. Don’t over-blend, just until smooth.

Step 3: Layering The Cinnamon Swirl – The Beautiful Part

Pour exactly half of batter into prepared small nonstick pan. Evenly sprinkle your tablespoon of cinnamon over this bottom layer, covering surface.

Step 4: Top and Create Swirl

Pour remaining batter over cinnamon layer to cover. Take a knife and gently pull it through batter a few times – just 2-3 strokes – to create beautiful marbled swirl effect. Do not over-mix cinnamon; few strokes are enough for gorgeous look.

Step 5: Bake and Rest

Bake for 12 minutes. Let cake rest for 5 minutes before slicing to allow structure to set properly. If your cake does not rise as expected, try switching brand of protein powder.

Pro Tips For Perfect Protein Cake Every Time

– Use Small Nonstick Pan: This recipe is designed for 4.5-inch pan. If you use larger pan, cake will be very thin. Small pan ensures thick, moist cake.
– Quality Protein Powder Matters: High-quality vanilla whey or plant-based protein that bakes well gives best results. Some cheap proteins don’t rise.
– Don’t Over-Swirl: Just few knife strokes create beautiful marbled look. Over-mixing blends cinnamon and you lose swirl.
– Let Cool Before Removing: Cool at least 5 minutes before removing from pan so it doesn’t tear.
– Light Spray Even For Nonstick: Ensures easy release.

Serving Suggestions – Make It Extra Special

Enjoy warm slice with:

– Greek Yogurt Dollop: Extra creaminess and more protein.
– Fresh Berries: Blueberries or raspberries for burst of color and antioxidants.
– Almond Butter Drizzle: Tiny drizzle for healthy fats and extra flavor.
– Hot Coffee or Tea: Perfect pairing for cozy breakfast.

Storage and Reheating

This cake stays fresh in refrigerator 3-4 days in airtight container. When ready to eat, pop slice in microwave for 30 seconds to bring back freshly-baked texture. Perfect for meal prep – make Sunday and enjoy all week!
