Ingredients

½ cup oats
2 egg whites (2 ounces or 6 tablespoons)
⅔ cup water
2 scoops vanilla protein powder (2 ounces)
1 teaspoon Stevia
1 teaspoon baking powder
1 tablespoon cinnamon

Instructions

Step 1: Preheat the oven to 390°F (200°C).
Step 2: Blend oats, egg whites, water, vanilla protein powder, Stevia, and baking powder together until the mixture is smooth and thick, similar to pancake batter.
Step 3: Pour half of the batter into a small nonstick pan about 4.5 inches in diameter. Sprinkle the cinnamon evenly over the batter.
Step 4: Pour the remaining batter on top of the cinnamon layer.
Step 5: Use a knife to gently swirl through the batter a few times, mixing the cinnamon slightly into the top layer.
Step 6: Bake for 12 minutes, then allow the cake to rest for a few minutes before serving.

Tips & Variations

Use maple syrup or honey instead of Stevia for a natural sweetener with a richer flavor.
Try adding chopped nuts or raisins into the batter for added texture.
For a dairy-free option, ensure your protein powder is plant-based.
Serve warm with a dollop of Greek yogurt or nut butter for extra creaminess.

Storage

Store leftover cake in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven before serving to maintain softness.

How to Serve

In the background, there is a clear glass bowl with a layered dessert featuring beige and white layers topped with a dusting of brown powder. The whole setup is on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Scale

Dry Ingredients

½ cup oats
2 scoops vanilla protein powder (2 ounces)
1 teaspoon Stevia
1 teaspoon baking powder
1 tablespoon cinnamon

Wet Ingredients

2 egg whites (2 ounces or 6 tablespoons)
⅔ cup water

Instructions

Preheat the oven: Set your oven to 390°F (200°C) and allow it to fully preheat while preparing the batter.
Blend the batter: Combine the oats, egg whites, water, vanilla protein powder, stevia, and baking powder in a blender. Blend until the mixture is smooth with a consistency similar to thick pancake batter.
Pour first layer: Grease a small nonstick pan approximately 4.5 inches across. Pour half of the batter into the pan evenly.
Add cinnamon layer: Sprinkle the tablespoon of cinnamon evenly over the batter in the pan.
Top with remaining batter: Pour the remaining batter gently on top of the cinnamon layer.
Create the swirl: Use a knife to gently pull through the batter a few times to create a slight swirl effect mixing the cinnamon with the batter.
Bake the cake: Place the pan in the oven and bake for 12 minutes until the cake is set and lightly golden on top.
Cool and serve: Remove the cake and let it rest for a few minutes before slicing and serving to allow flavors to settle.

Notes

Use a nonstick pan or grease the pan well to prevent sticking.
For extra sweetness, adjust Stevia to taste or add a drizzle of honey after baking.
Ensure not to overblend the oats to maintain some texture in the cake.
Check for doneness by inserting a toothpick – it should come out mostly clean.
Best enjoyed fresh but can be refrigerated for up to 2 days.
