Ingredients Overview
Key Ingredients:
-
Plain Greek Yogurt: The foundation of this cake. Use full-fat or 2% for richness, or 0% for fewer calories. Adds moisture, tang, and protein.
-
Eggs: Provide structure, binding, and lightness.
-
Almond Flour or Oat Flour: Keeps the cake tender and gluten-free, while adding fiber.
-
Vanilla Protein Powder: Essential for the high protein content and sweet flavor.
-
Baking Powder: Helps the cake rise gently.
-
Vanilla Extract: Adds warmth and classic cake aroma.
-
Optional Sweetener: Stevia, erythritol, or monk fruit if you prefer extra sweetness.
Notes on Ingredients:
-
If your protein powder is sweetened, you may not need additional sweetener.
-
Avoid whey isolate alone — it can make the cake rubbery. Blended or casein/whey protein powders work better for baking.
-
You can add lemon zest, cinnamon, or berries for flavor variations.

FAQs
Q1: Can I use flavored Greek yogurt?
Yes, but be aware of added sugars. Choose a sugar-free or lightly sweetened option if you want to keep the calorie and sugar count low.
Q2: What kind of protein powder works best?
Use a blended protein (whey + casein) or plant-based protein. Avoid pure whey isolate, which can make the texture rubbery.
Q3: Can I make this in a muffin tin?
Absolutely. Divide the batter between 6–8 muffin liners and bake for 15–18 minutes.
Q4: Is it freezer-friendly?
Yes. Slice, wrap individually, and freeze. Thaw overnight in the fridge or microwave for 30 seconds.
Q5: Can I make it egg-free?
Yes. Use flax eggs or a commercial egg replacer, but texture may be slightly less fluffy.
Q6: Can I use coconut flour?
Not recommended as a direct swap — it absorbs more moisture. If using, reduce the quantity and add more liquid.
Q7: How do I store leftovers?
Store in an airtight container in the fridge for up to 5 days. Enjoy chilled or briefly reheated.
