This Greek Yogurt Protein Cake is my go-to for when I want something sweet that doesn’t compromise my health goals. It’s soft, fluffy, and naturally high in protein, thanks to the blend of creamy Greek yogurt and protein powder. Whether I slice it up for an afternoon snack or serve it with fresh berries for dessert, this cake always hits the spot without the guilt.

Greek Yogurt Protein Cake

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

1 cup plain Greek yogurt (nonfat or full-fat)

2 large eggs

¼ cup milk of choice

⅓ cup granulated sweetener (or honey/maple syrup for non-keto)

1 cup oat flour (or almond flour for low-carb)

½ cup vanilla protein powder

1 teaspoon baking powder

½ teaspoon baking soda

½ teaspoon cinnamon (optional)

1 teaspoon vanilla extract

Pinch of salt

Directions

I preheat my oven to 350°F (175°C) and line an 8x8-inch baking pan (or loaf pan) with parchment paper.

In a large mixing bowl, I whisk together the Greek yogurt, eggs, milk, sweetener, and vanilla extract until smooth.

In a separate bowl, I stir the oat flour, protein powder, baking powder, baking soda, cinnamon (if using), and salt.

I gently combine the wet and dry ingredients, mixing until just combined—being careful not to overmix.

I pour the batter into the prepared pan and smooth out the top.

I bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.

After letting it cool slightly, I slice and enjoy it plain or with a topping of fresh berries.

Servings and timing

This recipe makes 9 servings.

Prep Time: 10 minutes

Cook Time: 25 minutes

Total Time: 35 minutes

Calories: About 150 kcal per serving

Variations

I swap oat flour for almond flour when I want a low-carb version.

Sometimes I mix in dark chocolate chips or chopped nuts for extra texture.

To switch up the flavor, I use different protein powder flavors like chocolate or caramel.

I add a swirl of almond or peanut butter before baking for extra richness.

For a fruity twist, I fold in blueberries or diced apples into the batter.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 5 days. When I want to reheat a slice, I pop it in the microwave for 10–15 seconds to bring back that just-baked softness. I’ve also frozen individual pieces—wrapped tightly—for up to 2 months. I just thaw them in the fridge overnight or heat straight from frozen.

FAQs

How much protein is in each slice?

That depends on the protein powder I use, but generally, each slice has around 10–12 grams of protein.

Can I make this cake dairy-free?

Yes, I replace the Greek yogurt with a dairy-free alternative like coconut or almond-based yogurt and use a plant-based milk.

Can I bake this in muffin tins?

Absolutely. I divide the batter into muffin tins and bake for 15–18 minutes, checking doneness with a toothpick.

What kind of protein powder works best?

I prefer using a whey or plant-based protein with a smooth texture and mild vanilla flavor. I avoid gritty or overly sweet powders.

Is this cake good for meal prep?

Yes, I often bake it on Sunday and keep slices in the fridge for a quick grab-and-go snack during the week.

Conclusion

This Greek Yogurt Protein Cake is one of those recipes I keep coming back to. It’s simple, nutritious, and hits the sweet spot between indulgent and healthy. Whether I’m looking for a post-workout snack or a better-for-me dessert, this cake delivers every time. I love how customizable it is, and it always leaves me feeling satisfied—not sluggish.
