This High-Protein Orange Cake is soft, moist, and bursting with fresh citrus flavor, with fragrant orange zest in every bite. Greek yogurt, eggs, almond flour, and protein powder give this cake a significantly more protein-rich profile than a traditional orange cake, while keeping the crumb tender and satisfying. It’s a delicious option for high-protein breakfasts, snacks, meal prep, or a lighter dessert.
Can This High-Protein Orange Cake Support Weight Loss Goals?
It can fit into a balanced eating pattern when portions are appropriate. The added protein from Greek yogurt, eggs, and protein powder can make a serving more filling, while using orange zest provides strong citrus flavor without requiring large amounts of juice or sugar. The cake still contains calories from almond flour, oil, and other ingredients, so portion size remains important.
Does This Recipe Fit a High-Protein Lifestyle?
Yes, this recipe is specifically designed to be high in protein, with Greek yogurt, eggs, almond flour, and protein powder working together.
Orange zest provides intense citrus flavor while keeping the amount of juice—and therefore the carbohydrates—moderate.
The recipe contains approximately 15 g protein per serving, depending on the protein powder and yogurt used.
For an even higher-protein serving, pair a slice with plain Greek yogurt or a high-protein yogurt topping.
Why This Recipe is Special
- High-protein: Multiple protein-rich ingredients make this more substantial than traditional cake.
- Bright orange flavor: Fresh zest creates intense citrus aroma and flavor.
- Moist & tender: Greek yogurt helps counteract the drying effect of protein powder.
- Lower-sugar option: Uses a reduced-sugar sweetener instead of a large amount of conventional sugar.
- Meal-prep friendly: Individual slices store and freeze beautifully.
My Personal Experience
- The orange zest makes this cake smell incredible while baking.
It gives the protein-rich batter a fresh citrus character without needing lots of juice. - Greek yogurt keeps the protein powder from making the cake dry.
The result is soft and tender rather than dense or chalky. - I love it as a breakfast-style cake.
A slice with Greek yogurt and fresh berries makes it feel like a complete morning treat. - A little cardamom makes the orange flavor even better.
It adds gentle warmth without overpowering the citrus.
Perfect For
This cake is ideal for high-protein breakfasts, post-workout-style snacks, meal prep, afternoon tea, healthy desserts, brunch, low-sugar eating plans, weekend baking, and convenient grab-and-go snacks.

Directions
- Preheat the oven — 5 minutes
Preheat to 175°C/350°F. Grease an 8-inch round cake pan and line the bottom with parchment paper. - Mix the dry ingredients — 2 minutes
Whisk almond flour, protein powder, baking powder, baking soda, salt, and optional cardamom. - Mix the wet ingredients — 3 minutes

Spread the batter evenly in the prepared pan. - Bake — 30–35 minutes
Bake at 175°C/350°F until the center is set and a toothpick inserted into the middle comes out with a few moist crumbs. Visual cue: The top should be lightly golden and spring back gently when touched. - Cool — 20 minutes
Let the cake rest in the pan for 10 minutes, then transfer it to a wire rack to cool completely. - Make the topping — 2 minutes
Stir Greek yogurt, orange zest, vanilla, and optional sweetener until smooth. - Finish — 3 minutes
