This Hummingbird Protein Cake is inspired by a classic summer dessert in the South. Basically, Hummingbird Cake is a super-rich banana cake with chunks of pineapple, often smothered in cream cheese frosting, pecans, and shredded coconut. So yummy! However, the traditional recipe calls for 2 cups of sugar and 1 ½ cups of oil… so of course, I decided to come up with a lower-fat, low-sugar, protein-packed version (you know how I do). And guess what? It still tastes amazing!


Protein substitutions

To up the protein content, I replaced some of the flour with Quest Protein Powder in Vanilla Milkshake, a whey protein blend. This product combines whey isolate and casein and is just excellent for baking. However, you should be able to substitute a whey concentrate or soy isolate in this recipe. I cannot promise the result with other types of protein powder. Another flavor like cinnamon would also work well!

Flour substitutions

I also used coconut flour instead of cake flour or all-purpose flour to lower the carbs. If you’d prefer not to use coconut flour, just substitute twice as much (⅔ cup) of all-purpose flour, cake flour, gluten-free baking flour, fine oat flour, white sorghum flour, or cassava flour in this recipe.


Sweetener substitutions

The sweetener I use for is Pyure Organic Stevia Blend, a calorie-free blend of stevia and erythritol. I find it tastes much better than baking stevia or stevia extract and has no bitter aftertaste. It also doesn’t give the weird cooling sensation of pure erythritol (at least I don’t notice anything). That being said, feel free to substitute twice as much (two-thirds cup) of granulated sugar, baking stevia, granulated monk fruit, or granulated erythritol if you prefer!


Other substitutions

Instead of oil, I used unsweetened applesauce to lower the fat content. You can totally substitute oil for a more traditional-tasting cake if you don’t mind the added fat. Of course, you know there’s banana and pineapple in there! I used three very ripe mashed bananas and a cup of crushed pineapple for that classic “hummingbird” flavor.

The cream cheese frosting

The frosting is a simple cream cheese protein frosting made with Neufchatel cream cheese (can sub reduced fat cream cheese, fat free cream cheese, or whipped cream cheese ounce for ounce). It also calls for nonfat plain Greek yogurt, half a scoop of vanilla protein, sweetener, and a tiny bit of pure almond extract.

The almond extract is optional, but oh so good and highly recommended! Feel free to substitute dairy-free cream cheese for the cream cheese and Greek yogurt (ounce for ounce) if you need a dairy-free version! Of course, you’d also want to swap the whey blend for a vanilla plant-based protein blend.


Here’s the printable recipe for this Hummingbird Protein Cake! I’d love your comments below if you try it 😉

Still on that soup kick and this one's a goodie! I made this Chicken Wild Rice Soup dairy free, gluten-free, macro-friendly, and loaded with flavor. It took several tries to perfect this soup, and it's a winner! It's got hearty wild rice, tender shredded chicken, delicious mushrooms and fresh herbs all in a thicker cream broth.

I am feeling in the Valentine's Day spirit a little already (and always craving chocolate) so I made some vegan Protein Ferrero Rochers! They have a chocolate hazelnut filling with a roasted hazelnut in the center, surrounded by crushed vanilla wafer and coated in vegan milk chocolate. You can also roll them in crushed hazelnut like I did for extra crunch! While these aren't super high in protein, they offer a little boost. These chocolates are also lower in sugar, higher in fiber, and overall BIGGER than the world-famous Ferrero Rochers.

I just love a good minestrone soup. However, minestrone is lacking in protein, at least not enough to make a balanced meal... so this High Protein Minestrone Soup was born! It's got Italian spices like basil and oregano, diced tomatoes in flavorful broth, tender pasta, kidney beans, chickpeas, carrots, celery, onion, fresh garlic, and Italian seasoned ground turkey for some extra protein. This soup is comforting, nourishing, and very filling! Bonus - it's also gluten free, dairy free, and macro-friendly.
