Lemon Whey Protein Cupcakes

Lemon Protein Cupcakes With Healthy Frosting

I love lemony anything, and this lemon whey protein cupcakes recipe certainly fits the bill. As I mentioned in my Vanilla Protein Cupcakes Recipe, I added too much cream to my protein frosting, so it didn’t turn out quite as thick and creamy as I’d hoped. I’ve adapted the recipe for you guys though, so yours should turn out even better than mine!

Also, you may have noticed that my most recent recipes look a bit different. I’ve started implementing a new feature that will make my search listings in Google have more pizazz, and it has a few features that you guys might find kinda cool too. You now have the option to save my recipes to Ziplist, which gives you your own personal online recipe box, customizable shopping lists, and offers awesome deals and coupons on the grocery items on your list. Cool huh? There’s thousands of other participating recipe sites and blogs, so you can use Ziplist to gather all your favorite recipes in one place, easy buy the ingredients you need, and get some great deals too. Win!

Another feature that’s going to be on all my new recipes, is a star rating system. Just under the comment box on each of my new recipe posts, it says “rate this recipe”, and to the right are five little stars. I would love if you would rate my recipes so that other readers can see how popular I am ;)

Anyhoo, on to the lemon protein cupcakes recipe!

This lemon protein cupcakes recipe make 12 zesty whey protein cupcakes that are sure to impress. The perfect balance of sweet and sour, yummers!
(For Lemon Whey Protein Cupcakes)
  • ⅓ cup unsalted butter
  • 1 whole egg, 2 egg whites
  • ⅓ cup 2% plain greek yogurt
  • ½ cup buttermilk
  • ½ tsp vanilla extract
  • Juice and zest of 2 lemons
  • ¾ cup white flour
  • ¾ cup unflavored whey protein powder
  • ¼ cup coconut flour
  • ⅔ cup erythritol
  • 6 packs stevia powder
  • 1¼ tsp baking powder
  • ½ tsp baking soda
  • ¼ tsp salt
(For Lemon Buttercream Protein Frosting)
  • ½ cup unsalted butter
  • up to 2 Tbsp 10% cream
  • Juice and zest of 1 lemon
  • 1 tsp lemon oil extract
  • 1 cup unflavored whey protein
  • 1 cup powdered erythritol
  • 1 cup powdered sugar
  • 5 packs stevia powder
  • ¼ tsp salt
(For Lemon Protein Cupcakes)
  1. Preheat oven to 350 F (175 C)
  2. Cream the butter, then mix in the erythritol and stevia.
  3. Beat in the eggs, then the buttermilk and lemon juice and zest.
  4. Mix all of the remaining dry ingredients in a separate bowl.
  5. Bit by bit, mix the dry ingredients into the wet.
  6. Place cupcake liners in tray, give them a quick mist of olive oil spray to help avoid sticking.
  7. Pour batter evenly into cupcake liners, about ¾ of the way full.
  8. Bake in the oven for 13-15 minutes, be careful not to overcook or they'll get dry and rubbery.
(For Lemon Buttercream Protein Frosting)
  1. While the protein cupcakes are baking, grab another two bowls and your electric mixer, and mix up your protein frosting.
  2. Cream the butter first, and add in the lemon juice, half the zest, and lemon oil.
  3. Mix up the whey protein, erythritol powder, and icing sugar in another bowl.
  4. Slowly add the dry mix into the butter mix. Add some cream only if it's too thick, but be careful not to add too much or you'll get more of a sticky icing like me lol
  5. When protein cupcakes are baked and cooled, top them with your buttercream protein frosting, either with a piping bag or spatula, and garnish with a sprinkling of the rest of the lemon zest.
  6. Enjoy!

  • Your Great Aunt Elizabeth (who was a certified dietician) would have loved this recipe for any number of reasons- One being that she loved anything that was lemon flavoured.

    • Very cool, I wonder if I ever met her? I certainly inherited her love of lemon flavored goodies :)

  • These look awesome. When my new oven is working, these are one of the first things to be baked!
