Tastes like cheat day, isn't cheat day. This protein powder is made with all real food ingredients. With four protein sources, including grass-fed, non-denatured whey from New Zealand, and free from artificial sweeteners.

Bright lemon meets sweet vanilla cake. Savor the nostalgic flavor of a soft, frosted birthday cake with a refreshing citrus twist.

Mix 1 scoop to 8 oz of milk using a frother or shaker bottle. Because we use real food ingredients, color and flavor may naturally vary.

Our quality assurance process for our nutritional and supplement products begins with collecting, from our suppliers, Certificates of Analysis (COAs) for our ingredients. We then retest the final product blend. We share our COAs because we believe the results are worth sharing.

Frequently Asked Questions

Most powders rely on whey alone, which gives you one amino acid profile and tends to upset digestion in larger doses. We use multiple real food protein sources in smaller amounts for a fuller amino acid range that's easier on your stomach. Whey and pea support muscle, chia adds fiber, and collagen supports skin, joints, and bones.

Four real food sources, depending on the flavor: grass-fed whey, pea, chia seed, and collagen. We blend them on purpose, because no single protein covers everything. Together they give a more complete amino acid profile than one source could alone.

It's far less likely to. Most powders use only whey, and a big dose of whey alone is what bothers most people. We use four to five proteins in smaller amounts, plus non-denatured whey with no casein and very little lactose, so even whey-sensitive people tend to do well.

We use organic powdered cream cheese, organic lemon, organic monk fruit extract, and organic vanilla extract to create a tasty flavor that tastes indulgent but still fits the nutritional profile of our other protein flavors (0g added sugar, 25g protein, etc.).

Reviews

Delicious!

"I love this flavor! It reminds me of the old version of lemon Girl Scout cookies with the frosting on the bottom 🍪🍋"

— Kelsey S. (5/5)

Smelled delicious but did not taste delicious

"I did not care for this flavor. Had a weird chemically aftertaste and was suuuuper sweet. My two sisters that I let try it said the same things. I'll stick to my double chocolate, best protein powder in the world!"

— DeeAnna S. (2/5)

20 STARS!

"This one is my absolute favorite! The weird thing is is that I can’t stand any of the other fruit flavored protein powders but this is my top choice out of everything they sell. Of course my favorite kinds of desserts are lemon ones and birthday cake flavored so go figure! 😅"

— April B. (5/5)

My new favorite flavor! I

"My new favorite flavor! I wasn't so sure about the lemon but it's amazing! Tastes like a lemon pound cake. I love using it in my overnight oats (breakfast for dessert anyone 😋). As always great ingredients and excellent service."

— Whitney B. (5/5)

Love!!

"Love this new lemon birthday cake!! I'm not a huge fan of lemon, but this was perfect, it's not a strong lemon flavor! I made protein muffins and they were really good! My whole family loved them and devoured them!"

— Tiera O. (5/5)

Great lemon flavor!

"I ordered this Lemon Birthday Cake protein not to drink it on its own, but to add it to other ingredients. It’s awesome in plain yogurt, cottage cheese, pancake mix, muffin mix and scones! It tastes natural and is subtle in flavor. We love it in our house!"

— Fitzpatrick (5/5)

A delicious & refreshing lemon protein powder!

"I love this new protein powder and it's now one of my fav's because I adore all things lemon! I use it in my daily chia seed pudding snack, with organic frozen blueberries and it's like I'm eating a slice of lemon birthday cake with blueberries on top! So good! Thank you!"

— Angela L. (5/5)

Blissful Yumminess

"The Lemon Birthday Cake is my absolute favorite flavor of Just Ingredients Protein Powder. By itself it is absolute blissful experience on my taste buds with it's rich and creamy lemoniness! It also adds that extra yumminess to my blueberry smoothies for a refreshing summer smoothie."

— Heather M. (5/5)

So Lemony!

"The Lemon Birthday Cake Protein Powder is so delicious. It has such a great lemon flavor. It was so good in a shake, but also good mixed with just water. It's definitely a new favorite!"

— Jacquelyn J. (5/5)

Lemon Birthday cake protein

"The lemon birthday cake protein is a little bit too sweet for me but it is good overall and I enjoyed it more than a lot of the other flavors like the caramel or the strawberry."

— Maria N. (4/5)

Q&A

How many grams of collagen account for the 20 total grams of protein? Dietician notes it is incomplete protein and doesn’t want me counting it toward my macro allotments.
At Just Ingredients, we value transparency, though some details are proprietary. Since our Protein Powder isn’t primarily a collagen supplement, we typically don’t disclose the exact amount of collagen.
Is this flavor limited edition or is it expected to be around for a while?
Great question! The Lemon Birthday Cake Protein Powder flavor is here to stay! It will be available year round, it is not seasonal.
Will there be a sample for this flavor and the Cookies and Cream?
We are planning on having the stick sizes in the future. Whenever a product is new, it takes a few months for those to be available.
I don’t drink any type of milk. What else can I mix this in? I don’t eat yogurt either.
You can mix this in water!
Is the lemon birthday cake protein gluten free
I am so happy to let you know it is!
