Lemon Poppyseed Protein Cake Bars

you new go-to lemon dessert is here and it’s amazing- Lemon Poppyseed Protein Cake Bars! i have an ongoing obsession with all things lemon, whether that be sweet or savory!

Lemon Poppyseed Protein Cake Bars make the PERFECT freezer treat or snack for this summer.

lemon is so fresh and it really shines through in this recipe.

the base does indeed include vanilla protein powder and it’s sweetened with dates.

i did add some simple mills frosting to the top to give the bars a cake vibe, but if you’re looking to keep these more naturally sweetened, then you can omit!

the poppyseeds are totally optional too and not necessary. lemon poppyseed is just such a fun flavor combo and something that i really enjoy.

Lemon Poppyseed Protein Cake Bars should be stored in the freezer and thawed a bit before eating.

while you CAN store them in the fridge, the texture will be quite soft and not as firm as the bars are meant to be.

however, if that’s what you prefer then go for it! i’m just a huge fan of a sturdy texture when it comes to protein bars.

as far as vanilla protein goes, use whatever you would like! we have a huge container of garden of life and love it.

you will need 62g total, so 31g per scoop.

here’s everything you need to make Lemon Poppyseed Protein Cake Bars

oat flour

vanilla protein

large medjool dates

runny tahini or runny almond butter

lemon juice

lemon zest

dairy free milk


vegan vanilla frosting

that’s it! really simple and you can find all of these ingredients at basically every grocery store, nothing fancy!

  1. Thank you for this amazing recipe! I made these and am in love. I used Nuzest vanilla protein and a couple less dates than called for (I ran out, shock horror!!) but it was plenty sweet. Brilliant!
