Birthday cake protein bars

Birthday cake protein bars are nut butter and vanilla protein bars packed with funfetti spinkles. Made with only 7 ingredients, these no-bake protein bars are quick and easy to make. They are healthier than a slice of birthday cake, but taste just as delicious! These birthday cake protein bars are chewy, thick, and taste incredible.

My love for the birthday cake flavor is strong. In an effort to create a dessert with more nutrients but with the same delicious flavors, I did some experimenting. It wasn’t long before I came up with my new favorite easy, delicious treat: birthday cake protein bars.

Note: The idea for this recipe came from seeing the popularity of my Monster Cookie Protein Bars and Cookies and Cream Protein Bars!

What ingredients do I need?

I try to make all of my recipes as easy and simple as possible. That means there will usually be fewer than 10 ingredients, each of which are a pantry staple. This recipe only has 7 ingredients! Here’s what you’ll need:

  • Oats – For this recipe, you’ll need to to use oats to make an oat flour. Don’t let that intimidate you: to do this, all you need to do is put the oats in a blender or food processor for a few seconds. Oat flour will help create a thick and chewy texture for your protein bar. I use a standard old-fashioned or quick oats, just like I use for my easy protein oatmeal!
  • Cashew butter –Cashew butter is one of the most important ingredients for this recipe because it is creamy and serves as a binder to hold everything together. Cashew butter is similar to peanut butter in terms of nutrients (both nut butters have about the same number of calories and have protein and healthy fats), but they differ in flavor. This nut butter is still creamy, but the nutty flavor isn’t as strong, which is helpful for this recipe so the cookies and cream flavor can come through.
  • Vanilla Protein Powder – One serving of vanilla protein powder will add protein and some sweet vanilla flavors to these protein bars.
  • Honey – Adding honey will make these bars sweet and also serve as a binder to help hold these bars together.
  • Vanilla – I like to add vanilla to everything because I think it can make everything taste that much better. Plus, we’re basically making cookie dough and this will help get us to that flavor.
  • Cake Batter Extract - A few drops of cake batter extract will add the birthday cake flavor you're hoping for! More or less drops can be added according to your taste preference.
  • Sprinkles - Sprinkles are necessary for birthday cake bars! You can use whatever kind of sprinkles you like best.

Can I make substitutions to this recipe?

I haven’t tested many of the ingredient swaps, but I would bet you can make the necessary changes based on your dietary needs and available ingredients.

  • Oats – I use old-fashioned oats for this recipe, but you can use gluten-free or any kind of oats that match your dietary needs.
  • Cashew butter – Cashew butter is a really important ingredient to the FLAVOR of this recipe. However, any kind of creamy nut butter would work to get the correct consistency. Just beware if you use another ingredient it won’t taste exactly like cookies and cream.
  • Vanilla Protein Powder – The vanilla protein powder helps provide some extra vanilla flavor, so I would recommend using that or even a birthday cake flavor protein powder if you happen to have one!
  • Cake Batter Extract and Sprinkles – These two ingredients are going to help create the birthday cake flavor we’re looking for, so I would recommend keeping them!

What makes these bars nutritious?

These birthday cake protein bars are made with simple ingredients that taste delicious! The oats will add healthy carbohydrates and fiber to the bar. Cashew butter will add healthy fats and protein, and one serving of protein powder can add extra protein. Combining these ingredients with honey and toppings will create a bar that is packed with a balance of nutrients, potassium and calcium. Plus, each bar is only 93 calories (or 46 if you cut them in half)! This bar is a great pre-run, post-workout, afternoon, or late-night treat.

How long does it take to make this recipe?

This recipe takes about 10 minutes to make. This is a one-bowl recipe so you’ll need to dump all of your ingredients into one large bowl and stir! The hardest part of this recipe will be stirring everything until it’s completely mixed. This recipe is also no bake which means there isn’t an oven involved to cook the bars. The only “cooking” is the time when these bars will sit in the freezer to firm up. Trust me, this recipe is so quick and easy!
