Base Protein Bar Recipe – Add Your Own Flavors!!

Base Protein Bar Recipe
Orange Almond Protein bars

Here is my base protein bar recipe (adapted from Jamie Eason’s Cinnamon Swirl Recipe). Once you have this part down all you need to do is add your own extracts to create your own flavor of bars! I usually do two to three teaspoons of extract per batch.

One Very Important Tip:

The homemade protein bars have no preservatives in them. So, if you make them you MUST keep them in the fridge or the freezer or they will spoil after one day left on the counter. I learned this the hard way!

I usually let them cool then put 4 squares in a Ziploc sandwich bag and stick them in the fridge or freezer. They will be good four to five days in the fridge otherwise stick them in the freezer.




  • 1 1/2 cups of oat flour (I grind my own oat flour in my food processor or blender from old fashioned oats, but if you are in a rush you can just use old fashioned oats instead of oat flour, the bars will just be a little chewier)
  • 3 scoops of vanilla whey protein (I like MRM brand Rich Vanilla flavor)
  • 1 tablespoon of baking powder
  • 1/2 teaspoon of salt
  • 1/3 cup of Stevia in the Raw or 1/2 cup of brown sugar xylitol/regular xylitol (I like Ideal brand)
  • 3 egg whites
  • 1 cup of unsweetened vanilla almond milk (I like Almond Breeze – the 40 calories per serving one)
  • 1/3 cup of unsweetened applesauce or a 3.5 ounces container of fruit flavored baby food (I used blueberry apple Gerber brand) – whatever flavor extract you use will determine what you want to use here
  • ¼ cup of Fage brand 0% Greek yogurt
  • 2-3 teaspoons of an extract of your choice (you could do 1/2 and 1/2, for example, 1 teaspoon of almond extract, 1 1/2 teaspoons of orange extract)

Add any other flavors or nuts of your choice. These could include nuts, peanut butter, unsweetened cocoa powder, instant coffee, etc.



Preheat the oven to 350 degrees. Spray an 8 X 8 inch Pyrex dish with non-stick spray.

1. In a large bowl combine (whisk together) the oat flour, vanilla whey protein, baking powder, the salt, and the Stevia in the Raw or brown sugar xylitol/regular xylitol.

2. In a medium bowl combine (whisk together) egg whites, unsweetened almond milk, the fruit flavored baby food or unsweetened applesauce, and the plain greek yogurt. Add any other flavors or nuts that you wish to add to your protein bars!

3. Add the wet ingredients to the large bowl with the dry ingredients. Mix dry and wet ingredients well.

4. Pour into the prepared pan.

5. Bake for 25 to 30 min or until knife comes out clean when placed in the center. Mine was closer to the 30 minutes but this will vary depending on your oven. Let cool for 10 min. Bars will be dense.


This recipe makes 16 squares.
