Now I’m not talking 20g of fiber in one bar here, because that really would be too much. We want to feel full, but not poop in another 10 minutes, haha (okay it wouldn’t be 10 mins, but you know what I mean 😛).

The fiber in these bars keeps you full a little longer, and also helps you meet that daily fiber goal of at least 25-30. Not too massive a bar here that it replaces a meal, but just something to snack on or maybe as a simple dessert.

Ingredients for High Fiber Protein Bars:

These high fiber protein bars are made with simple healthy ingredients with no extra sugar, and great for a quick homemade snack.

Oat Flour – You can make your own by blending rolled oats in a high speed blender
High Fiber Cereal – I used Fiber One
Chia Seeds
Flax Seeds
Vanilla Protein Powder for high protein fiber bar recipe. I recommend the Quest Vanilla .
Unflavored Protein Powder to replace some of the flour (and carbs) in the recipe for a slightly lower carb high protein snack recipe. I recommend the Multi-purpose mix protein powder from Quest Nutrition.
Unsweetened Almond Milk
Sweetened Peanut Butter I used Grandma’s PB Fudge flavor Almond Butter from American Dream Nut Butter.
It’s lower fat and higher protein than normal, and just amazing (code HAYLSKITCHEN gives you a discount on these) in this protein bar recipe.
ADNB has a lot of other flavors that would go well here too.

And a white chocolate topping here for these protein bars.

White Chocolate Chips – I use sugar free white chocolate chips from Lily’s here for the contrast.
But another sugar free regular chocolate chip option is Lakanto (same discount here too) or Lily’s!
A bit of Coconut Oil

How to make Fiber Bars with Protein Powder

These homemade protein fiber bars are super easy to make – just mix all the ingredients in a bowl, press into a pan, and then cut!

Combine all the dry ingredients in a bowl –

Add in the peanut butter and milk (little at a time) and mix!
Add milk little at a time. Too much at once will make the mix too runny.

Press down into a parchment-lined loaf pan.

Chill in the freezer for about 10 minutes, then slice into bars.
You can slice immediately, but freezing makes them hold shape better.

Melt chocolate in the microwave with a bit of coconut oil.
Melt in intervals of 15 seconds, stirring every now and then so it doesn’t burn.
Drizzle on the bars.

To store Homemade Protein Fiber Bars

These healthy protein fiber bars can be stored on the counter top for a few hours, or in the fridge for 4 days; Use an airtight container.

You can also freeze these high fiber protein bars in airtight sealed container, or individually wrapped in plastic wrap and placed in zipper bag; Fiber snack bars should keep for 2 or 3 months. Be sure to let them thaw on the counter before eating!

I would recommend making this recipe with the ingredients (and brands) listed, but here’s some options for a healthy homemade fiber protein bar:

Unflavored Protein Powder: Oat Flour or Almond Flour, but use less milk;
