Oatmeal Bars with Protein Powder

Jump to recipe

These no-bake oatmeal bars with protein powder are really easy to make and soooo tasty!  Today I’m partnering with Naked Nutrition and using their Vanilla Naked Whey Protein Powder, which has only three ingredients: grass-fed whey protein, organic coconut sugar, and natural vanilla flavor.  That’s it!  I LOVE that it doesn’t have any additives or artificial sweeteners because sometimes those can taste kind of fake.  This protein powder is slightly sweet, with a soft vanilla taste and blends into these homemade protein bars so easily.  I love these peanut butter oatmeal bars as a quick snack or breakfast replacement.  They are so easy to make and you can also substitute/add ingredients to your heart’s content (ditch the cardamom or add chia seeds – there are endless possibilities for making these bars even tastier).

10 Ways to Use Protein Powder

I think sometimes people associate protein powder with power lifters looking to really bulk up.  But I’ve bought and enjoyed protein powder for two decades and I’m just a vegetarian DIYer who gets engrossed in a project and forgets to eat, lol.  My worst offence: sometimes I’m too distracted to get around to breakfast.  So I make sure to incorporate quick, protein packed meals and snacks into my day – and protein powder is an easy and delicious way to boost my daily intake.  I love that the Naked Whey Protein Powder tastes great, only has three ingredients – with whey from cows that are grass fed (which results in a better quality whey) and raised without growth hormones.  Naked Protein has a variety of proteins, including vegan options, as well as dietary and workout supplements, all without any added junk.

    I was struggling to get enough calories and protein to sustain nursing and needed something quick first thing in the morning and late afternoon to avoid going hours without eating. Now I make a double batch of these every Sunday and they’re gone by the end of the week. My husband usually steals a couple 🙂
