Ingredients used to make these Collagen Lemon Protein Bars

_{**I've linked some of these ingredients to amazon.com to give you an idea of what they are, but you should also be able to find them in your local grocery store (usually, the natural & organic food section).

• Collagen Peptides - Collagen Peptides Powder is a powdered supplement that is made of hydrolyzed collagen peptides — small chains of amino acids that help support healthy hair, skin, nail, bone and joint health. I used Vital Proteins Collagen Peptides Powder for this recipe. You can use other brands of collagen peptides and get the same result.
  • Collagen peptides protein powder is the key ingredient that gives these protein snacks their characteristic cookie-like consistency, and other protein powders won't give you the same chewy texture. Collagen also dissolves very easily compared to other protein powders (i.e. whey, casein, pea, hemp, brown rice, egg protein, etc), so you'll have to add more liquid like almond milk or water to hold the protein dough together if using a replacement.

• Coconut Flour - Coconut flour is a great low carb flour that is gluten-free, wheat free, and grain-free. Coconut flour is also nut-free (even though it's called coco-nut) because it's made from coconut flesh (which is a fruit, not a nut) that’s been dried and then grind into small flour particles. Here is a brand of coconut flour I like to use. (see substitution notes in the below section!)

• Sugar of Choice – I used monk fruit sweetener in this recipe to keep this recipe low-sugar and low carb, but raw cane sugar, coconut, date, and maple sugars are perfectly acceptable substitutes. 

• Lemon Curd - lemon curd is a sweet creamy pudding like cream that's made with lemon, egg yolks, sugar, and sometimes butter. You can make your own, but I used storebought, like this one

• White chocolate chips - you can use any white chocolate chips (or chopped white chocolate), but to make these low-carb, use a lower sugar, stevia sweetened brand instead. For a dairy-free, vegan alternative, try this brand.

Recipe Variations and Optional Add Ins:

• Feel free to experiment with natural flavoring / extracts. Add a teaspoon of vanilla extract (I didn't feel like it was essential so I left it out in this recipe), or other flavorings or extracts, such as lemon extract or almond extract

Just keep in mind that some extracts contain alcohol, and since this is a no-bake recipe, the alcohol won't have a chance to fully evaporate. If serving this to kids, or if you're sensitive to alcohol, be sure to use non-alcoholic extracts or flavorings. Here are some non-alcoholic brands, here: Non-alcoholic peppermint extract, non-alcoholic vanilla extract

COLLAGEN PEPTIDES FAQ:

ARE COLLAGEN PEPTIDES VEGAN?

Most commercial forms of collagen peptides are not suitable for vegan diets, as collagen is most abundant in skin, nails, bones and ligaments and is thus sourced from animals. The Vital Proteins Collagen Peptides Powder I used in this recipe was sourced from the hides of grass-fed, pasture-raised cows.

Notes on Substitutions

Can I use other Protein Powders if I don't have Collagen Powder?

For most recipes, collagen peptides should not be replaced with other protein powders, and I have not tried using other types of protein powders (i.e. whey, casein, pea, hemp, brown rice, egg protein, etc) in this recipe. This is because Collagen Peptides contribute a different texture to the recipe than other protein powders. In my experience, collagen powder adds a denser, chewier consistency to most protein powder recipes which I think resembles a chewy sugar cookie texture.

If you decide to substitute, just keep in mind that you'll need to add additional liquid (almond milk or water) to this recipe to get the protein dough to hold together. Also, you won't get the cookie-like texture you see in the photos since collagen is what creates that chewy consistency.

Can I substitute other flour Alternatives for coconut flour?

Collagen is a fussy ingredient, so I highly recommend that you DON'T SUBSTITUTE coconut flour in this particular recipe (including almond flour and oat flour). It's not that these flours don't work, but you'll have to be okay with playing around with the entire recipe, like adding more flour, more nut butter and also less liquid -- since coconut flour absorbs 2x 3x more liquid than other flour substitutes.

How to Make this Healthier

• Make this even healthier by adding a handful of nuts, seeds and old-fashioned oats to add texture and nutrition. Even better, add a tablespoon of ground flaxseed, hemp seeds, or chia seeds.

How to Store

• You can keep the protein bars out at room temperature for 1-2 days but for the best texture, it's best to store these protein bars covered in the fridge. They'll be fresh for up to 5-7 days.
• These protein bars also freeze very well! Seal them inside an airtight container or Ziploc bag and freeze them in a single layer so that they don't stick together. I recommend double-bagging if you want to keep out the fridge smell. They can be frozen for up to 4 months.

Final Tips

• Collagen peptides protein powder dissolves very easily compared to other protein powders so try not to add additional water or liquid to the protein dough until the very end. The collagen dough will soften up noticeably during the kneading process, so if you add extra liquid you may end up with a very soft protein dough.
• Make sure you check out the substitution section above if you decide to sub any of the ingredients.
