Homemade Collagen Protein Bars Recipe: Peanut Butter or Chocolate

There are a lot of protein and snack bars on the market today. They fill a need for many of us: as an afternoon snack, before or after a workout, maybe on a road trip.

They’re popular for health-minded folks because they’re supposedly healthier than a cookie, biscuit or other common snacks. But are they really? While they can have decent levels of protein, often they contain too much sugar alongside a host of undesirable ingredients. Also, the type of protein can also be inferior, such as cheap soy protein.

Instead, consider making your own protein bar, with a superior protein like collagen that comes with its own set of benefits (see below). Here are two ways to make a collagen protein bar — chocolate as well as peanut butter collagen protein bars — that are balanced nutritionally and absolutely delicious.

You'll see why these DIY collagen protein bars deserve a spot in your snack routine, including on your summer travel protein snack list. They're also a cinch to make.

Health benefits of collagen

Why collagen? Collagen is a type of structural protein, and our bodies rely on our own production of it to keep our joints, ligaments, skin, hair and other organs in good shape. For example, did you know that up to 30 percent of all the protein in our body is collagen protein, and up to 70 percent of our skin, hair and nails is made from collagen?

Unfortunately, as we age past our 30s, our bodies naturally make less collagen, which can contribute to occasional joint discomfort or the appearance of crow’s feet. One way to help replenish our supply of collagen so that your body can make its own is to supplement with collagen powder, a convenient way to boost your intake of this special protein.

For example, Ancient Nutrition's Multi Collagen Protein powder — a main ingredient in each of these collagen bar recipes — can improve the appearance of crow's feet after 28 days and skin tone after 8 weeks. Support for skin elasticity and healthy skin tone is one of the most sought-after collagen benefits for women.

In addition, collagen supports exercise recovery, hair growth, gut lining integrity and healthy digestion.

Collagen bar ingredients

Beyond the collagen powder, it’s important to build a protein bar with great ingredients that are both good for you, are tasty and complement each other. These ingredients do just that.

Chocolate collagen protein bar ingredients:

• Healthy fats come in the way of the almond butter. Make sure it’s nice and creamy before using, so give it some good stirring before mixing in.

• Coconut flour also adds some healthy fat and mixes well for this bar.

• Sweetness comes via the maple syrup, and it’s lower on the glycemic index than sugar.

• Chocolate arrives from the Multi Collagen Protein Chocolate, cocoa powder and cacao nibs.

Peanut butter collagen protein bar ingredients:

• It starts with a cup of peanut butter. If you don’t like peanuts or allergic, you can use almond or sunflower seed butter.

• Sweetness comes from the maple syrup and vanilla flavor from Multi Collagen Protein Vanilla, which is then further complimented by vanilla extract.

• Dark chocolate chips are also used and mix well with the peanut butter flavor.

Nutrition facts

These bars deliver as protein bars as well as macronutrient bars, meaning they’re balanced between protein, fat and carbohydrates. They’ll also low in sugar, high in fiber and contain a high Daily Value (DV) percentage of many vitamins and minerals.

The peanut butter collagen protein bar contains 14 grams of carbs (2.6 grams of fiber and 7.7 grams of sugar), 18 grams of fat and 14 grams of protein for each 258 calorie serving. It contains nearly 20 percent DV of vitamin C, manganese, copper, niacin, magnesium, vitamin E and phosphorus.

The chocolate collagen protein bar contains 14 grams of carbs (2.7 grams of fiber and 9.1 grams of sugar), 10 grams of fat and 13 grams of protein for each 178 calorie serving. It contains nearly 20 percent DV of vitamin C, manganese, copper, riboflavin, vitamin E and magnesium.

How to make collagen protein bars

Making homemade collagen protein bars is surprisingly simple and requires just a handful of wholesome ingredients. Whether you choose the rich Chocolate Collagen Protein Bars or the classic Peanut Butter Collagen Protein Bars, the process is nearly identical and takes only a few minutes of hands-on preparation.

Start by combining the nut butter and maple syrup in a medium-sized bowl. Warm the mixture in the microwave for about 30 seconds, just until softened, then stir until smooth and fully combined. This creates the sticky base that helps hold the bars together.

For the chocolate version, stir in Multi Collagen Protein Chocolate, coconut flour, cocoa powder, vanilla extract and a pinch of flaky sea salt if desired. For the peanut butter version, combine the peanut butter mixture with Multi Collagen Protein Vanilla, coconut flour and vanilla extract. Mix until a thick dough begins to form.

Next, add unsweetened almond milk one tablespoon at a time, stirring between additions until the dough reaches a firm but pliable consistency. The mixture should hold together easily without being dry or crumbly.

Once the dough is ready, fold in the mix-ins. Add cacao nibs to the chocolate bars for a satisfying crunch, or stir in chocolate chips for the peanut butter bars. Be sure the dough has cooled slightly before adding the chocolate chips so they don't melt.

Line a loaf pan with parchment paper and firmly press the dough into an even layer. Sprinkle additional cacao nibs or chocolate chips on top and gently press them into the surface. Transfer the pan to the freezer for about 30 minutes, or until the bars are firm and easy to slice.

Remove the bars from the freezer and cut into 8 to 10 squares. Store them in an airtight container in the refrigerator for up to one week. These no-bake collagen protein bars make a convenient grab-and-go snack, post-workout bite, or healthier way to satisfy a sweet craving while adding extra protein to your day.
