Ingredients You’ll Need

Gathering these wholesome ingredients couldn’t be simpler, and every item plays a key part in how these Collagen & Protein Oh Henry Chocolate Bars come together. Each ingredient brings something unique to the flavor, texture, or even the nutritional profile—so don’t shy away from using the best you can find!

Natural peanut butter: Delivers that iconic nutty creaminess and helps bind the bars together.
Honey or maple syrup: Offers natural sweetness and a subtle caramel note—choose maple syrup for a vegan-friendly option.
Coconut oil: Adds a silky texture while keeping the bars moist and holding everything together.
Vanilla extract: A splash of vanilla rounds out the flavor and enhances the chocolate and peanut butter notes.
Unflavored collagen peptides: Lends extra protein and collagen for support and structure, all without altering the taste.
Vanilla or chocolate protein powder: Gives a big protein boost and adds a hint of flavor—pick whichever you prefer!
Crispy rice cereal: Provides that classic light, airy crunch in every bite.
Chopped peanuts: Bring salty-sweet crunch and a little texture contrast.
Dark chocolate chips: Form the glossy, rich topping and make these bars totally craveable.
Coconut oil (for chocolate topping): Helps the chocolate layer stay smooth and snappable after chilling.

How to Make Collagen & Protein Oh Henry Chocolate Bars

Step 1: Prep Your Pan

Start by lining an 8×8-inch baking pan with parchment paper, letting a bit of the paper hang over the edges for easy lifting later. This step saves you from sticky disasters and ensures each Collagen & Protein Oh Henry Chocolate Bar pops right out when slicing time comes.

Step 2: Make the Peanut Butter Base

Over low heat, gently melt your peanut butter, honey (or maple syrup), and coconut oil together in a saucepan, stirring patiently until the mixture is smooth and glossy. This fragrant blend is the backbone of the bars—don’t let it bubble; just coax everything together until creamy.

Step 3: Add the Good Stuff

Take the saucepan off the heat and stir in vanilla extract, collagen peptides, and your favorite protein powder. The base will thicken as these mix in, making sure every Collagen & Protein Oh Henry Chocolate Bar packs a nutritional punch along with its irresistible flavor.

Step 4: Fold in the Crunch

Now it’s time for fun texture! Gently fold in the crispy rice cereal and chopped peanuts, evenly distributing for maximum crunch in every bite. Quickly press this mixture into your prepared pan; a spatula (or even damp fingers) helps spread it right to the corners.

Step 5: Make the Chocolate Topping

Pop the chocolate chips and a tablespoon of coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring well between each burst until smooth and glossy. Patience is key—if you rush, the chocolate could seize or burn.

Step 6: Pour, Spread, and Chill

Pour the melted chocolate over your peanut base, smoothing evenly with a spatula. Slide the pan into your fridge and let it chill for 1 to 2 hours (the hardest part: waiting!). The bars are done when the chocolate sets and your kitchen smells like a candy shop.

Step 7: Slice and Serve

Once firm, lift the whole block out using the parchment and use a sharp knife to cut into 12 generous bars—or make them bite-sized for sharing. Store them in the fridge until the craving hits!

How to Serve Collagen & Protein Oh Henry Chocolate Bars

Garnishes

To add some flair, sprinkle the tops of your Collagen & Protein Oh Henry Chocolate Bars with flaky sea salt just before the chocolate sets. You could also add a drizzle of contrasting nut butter or a handful of extra chopped peanuts on top for extra eye-catching crunch.

Side Dishes

Pair these bars with a hot cup of coffee, a frothy oat milk latte, or even a cold glass of almond milk. If you’re serving them at a gathering, a fruit platter or a bowl of fresh berries makes a refreshing, colorful side that balances all the chocolatey richness.

Creative Ways to Present

Get playful! Pop your Collagen & Protein Oh Henry Chocolate Bars into cupcake wrappers for easy, mess-free serving at parties. Stack them high on a rustic board, or cut them into mini squares for a homemade chocolate candy tray—perfect for gifting or sharing.

Make Ahead and Storage

Storing Leftovers

Keep any leftover bars chilled in an airtight container—they stay delightfully chewy and fresh for up to a week. Because they’re set with coconut oil and chocolate, they soften at warm temperatures, so the fridge is your best bet.

Freezing

Collagen & Protein Oh Henry Chocolate Bars freeze wonderfully! Layer them between pieces of parchment in a freezer-safe container. Whenever you want a protein-packed treat, defrost a bar at room temperature for about 10 minutes—easy and convenient.

Reheating

No reheating required here, but if you love a melty-chocolate experience, a quick 5-second zap in the microwave does the trick. Just keep a close eye so the chocolate topping doesn’t melt away!

FAQs

Can I use a different nut butter?

Absolutely! Almond butter or cashew butter would both work well, though the flavor and texture will vary slightly. Just be sure to use a natural, unsweetened version for the right consistency.

Are these bars gluten-free?

Yes—just check that your crispy rice cereal is certified gluten-free. Most of the other ingredients are naturally gluten-free, making these bars perfect for those with dietary restrictions.

Can I make these vegan?

Definitely! Swap the honey for maple syrup and choose a plant-based protein powder as well as dairy-free chocolate chips. Just keep in mind: collagen is not vegan, so you’ll want to leave it out or substitute with more protein powder if you’re fully plant-based.

How can I make these lower in sugar?

You can reduce the honey or maple syrup a bit (try using a few tablespoons less), and choose a dark chocolate with a higher cocoa percentage. Keep in mind, the texture and sweetness will change slightly, but the bars will still taste delicious!

Do I have to use coconut oil?

Coconut oil is ideal for texture and setting the bars, but you can swap in unsalted butter or a vegan butter alternative. Just know this may alter the flavor slightly, but your Collagen & Protein Oh Henry Chocolate Bars will still hold together just fine.

Final Thoughts

I can’t wait for you to try these Collagen & Protein Oh Henry Chocolate Bars—the blend of nostalgia and nutrition is truly irresistible. Whip up a batch to stash in your fridge and see how quickly they disappear. Your future snack breaks will thank you!
