Ingredients

• 1¼ cups old-fashioned rolled oats (use gluten-free oats if needed)
• ½ cup creamy natural peanut butter (no-stir brands like Justin’s work great)
• ½ cup honey or pure maple syrup (maple for a vegan twist)
• ¾ cup dark chocolate chips (70% cacao recommended)
• 2 tbsp coconut oil (helps the chocolate set smoothly)
• 1 tsp pure vanilla extract (opt for Nielsen-Massey if you have it)
• Pinch of fine sea salt (enhances the chocolate-nut flavor)

Tip: Measure the oats by gently spooning them into the cup—don’t pack them down. If your peanut butter is on the runny side, chill it briefly so the bars hold together better.

Directions

1. Line an 8×8-inch baking pan with parchment paper, letting the edges hang over for easy removal.
2. In a medium saucepan over low heat, whisk together peanut butter, honey (or maple syrup), and coconut oil until smooth and glossy—about 2–3 minutes. Stir constantly to prevent scorching.
3. Remove from heat and stir in vanilla extract and a pinch of sea salt. The aroma should be warm and nutty—just like grandma’s kitchen.
4. Fold the rolled oats into the warm mixture with a sturdy spatula, ensuring every flake is coated. This step gives structure and that lovely chew.
5. Transfer half of the oat-peanut mixture into the prepared pan. Press firmly with the back of a spatula or a piece of parchment until it’s compact—this helps the bars hold shape.
6. In a small microwave-safe bowl, melt the chocolate chips in 20-second bursts at 50% power, stirring between each until silky. Stir in any leftover coconut oil to smooth it out.
7. Pour the melted chocolate over the first oat layer, tilting the pan so it spreads evenly.
8. Top with remaining oat mixture, pressing gently to sandwich the chocolate.
9. Chill for at least 30 minutes in the fridge—or pop it into the freezer for 15 if you’re impatient (we’ve all been there!).
10. Lift the set block out using the parchment overhang and slice into 12 bars (or 16 bite-sized squares).

Servings & Timing

Storage & Reheating

Store these bars in an airtight container in the fridge for up to 1 week—they stay perfectly chewy. For longer storage, freeze in a single layer between parchment sheets for up to 3 months. To thaw, transfer bars to the fridge for 30 minutes or let them sit at room temperature for 10 minutes. No reheating needed—just grab and go! For make-ahead planning, prep on Sunday evening and enjoy a guilt-free treat all week.

Notes

I learned that using natural peanut butter (the kind that separates) gives the best texture—you’ll need that coconut oil to help things bind. If your bars crumble a bit, press them extra firmly before chilling. For a fudgier bite, up the chocolate layer by 2 tbsp. And a quick hack: use a mandoline slicer for perfectly even oat layers if you’re feeling fancy. Finally, when it comes to sweetness, dark chocolate chips at 70% cacao are my personal favorite—they strike a lovely balance and make these bars taste more gourmet than they really are.

FAQs

• Q: Can I use quick-cooking oats instead of rolled oats?
A: Quick oats work in a pinch but can turn mushy—rolled oats give better chew.
• Q: Are these bars vegan?
A: Swap honey for maple syrup and you’re all set for a vegan-friendly version.
• Q: Why won’t my chocolate layer set?
A: Make sure your coconut oil is warm enough in the melt; too little oil can make the chocolate stiff and prone to cracking.
• Q: Can I add protein powder?
A: Absolutely—1/4 cup of unflavored protein powder blends nicely if you reduce the oats slightly.
• Q: How do I pack these for lunchboxes?
A: Wrap each bar in parchment or wax paper and tuck into an insulated lunch bag with an ice pack.
• Q: My mixture is too runny—what now?
A: Pop it in the fridge for 5–10 minutes, then stir; the coconut oil will firm up so you can press it.
• Q: Can I melt the chocolate in a double boiler instead?
A: Yes! A gentle double boiler is even safer—just keep water simmering, not boiling, below the bowl.
• Q: What’s the best way to cut clean bars?
A: Warm a sharp knife under hot water, dry it, then slice in one smooth pull.
