Ingredients
• 1½ cups old-fashioned rolled oats (gluten-free if needed)
• ½ cup creamy peanut butter (natural, no-stir variety)
• ¼ cup pure maple syrup (or honey for extra depth)
• 2 tablespoons ground flaxseed (or chia seeds)
• ½ teaspoon pure vanilla extract
• Pinch of fine sea salt
• ½ cup dark chocolate chips (70% cacao recommended)
• 1 teaspoon coconut oil (to melt chocolate smoothly)
(Tip: Use whole-grain oats for chewiness; I like Bob’s Red Mill. Natural peanut butter lends a cleaner flavor.)
Directions
1. Line an 8×8-inch baking pan with parchment paper. This simple trick makes slicing so much easier—trust me.
2. In a medium bowl, stir together oats, ground flaxseed, and salt until evenly combined.
3. Warm peanut butter and maple syrup in a small saucepan over low heat, stirring until glossy; remove from heat and stir in vanilla.
4. Pour the warm peanut butter mixture over the oat blend. Use a silicone spatula to fold gently, ensuring every oat is coated.
5. Transfer the oat-peanut butter mix into the prepared pan. Press down firmly with the back of a spoon—or clean hands—so the layer is even.
6. Pop the pan in the fridge for 15–20 minutes while you prep the chocolate layer.
7. Melt dark chocolate chips and coconut oil in a double boiler or microwave (20-second bursts, stirring between). Aim for a smooth, pourable consistency.
8. Pour the melted chocolate over the chilled oat base. Tilt the pan to spread evenly, creating a glossy top.
9. Return to the fridge for at least 30 minutes, or until the chocolate is fully set. (You can cover loosely with plastic wrap to avoid fridge smells.)
10. Lift the parchment out, slice into 12 bars, and enjoy!
Servings & Timing
Yield: Makes 12 bars
Prep Time: 10 minutes (plus heating chocolate)
Chill Time: 30 minutes (plus optional overnight rest)
Total Time: Approximately 40 minutes
Variations
• Swap peanut butter for almond or cashew butter for a different nut-butter twist.
• Stir in 2 tablespoons mini white chocolate chips for a marbled look.
• Add 2 tablespoons shredded coconut to the oat layer for tropical flair.
• Mix in ¼ cup dried cranberries or raisins during step 2 for extra chew.
• Use sunflower seed butter for a nut-free version that’s perfect for school snacks.
Storage & Reheating
Store bars in an airtight container in the fridge for up to 7 days. For longer keeping, freeze individually wrapped bars for up to 1 month. Thaw in the fridge or at room temperature for 20 minutes—no reheating needed, though a 5-second zap in the microwave brings back that just-made softness. Make-ahead? Absolutely: assemble today, chill overnight, and slice fresh tomorrow morning.
Notes
• I learned that pressing the oat layer firmly prevents crumbs and gives bars a professional edge—no one wants a crumbling snack!
• If your peanut butter has separated, give it a good stir before measuring; it melts more evenly that way.
• Coconut oil isn’t strictly necessary, but it helps the chocolate top harden with a glossy sheen.
• For a lighter bite, halve the chocolate layer or use dark cacao nibs on top.
• These bars adapt beautifully—tweak sweeteners or nut butters based on what’s in your pantry.
FAQs
Q: Can I use quick oats instead of rolled oats?
A: Quick oats will work, but you’ll lose some chewiness—rolled oats give the best texture.
Q: Is honey okay instead of maple syrup?
A: Yes, honey adds a floral note; just gently warm to make sure it blends well.
Q: How do I keep the bars from sticking?
A: Parchment paper is your friend—line the pan fully and lift out the set bars.
Q: Can I skip the chocolate layer?
A: Sure! The peanut-oat base is tasty on its own—just chill and slice.
Q: Are these bars kid-friendly?
A: Definitely—they’re sweet without refined sugar and small enough for little hands.
Q: What if my chocolate seizes?
A: Stir in a teaspoon of coconut oil or a splash of warm milk to smooth it out.
Q: Can I halve or double the recipe easily?
A: Yes—just adjust pan size (a loaf pan for half, a 9×13 for double) and chill times.
