Ingredients (Makes 9–12 Bars)
- ½ cup (1 stick / 113g) unsalted butter
- ½ cup packed brown sugar (or coconut sugar)
- ¼ cup honey or maple syrup
- ½ cup creamy peanut butter* (see note)
- 1 tsp vanilla extract
- 2 cups old-fashioned rolled oats (gluten-free if needed)
- 1 ½ cups semi-sweet chocolate chips
Peanut Butter Note: Use a classic, no-stir brand like Jif or Skippy. Natural peanut butter tends to separate and can prevent the bars from setting properly.
Step-by-Step Instructions
1. Prepare the Pan
Line an 8×8-inch baking dish with parchment paper, leaving a bit of overhang on two sides. This “sling” makes lifting and slicing a breeze.
2. Make the Base
In a medium saucepan, melt the butter, brown sugar, and honey over medium heat, stirring constantly until smooth. Let it reach a gentle boil, then immediately remove from heat. Stir in peanut butter and vanilla until creamy.
3. Mix in the Oats
Add oats to the saucepan and stir until fully coated.
4. Assemble the Layers
- Press half of the oat mixture firmly into the prepared pan—this forms the crust.
- Melt chocolate chips in 30-second bursts in the microwave, stirring in between, until smooth. Spread over the crust.
- Crumble and press the remaining oat mixture evenly on top of the chocolate.
5. Chill to Set
Refrigerate for 2–3 hours, or until the chocolate is firm. For quicker results, freeze for 30–45 minutes.
6. Slice and Serve
Lift the block out using the parchment sling and cut into squares. For neat cuts, wipe your knife with a warm, damp cloth between slices.
Pro Tips for Success
- Press Firmly: Compacting the oat layers ensures bars hold their shape.
- Don’t Over-Boil: Once the mixture bubbles, take it off the heat to avoid tough bars.
- Customize Mix-Ins: Try shredded coconut, nuts, or mini M&Ms for fun variations.
- Add a Chocolate Drizzle: Reserve a bit of melted chocolate to drizzle over the top for presentation.
- Choose the Right Pan: Light metal pans work best; glass dishes set more slowly.
Flavor Variations
- Almond Joy Bars: Use almond butter, stir in shredded coconut, and sprinkle sliced almonds on top.
- Double Chocolate: Add 2 tbsp cocoa powder to the oat mixture for extra chocolate punch.
- Salted Caramel: Drizzle caramel sauce over the chocolate layer before adding the top oats.
- Nut-Free Option: Replace peanut butter with sunflower seed butter for an allergy-friendly version.
FAQ
Q: Why are my bars crumbly?
A: They weren’t pressed firmly enough, or the sugar-butter mixture didn’t cook long enough.
Q: Can I use quick oats?
A: Yes, but the bars will be denser and less chewy. Rolled oats give the best texture.
Q: My bars won’t set—what went wrong?
A: Natural peanut butter is usually the culprit. Pop them in the freezer for an hour to firm up.
Q: Can I freeze them?
A: Absolutely! Wrap individual bars and freeze for up to 3 months. Thaw in the fridge or at room temperature.
