📋 Ingredient Checklist
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy or Crunchy Peanut Butter | 1 cup (240 g) | Use all-natural for a cleaner flavor |
| Coconut Oil (or neutral oil) | ¼ cup (60 mL) | Melted; sub avocado or canola oil if you like |
| Ripe Bananas, mashed | 2 large (≈1 cup / 240 g) | Look for lots of brown speckles for max sweetness |
| Maple Syrup (or honey) | ⅓ cup (80 mL) | Adjust to taste |
| Large Egg | 1 | For binding, swap with flax egg for vegan |
| Baking Powder | 1 teaspoon (4 g) | Gives a slight lift |
| Old‑Fashioned Rolled Oats | 3½ cups (280 g) | Quick oats risk a gummy texture |

🧑🍳 Step‑by‑Step Directions
Chef’s Tip: Measure your oats and peanut butter by weight if you can—it ensures perfect consistency every time.
- Preheat & Prep (5 min)
- Preheat your oven to 350°F (175 °C).
- Line a 9×13‑inch baking dish with parchment paper, leaving an overhang for easy removal.
- Lightly grease the paper with a thin swipe of coconut oil.
- Melt & Combine (3 min)
- In a large microwave‑safe bowl, combine peanut butter and coconut oil.
- Microwave on high for 20–30 seconds, or until both are just melted.
- Whisk vigorously until silky smooth.
- Build the Batter (2 min)
- Add mashed bananas, maple syrup, egg, and baking powder to the peanut butter mixture.
- Whisk until fully incorporated. The batter will thicken slightly.
- Incorporate the Oats (1 min)
- Stir in the old‑fashioned rolled oats until every flake is coated.
- Fold in the chocolate chips, reserving a small handful to press on top for visual appeal.
- Transfer & Bake (25 min)
- Pour the mixture into the prepared pan.
- Use an offset spatula or the back of a spoon to spread evenly and smooth the top.
- Sprinkle reserved chips over the surface.
- Bake for 20–25 minutes, until the edges are golden and the center is set but still soft.
- Cool & Slice (20 min)
- Allow the bars to cool completely in the pan on a wire rack—this helps them firm up.
- Use the parchment overhang to lift the slab out.
- Slice into 12–16 bars with a sharp knife, cleaning it between cuts for neat edges.
🔥 Pro Chef Tips
- Oats Quality Matters: Always choose old‑fashioned rolled oats over quick oats for that perfect chew and structure. Quick oats can turn your bars spongy.
- Banana Mash Mastery: Don’t just squish—use a fork to mash into a smooth puree. Small lumps are okay, but avoid big chunks that throw off the binding ratio.
- Sweetness Balance: If your bananas aren’t super sweet (a few speckles), add an extra tablespoon of maple syrup. Conversely, skip the chips or swap for unsweetened coconut flakes to lower sugar.
- Serving Temperature: These bars are heavenly warm—microwave a slice for 10 seconds before eating to get that melty chocolate and soft center.
- Make‑Ahead & Storage: Store airtight at room temperature for up to 3 days, or refrigerate for up to 1 week. Freeze individual bars for up to 3 months; thaw at room temp or zap in the microwave.

🤔 Five Frequently Asked Questions
1. Can I make these bars vegan?
Yes! Simply replace the egg with a “flax egg” (1 Tbsp flaxseed meal + 3 Tbsp water, whisked and rested 5 min). The texture remains just as tender and holds together beautifully.
2. Are these bars freezer‑friendly?
Absolutely. Store cooled, individually wrapped bars in a freezer‑safe bag for up to 3 months. Thaw at room temperature for 20 min or microwave for 15 sec.
3. What oil can I use instead of coconut oil?
Any neutral‑flavored oil works—avocado, canola, or light olive oil. Coconut oil adds a hint of tropical sweetness, but feel free to adapt.
4. How do I adjust the sweetness?
Taste-test your mashed bananas first. If they’re very ripe and sweet, you might reduce maple syrup by 1–2 Tbsp. For extra sweetness, stir in another tablespoon of syrup or a handful of mini chocolate chips.
5. Can I swap peanut butter for another nut or seed butter?
Yes—almond butter, cashew butter, or sunflower seed butter all work. Note that each has a distinct flavor and slightly different fat content, which can affect texture. If the batter seems too dry, add a teaspoon more oil or a splash of almond milk.
