Why You'll Love This Recipe
About the Ingredients
2 cups (200g) old-fashioned rolled oats
Use old-fashioned oats for the best chew; quick oats will make a softer bar. For a gluten-free version, use certified gluten-free oats.
1/2 cup (128g) creamy peanut butter
Natural peanut butter works, but make sure it's well-stirred. Almond butter or sunflower seed butter are great alternatives.
1/2 cup (170g) honey or maple syrup
Honey gives a classic flavor, but maple syrup adds a subtle smokiness. For a vegan option, use maple syrup.
1/4 cup (56g) unsalted butter, melted
Coconut oil is a great dairy-free substitute. Use refined coconut oil to avoid a coconut taste.
1/2 cup (100g) semi-sweet chocolate chips
Dark chocolate chips add a richer flavor. You can also use white chocolate or butterscotch chips.
1/4 cup (30g) chopped peanuts or almonds
For extra crunch, add toasted nuts. If you're nut-free, use sunflower seeds or omit.
1 teaspoon vanilla extract
Pure vanilla extract enhances the flavor; imitation works too.
1/4 teaspoon salt
Salt balances the sweetness. If using salted peanut butter, reduce to a pinch.
Tips & Tricks
- Line your pan with parchment paper for easy removal.
- Press the mixture firmly into the pan to prevent crumbling.
- Chill for at least 2 hours; the bars will set better.
- Use a sharp knife to cut clean slices; wipe the knife between cuts.
Pro Tips
Step-by-Step Instructions
1. Line the pan
Line an 8×8-inch (20×20 cm) baking dish with parchment paper, leaving overhang on two sides for easy lifting.
2. Mix dry ingredients
In a large bowl, combine the oats, chocolate chips, chopped nuts, and salt. Stir to distribute evenly.
3. Warm wet ingredients
In a small saucepan over low heat, melt the peanut butter, honey, and butter together, stirring until smooth. Remove from heat and stir in vanilla. Do not boil; just warm until combined.
4. Combine mixtures
Pour the wet mixture over the dry ingredients and stir with a spatula until everything is evenly coated. The mixture will be thick and sticky.
5. Press into pan
Transfer the mixture to the prepared pan and press it down firmly using a spatula or your hands. Make sure the top is even and compact.
6. Chill to set
Refrigerate for at least 2 hours, or until firm. This allows the bars to hold their shape when cut.
7. Cut and serve
Lift the bars out using the parchment, place on a cutting board, and cut into 12 squares. Serve cold or at room temperature.
Delicious Variations
- Add 1/2 cup dried cranberries or raisins for a fruity twist.
- Swap chocolate chips for white chocolate and add dried apricots.
- Top with a layer of melted chocolate and sprinkle with sea salt before chilling.
