Maple syrup chords are a no-bake confection made by combining maple syrup with oats, nut butter, and melted chocolate, then chilling the mixture until firm. This version cuts the chilled slab into small, chewy squares with a sweet maple flavor and a little salt to balance it.
Ingredients
- ½ cup (120 ml) pure maple syrup
- ½ cup (128 g) creamy peanut butter, well stirred
- 1 teaspoon (5 ml) vanilla extract
- ¼ teaspoon fine salt
- 2 cups (180 g) old-fashioned rolled oats
- ½ cup (85 g) semisweet chocolate chips
- 1 teaspoon (5 ml) neutral oil, such as canola or avocado oil
- Flaky salt, optional, for topping
Instructions
- Line an 8-inch (20 cm) square pan with parchment paper, leaving enough overhang on two sides to lift the chilled mixture out. Measure the oats into a large bowl.
- Combine the maple syrup and peanut butter in a small saucepan. Warm over low heat for 2–3 minutes, stirring constantly, just until smooth and easy to mix. Do not let the mixture boil; boiling can make the maple mixture overly thick and difficult to spread. Remove from the heat and stir in the vanilla and fine salt.
- Pour the warm maple mixture over the oats. Stir thoroughly until the oats are evenly coated and no dry patches remain. Transfer the mixture to the lined pan and press it into an even, compact layer using the back of a spoon or a piece of parchment. Press firmly, especially into the corners, so the squares hold together after chilling.
- Put the chocolate chips and oil in a heatproof bowl. Microwave in 20-second bursts, stirring between each, until melted and smooth, usually 40–60 seconds in total. Alternatively, set the bowl over a pan of gently simmering water, making sure the bowl does not touch the water, and stir until melted.
- Spread the chocolate over the oat layer. If using, add a light sprinkle of flaky salt. Refrigerate uncovered for 60 minutes, or until the center feels firm and the chocolate has set. The total time includes this chilling period.
- Lift the slab out by the parchment and place it on a cutting board. Let it sit at room temperature for 3–5 minutes if the chocolate is very hard, then cut into 16 squares with a sharp knife. Wipe the blade between cuts for neater edges.
Tips
- Use pure maple syrup, not pancake syrup. Pancake syrup is usually made with other sweeteners and flavorings, so it gives a different taste and may make the mixture softer.
- Choose a creamy nut butter that is thick and well stirred. If yours is very runny, add another 2–3 tablespoons (15–22 g) oats so the mixture presses together instead of becoming greasy.
- For easier mixing, warm the maple syrup and nut butter only until they combine. A rolling boil is unnecessary and can reduce the moisture, making the finished squares dry or crumbly.
- Use parchment rather than greasing the pan. It makes the slab much easier to lift out, and firm, even pressing helps prevent loose pieces when slicing.
Serving Suggestions
Serve the squares chilled or let them stand at room temperature for about 5 minutes for a softer, chewier bite. They work well with coffee, tea, or a glass of cold milk, and make a handy small dessert after lunch. For a dessert plate, serve one or two squares with sliced apples or pears; their fresh, lightly tart flavor contrasts nicely with the sweet maple and chocolate.
These are rich, so cutting the slab into 16 small portions is practical. If you prefer a more substantial snack, cut it into 9 larger squares instead, keeping in mind that each piece will contain a larger share of the ingredients.
Variations
For a peanut-free version, use an equal amount of sunflower seed butter. The flavor will be earthier, and the mixture can be a little softer, so add extra oats a tablespoon at a time if needed. Almond butter also works, though it may make the squares less sweet and slightly firmer.
Replace up to ½ cup (45 g) of the oats with chopped toasted pecans, pumpkin seeds, or unsweetened shredded coconut. Keep the total dry ingredients close to the original amount so the bars still bind. For a different chocolate finish, use dark chocolate chips; white chocolate is sweeter and sets more softly, particularly in a warm room.
You can also skip the chocolate topping and fold ⅓ cup (55 g) mini chocolate chips into the oat mixture after it has cooled for a few minutes. This makes the bars simpler to slice and gives chocolate in each bite rather than a separate top layer.
Storage and Reheating
Store the squares in an airtight container in the refrigerator for up to 1 week. Place parchment between layers if stacking, to prevent the chocolate from sticking. As this is a no-bake mixture, it should not sit at room temperature for more than 2 hours; refrigerate leftovers promptly.
For longer storage, freeze the cut squares in a sealed freezer-safe container, with parchment between layers, for up to 2 months. Thaw in the refrigerator for several hours or briefly at room temperature. Reheating is not recommended: warmth softens the nut butter and can melt the chocolate topping.
Frequently Asked Questions
What are maple syrup chords?
Here, “maple syrup chords” refers to chilled, cut-up oat and nut-butter squares sweetened with maple syrup and topped with chocolate. The recipe is a no-bake treat rather than a baked cake or bread.
Can I use quick oats instead of rolled oats?
Yes, but quick oats absorb moisture differently and make the texture more compact and less chewy. Measure by weight if possible, and check that the mixture presses together before transferring it to the pan.
Can I make these without peanut butter?
Yes. Substitute the same quantity of sunflower seed butter or almond butter. A different nut or seed butter can change the flavor and firmness, so adjust with a little extra oats if the mixture looks loose.
Why are my squares crumbly?
The mixture may not have been pressed firmly enough, or it may have too many dry ingredients for the amount of syrup and nut butter. Press it tightly into the pan before chilling; if it still seems dry in the bowl, stir in another teaspoon of maple syrup at a time.
Can I make the recipe ahead?
Yes. Prepare and chill the slab, then cut it once fully firm. Keep the squares covered in the refrigerator for up to 1 week, or freeze them for up to 2 months.
Do I need to cook the oats?
No. Rolled oats are ready to eat, and the warm syrup and nut-butter mixture is used to bind them rather than cook them. The brief heating step should be gentle; it is not necessary to boil the syrup.
