Maple Walnut Blondies
Blondies are the brownies’ golden, butterscotch-kissed cousins — and these maple walnut blondies might be the best version I have ever made. Imagine a bar with crackly, caramelized edges, a dense and chewy center that tastes like brown butter and maple syrup, and toasted walnuts adding crunch in every single bite. They are the kind of treat that disappears from the cooling rack before you have even cut them properly.
What sets this recipe apart is the double hit of maple: pure maple syrup in the batter plus a touch of maple extract to make the flavor unmistakable. Brown sugar brings the butterscotch depth, melted butter keeps everything rich and chewy, and toasting the walnuts first — a small step with a big payoff — makes them taste almost candied against the sweet batter.
Best of all, this is a true one-bowl wonder: no mixer, no creaming, no fuss. Whisk, fold, bake, and try to wait until they cool. (Good luck with that last part.)

- Perfect for fall — tastes like a crisp October afternoon.
Ingredients
- 1 cup (225 g) unsalted butter, melted and slightly cooled
- 1 1/2 cups (300 g) packed light brown sugar
- 1/3 cup (80 ml) pure maple syrup
- 2 large eggs, room temperature
- 1 tablespoon (15 ml) pure vanilla extract
- 1/2 teaspoon maple extract (optional, but recommended)
- 2 cups (250 g) all-purpose flour
- 1 teaspoon baking powder
- 3/4 teaspoon fine sea salt
- 1 1/2 cups (180 g) chopped walnuts, toasted
- Flaky sea salt, for sprinkling (optional)
Instructions
- Prep the pan and oven. Preheat the oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving overhang on two sides for easy lifting.
- Toast the walnuts. Spread the chopped walnuts on a small baking sheet and toast in the preheating oven for 6 to 8 minutes, until fragrant and lightly golden. Watch them closely — nuts go from toasted to burnt fast. Set aside to cool.
- Whisk the base. In a large bowl, whisk the melted butter, brown sugar, and maple syrup until smooth, glossy, and well combined, about 1 minute. The mixture should look like caramel sauce.
- Add eggs and flavorings. Whisk in the eggs one at a time until each is fully incorporated, then whisk in the vanilla extract and maple extract (if using). The batter will be thick and shiny.
- Fold in the dry ingredients. Sprinkle the flour, baking powder, and salt over the batter and fold gently with a spatula just until no dry streaks remain. Do not overmix — a few small lumps are fine.
- Add the walnuts. Fold in the toasted walnuts, reserving a small handful. Spread the batter evenly in the prepared pan with the spatula, then press the reserved walnuts into the top. Sprinkle with flaky sea salt if you like that sweet-salty contrast.
- Bake. Bake for 26 to 30 minutes, until the top is golden and crackled, the edges are set and pulling slightly from the pan, and a toothpick inserted in the center comes out with moist crumbs clinging to it — not wet batter. Err on the side of underbaking for maximum chew.
- Cool and cut. Cool completely in the pan on a wire rack, at least 1 hour — the centers finish setting as they cool. Lift out using the parchment overhang and cut into 16 squares with a sharp knife.
Tips for success
- Use pure maple syrup. Pancake syrup is mostly corn syrup with maple flavoring — it won’t give you the real deal. Grade A dark/robust has the strongest flavor for baking.
- Don’t overbake. This is the golden rule of blondies. Moist crumbs on the toothpick mean chewy; a clean toothpick means cakey.
- Cool fully before cutting. Warm blondies are delicious but fragile — they slice cleanly only once completely cool.
- Toast the walnuts. Raw walnuts taste flat and slightly bitter next to all that sweetness; toasting transforms them.
- Measure flour correctly. Spoon it into the cup and level it off — packed flour makes dense, dry bars.
Variations
- Maple pecan blondies: swap the walnuts for toasted pecans — a natural pairing with maple.
- White chocolate maple blondies: fold in 1 cup (175 g) of white chocolate chips with the walnuts.
- Browned butter blondies: brown the butter in a saucepan until nutty and amber, then cool slightly before using — incredible depth.
- Apple maple blondies: fold in 1 cup (120 g) of finely diced apple tossed in cinnamon for a fall orchard twist.
- Gluten-free: use a 1:1 gluten-free baking flour blend; the texture stays wonderfully chewy.
Storage and make-ahead
Blondies are excellent keepers. Store them in an airtight container at room temperature for up to 4 days — they stay chewy and the maple flavor deepens. In the refrigerator they last up to a week; bring to room temperature (or warm for 10 seconds in the microwave) before serving.
They freeze beautifully for up to 3 months: wrap individual squares in plastic wrap, bag them up, and thaw at room temperature. The batter can also be mixed a day ahead and refrigerated; let it sit at room temperature for 20 minutes before baking.
Frequently asked questions
What’s the difference between blondies and brownies?
Brownies get their flavor from chocolate or cocoa; blondies get theirs from brown sugar, butter, and vanilla (or in this case, maple) — think butterscotch versus chocolate.
Can I skip the maple extract?
Yes — the bars will still taste wonderfully of maple from the syrup alone. The extract just amplifies it, so add it if you have it.
Why are my blondies cakey instead of chewy?
Overbaking and too much flour are the two culprits. Pull them when the toothpick shows moist crumbs, and measure your flour with the spoon-and-level method.
Can I double the recipe?
Absolutely — bake in a 9×13-inch (23×33 cm) pan for 30 to 35 minutes. Everything else stays the same.
