Ingredients
Method
Reduce the Apple Cider & Brown the Butter
- In a small saucepan over medium heat, bring 1 1/2 cups of pure spiced apple cider to a gentle boil. Simmer uncovered for 15 to 18 minutes, swirling occasionally, until reduced down to exactly 1/3 cup of intensely fragrant, amber syrup. Let cool slightly.
- In a separate light-colored skillet or saucepan, melt 3/4 cup unsalted butter over medium heat. Swirl constantly as it foams and sizzles. Once golden-brown flecks form on the bottom and a nutty aroma fills the kitchen (about 4 to 5 minutes), immediately pour into a heatproof bowl to stop cooking.
Whisk the Chewy Batter
- Preheat oven to 350°F (175°C). Line an 8x8-inch metal baking pan with parchment paper, leaving an overhang on the sides for easy lifting.
- In a large bowl, whisk the warm brown butter, brown sugar, and granulated sugar together until smooth. Whisk in the eggs one at a time, followed by the cooled 1/3 cup apple cider reduction and vanilla extract. Whisk vigorously for 1 minute until glossy.
- Add the all-purpose flour, ground cinnamon, nutmeg, allspice, baking powder, and sea salt. Fold gently with a silicone spatula just until no flour streaks remain (do not overmix).
Bake to Fudgy Perfection
- Spread the thick, luscious batter evenly into the prepared baking pan, smoothing the surface with an offset spatula.
- Bake at 350°F (175°C) for 22 to 26 minutes until edges are golden and lightly pulling away from the parchment, and a toothpick inserted into the center comes out with a few moist, fudgy crumbs (avoid overbaking to preserve ultra-chewy texture).
- Transfer pan to a wire rack and allow blondies to cool completely to room temperature before glazing.
Glaze, Slice & Serve
- In a small bowl, whisk together the sifted powdered sugar, pure maple syrup, and melted butter until smooth and pourable.
- Lift blondies out of the pan using parchment handles. Pour the salted maple glaze over the top, letting it cascade down the sides. Sprinkle generously with flaky Maldon sea salt and a pinch of ground cinnamon.
- Allow glaze to set for 15 minutes, then slice into 16 thick squares with a sharp chef knife. Enjoy with a warm cup of coffee or spiced apple cider!
