They are the epitome of “cozy baking,” filling your kitchen with the warm scents of cinnamon and caramelized sugar.

What makes these blondies truly special is their versatility.

The addition of flaky sea salt cuts through the sweetness, creating a perfectly balanced flavor profile that will have everyone reaching for seconds. Whether you’re a seasoned baker or just looking to try something new this fall, this recipe is guaranteed to become a seasonal favorite.

Ingredients

For the Blondies:

1 cup (2 sticks) unsalted butter, melted and slightly cooled
1 ½ cups packed dark brown sugar
½ cup granulated sugar
2 large eggs, at room temperature
1 tablespoon vanilla extract
1 cup apple butter, store-bought or homemade
2 cups all-purpose flour
1 teaspoon baking powder
½ teaspoon fine sea salt
1 teaspoon ground cinnamon
¼ teaspoon ground nutmeg

For the Salted Caramel Topping:

1 cup granulated sugar
6 tablespoons unsalted butter, cut into cubes
½ cup heavy cream, at room temperature
1 teaspoon flaky sea salt (such as Maldon), plus more for sprinkling

Instructions

1. Prepare the Pan:

Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an “overhang” on the sides to act as handles. This will make removing the finished blondies much easier. Lightly grease the parchment paper with cooking spray or butter.

2. Mix the Wet Ingredients:

In a large bowl, combine the melted butter, dark brown sugar, and granulated sugar. Whisk vigorously for 1-2 minutes until the mixture is smooth and the sugar is slightly dissolved. Add the eggs and vanilla extract, and whisk again until fully incorporated. Finally, whisk in the apple butter until the batter is uniform in color and texture.

3. Combine Dry Ingredients:

In a separate medium bowl, whisk together the all-purpose flour, baking powder, fine sea salt, cinnamon, and nutmeg.

4. Make the Blondie Batter:

Pour the dry ingredients into the wet ingredients. Use a rubber spatula to gently fold the mixture together until just combined. Be careful not to overmix, as this will result in tough, cakey blondies. A few streaks of flour are perfectly fine.

5. Bake:

Pour the batter into the prepared 9×13 inch pan and spread it into an even layer using your spatula. Bake in the preheated oven for 30-35 minutes, or until the edges are set and golden brown, and a wooden skewer inserted into the center comes out with a few moist crumbs. Do not overbake!

6. Cool:

Place the pan on a wire rack and let the blondies cool completely in the pan.

7. Make the Salted Caramel:

While the blondies are cooling, make the caramel. Pour the 1 cup of granulated sugar into a medium, heavy-bottomed saucepan. Place it over medium heat. Watch the sugar carefully as it begins to melt around the edges. Once melting starts, you can gently swirl the pan to incorporate the unmelted sugar, but avoid stirring with a utensil at this stage, as it can cause crystallization. Continue to cook until all the sugar has melted and turned a deep, amber-brown color. Immediately remove the pan from the heat.

Slowly and carefully whisk in the cubed butter (the mixture will bubble vigorously, so be cautious). Once the butter is fully melted, slowly stream in the heavy cream while whisking constantly until the caramel is smooth and uniform. Whisk in the 1 teaspoon of flaky sea salt. Let the caramel cool for about 10-15 minutes so it thickens slightly.

8. Assemble and Serve:

Once the blondies are completely cool, use the parchment paper overhangs to lift the entire slab out of the pan and onto a cutting board. Pour or drizzle the slightly cooled salted caramel sauce over the top of the blondies. You can spread it evenly or leave it in dramatic drizzles. Sprinkle with an additional generous pinch of flaky sea salt.

Allow the caramel to set for at least 15 minutes before slicing into squares. For perfectly clean cuts, you can chill the slab in the refrigerator for 30 minutes before slicing with a sharp knife, wiping the blade clean between each cut.

Tips for Success

Measure Flour Correctly: Spoon the flour into your measuring cup and level it off with a knife, rather than scooping directly from the bag. Scooping packs the flour, which can lead to dry, dense blondies.
Don’t Overbake: The key to a fudgy, gooey blondie is taking it out of the oven while it still looks slightly underdone in the center. It will continue to set as it cools.
Temperature Matters: Ensure your eggs and heavy cream are at room temperature. If cold ingredients are added to the warm caramel or butter-sugar mixture, it can cause the mixture to seize or the butter to re-solidify.
Safety First: Making caramel can be dangerous due to the high heat of the melted sugar. Always use a heavy-bottomed pan, stand back when adding the butter and cream, and never leave the stove unattended.

Storage and Reheating

Storage: Store the blondies in an airtight container at room temperature for up to 4 days, or in the refrigerator for up to 7 days. Keep them separated by parchment paper to prevent sticking.
Reheating: For that fresh-baked experience, microwave a single blondie for 15-20 seconds until the caramel is gooey and the blondie is warm.
Freezing: The uncut slab (without caramel) can be wrapped tightly in plastic wrap and aluminum foil and frozen for up to 3 months. Thaw overnight in the refrigerator before adding the caramel topping and slicing.

Serving Suggestions

à la Mode: Serve a warmed blondie with a scoop of vanilla bean ice cream and an extra drizzle of warm salted caramel.
Coffee Companion: The rich, spiced flavor makes these the perfect accompaniment to a hot cup of coffee, an apple cider latte, or a spiced chai.
Dessert Board: Cut the blondies into smaller bite-sized pieces and add them to an autumnal dessert board alongside apple slices, caramel dip, and pretzels.
