The first cool Saturday of October always smells the same in my kitchen: butter browning on the stove, cinnamon in the air, and a bowl of apples waiting on the counter. That is the day these caramel apple blondies were born. I wanted the cozy flavor of apple pie without rolling a single crust, and I wanted the chewy, buttery bite of a good blondie. So I put the two together in one pan.
My first batch was a lesson. I tossed raw apple chunks straight into the batter, and the middle turned wet and gummy while the edges dried out. The fix was simple: dice the apples small, cook them for five minutes with a little cinnamon, and let them cool. Now every square has golden edges, a soft and chewy center, tender bits of apple, and a zig-zag of caramel on top. This guide walks you through every step, so your caramel apple blondies come out right on the first try.

Why These Caramel Apple Blondies Work
A blondie is a brownie without the chocolate. In caramel apple blondies, brown sugar and butter do most of the work, so they need to taste great. Here, three small choices make a big difference.
First, the butter is browned. Cooking it until the milk solids turn golden gives a nutty, toffee-like flavor that tastes like caramel before you even add the drizzle. Second, the apples are cooked before they go into the batter. Raw apples release water in the oven, and that water is what makes the center gummy. Third, the recipe uses one whole egg plus one extra yolk. The yolk adds richness and chew without making the bars cakey.
The result is a thick, soft bar, about 1 inch tall, that slices cleanly into 16 squares. If you love apple desserts, my apple cinnamon crumb cream cake is another fall favorite.
Ingredients for Caramel Apple Blondies
For the cinnamon apples
- 2 medium firm apples (about 12 oz or 340 g whole), such as Granny Smith or Honeycrisp.
- 1 tbsp (14 g) unsalted butter.
- 1 tbsp (13 g) packed light brown sugar.
- ½ tsp ground cinnamon and a pinch of salt.
For the brown butter blondie batter
- ¾ cup (170 g) unsalted butter.
- 1 cup (213 g) packed light brown sugar.
- ¼ cup (50 g) granulated sugar: it helps create the shiny, crackly top.
- 1 large egg plus 1 large egg yolk, at room temperature.
- 2 tsp vanilla extract.
- 1½ cups (180 g) all-purpose flour, spooned and leveled.
- 1 tsp ground cinnamon.
- ½ tsp baking powder.
- ½ tsp fine salt.
For the caramel drizzle
- ⅓ cup thick caramel sauce, homemade (see below) or store-bought.
Flour measured by the cup can vary a lot, and too much flour turns blondies dry and cakey. A simple digital scale fixes that. Bake these in a light-colored metal pan, like this USA Pan 9-inch square cake pan. Dark pans brown the edges too fast, and glass heats slowly, so the center stays raw while the corners overbake.
Choosing and Prepping the Apples
For caramel apple blondies, pick a firm apple that holds its shape. Soft varieties like McIntosh collapse into applesauce when heated. In a side-by-side baking test, King Arthur Baking found that Granny Smith apples keep their shape and balance sweet and tart flavor well. Honeycrisp is a sweeter option, and a mix of the two is lovely.
Peel the apples, then remove the cores. An OXO Good Grips apple corer pulls the core out in one twist. Dice the apples into small ¼ to ½-inch cubes. Bigger chunks make holes in the bars and leave pockets of raw batter around them.
Then cook the cubes in butter with brown sugar and cinnamon for 5 to 7 minutes. You want them just tender, with a knife sliding in easily, while the cubes still keep their edges. Let any juices bubble away until the pan looks almost dry. This step is the secret to a chewy center instead of a soggy one.
How to Brown Butter Without Burning It
Brown butter goes from perfect to burnt in about 30 seconds, so color is everything. Use a light-colored stainless pan, such as this Cuisinart Chef’s Classic 2-quart saucepan, so you can see the milk solids change. A dark nonstick pan hides the color until it is too late.
Melt the butter over medium heat and keep stirring. It will foam, crackle and sputter as the water cooks off. When the noise quiets down, watch closely. Small specks will form at the bottom and turn from tan to golden brown, and the kitchen will smell like toasted nuts. Pour it into a bowl right away, scraping in every brown bit, because the hot pan keeps cooking it. Serious Eats has a helpful visual guide to browning butter if this is your first time.
Browning drives off some water, which is fine here. The extra yolk brings back moisture and richness.
How to Make Caramel Apple Blondies Step by Step
1. Prepare the pan. Heat the oven to 350°F (175°C) with a rack in the middle. Grease a 9-inch square metal pan and line it with parchment, leaving a 2-inch overhang on two sides so you can lift the slab out later. Reynolds unbleached parchment paper folds neatly into the corners.
2. Brown the butter. Brown the ¾ cup of butter as described above, about 5 to 8 minutes. Pour it into a large heatproof bowl, add both sugars and whisk until smooth and glossy.
3. Cook the apples. In a skillet over medium heat, melt 1 tbsp butter, add the diced apples, brown sugar, cinnamon and salt, and cook for 5 to 7 minutes until just tender and the pan is nearly dry. Spread them on a plate to cool for 10 to 15 minutes.
4. Mix the batter. Once the butter mixture is warm but not hot, add the egg, yolk and vanilla. Whisk hard for 45 seconds, until thick and shiny. This helps the top bake up crinkly. Fold in the flour, cinnamon, baking powder and salt with a spatula until only a few dry streaks remain.
5. Fold in the apples. Add the cooled apples, leaving any liquid on the plate, and fold just until they are spread evenly through the thick batter.
6. Spread it out. Scrape the batter into the pan. It will be thick, so push it into the corners and level the top with an OXO Good Grips bent icing spatula.
7. Bake. Bake the caramel apple blondies for 32 to 38 minutes. The top should be golden brown and slightly crackly, the edges deeper golden and pulling away from the paper, and a toothpick in the center should come out with moist crumbs but no wet batter. If you like using a thermometer, an instant-read thermometer such as the TempPro TP19H should read at least 160°F in the center, the safe minimum the USDA recommends for dishes made with eggs.
8. Cool completely. Let the blondies cool in the pan on a wire rack for at least 2 hours. Warm blondies are still setting, and cutting them early gives you gooey, ragged squares.
9. Drizzle and slice. Warm the caramel until it flows from a spoon, then drizzle it back and forth in a zig-zag over the whole slab. Lift the slab out with the parchment and cut it into 4 rows by 4 rows for 16 squares, wiping the knife between cuts.
Homemade or Store-Bought Caramel?
Both work. A thick jarred caramel sauce is the shortcut. Warm it for 10 to 15 seconds in the microwave so it drizzles in thin lines instead of blobs.
For homemade caramel, put ½ cup (100 g) granulated sugar in a heavy saucepan over medium heat. Let it melt, swirling the pan, until it turns a deep amber color. Off the heat, whisk in 3 tbsp (42 g) butter, then slowly pour in ¼ cup (60 ml) warm heavy cream. It will bubble up hard, so stand back. Stir in ¼ tsp salt and ½ tsp vanilla. You will get about ⅔ cup. Use half for the blondies and save the rest for ice cream. For more on the science, read my guide on the best way to caramelize sugar.
Common Mistakes and How to Fix Them
- Gummy center: the apples were raw or too wet. Cook them first and let the pan get almost dry.
- Dry, cakey bars: too much flour, or the bars were overbaked. Weigh the flour and pull the pan out at moist crumbs.
- Bitter butter: the milk solids went from brown to black. Pour the butter out of the pan as soon as it smells nutty.
- Scrambled-looking batter: the butter was too hot when the eggs went in. Let it cool until warm to the touch.
- Messy squares: they were cut warm. Cool fully, or chill for 20 minutes before slicing.
How to Store and Freeze the Blondies
Because of the cooked fruit and caramel, keep caramel apple blondies covered at room temperature for up to 1 day, then move them to the refrigerator for up to 5 days. Bring them back to room temperature, or warm a square for 10 seconds in the microwave.
To freeze, wrap the squares individually and place them in a freezer bag for up to 3 months. Thaw them overnight in the fridge. Want more cozy treats to bake ahead? Try my two-ingredient apple cinnamon cookies or these brown butter rice crispy treats.

Caramel Apple Blondies
Chewy brown butter caramel apple blondies with tender cinnamon apple bites, crackly golden tops and a zig-zag caramel drizzle. Baked in a 9-inch square pan and cut into 16 squares.
- Total Time: 1 hour 15 minutes
- Yield: 16 squares
Ingredients
For the cinnamon apples:
2 medium firm apples (about 12 oz / 340 g whole), such as Granny Smith or Honeycrisp, peeled and cut into ¼–½ inch dice
1 tbsp (14 g) unsalted butter
1 tbsp (13 g) packed light brown sugar
½ tsp ground cinnamon
Pinch of salt
For the blondies:
¾ cup (170 g) unsalted butter
1 cup (213 g) packed light brown sugar
¼ cup (50 g) granulated sugar
1 large egg, room temperature
1 large egg yolk, room temperature
2 tsp vanilla extract
1½ cups (180 g) all-purpose flour, spooned and leveled
1 tsp ground cinnamon
½ tsp baking powder
½ tsp fine salt
For the topping:
⅓ cup thick caramel sauce, homemade (see Notes) or store-bought
Instructions
Heat the oven to 350°F (175°C) with a rack in the middle. Grease a 9-inch square metal pan and line it with parchment, leaving a 2-inch overhang on two sides.
Brown the butter: melt ¾ cup (170 g) butter in a light-colored saucepan over medium heat, stirring, for 5–8 minutes, until it stops sputtering, the milk solids turn golden brown and it smells nutty. Immediately pour it, with all the brown bits, into a large heatproof bowl.
Add the brown sugar and granulated sugar to the warm butter and whisk until smooth and glossy. Let cool while you cook the apples.
Cook the apples: melt 1 tbsp butter in a skillet over medium heat. Add the diced apples, 1 tbsp brown sugar, ½ tsp cinnamon and a pinch of salt. Cook, stirring, for 5–7 minutes, until just tender and the pan is nearly dry. Spread on a plate and cool for 10–15 minutes.
When the butter mixture is warm (not hot), add the egg, egg yolk and vanilla. Whisk vigorously for 45 seconds, until thick and shiny.
Add the flour, cinnamon, baking powder and salt. Fold with a spatula until only a few dry streaks remain.
Fold in the cooled apples, leaving any liquid behind, just until evenly distributed.
Spread the thick batter into the pan, pushing it into the corners, and smooth the top.
Bake for 32–38 minutes, until the top is golden and slightly crackly, the edges are deeper golden and a toothpick in the center comes out with moist crumbs (no wet batter). The center should read at least 160°F on an instant-read thermometer.
Cool completely in the pan on a wire rack, at least 2 hours.
Warm the caramel until it flows, then drizzle it in a zig-zag over the slab. Lift out with the parchment and cut 4 by 4 into 16 squares, wiping the knife between cuts.
Notes
Use a light-colored metal pan. Glass or dark pans overbake the edges before the center sets. In an 8-inch pan, bake 40–45 minutes.
Pre-cooking the apples is the key to a chewy (not gummy) center. Keep the dice small, ¼–½ inch.
Quick homemade caramel: melt ½ cup (100 g) granulated sugar in a heavy saucepan over medium heat, swirling, until deep amber. Off the heat, whisk in 3 tbsp (42 g) butter, then slowly add ¼ cup (60 ml) warm heavy cream (it bubbles up). Stir in ¼ tsp salt and ½ tsp vanilla. Makes about ⅔ cup; use half.
Store-bought caramel: choose a thick sauce and warm it 10–15 seconds so it drizzles in thin lines.
Cooling time (about 2 hours) is not included in Total Time. Chill 20 minutes for the cleanest cuts.
Storage: covered at room temperature up to 1 day, then refrigerated up to 5 days. Freeze individually wrapped squares up to 3 months; thaw overnight in the fridge.

Frequently Asked Questions
Can I make caramel apple blondies in an 8-inch pan?
Yes, but the bars will be thicker. Bake them for 40 to 45 minutes and check the center carefully. A 9×13 pan needs a doubled recipe.
Do I have to peel the apples?
No, but peeled apples give the soft, tender bite you see in the photos. Peel can turn chewy in the oven.
Can I add nuts?
Yes. Fold in ½ cup toasted chopped pecans with the apples. I keep these plain so the apple and caramel shine.
Why didn’t my blondies get a crackly top?
The sugar and eggs need that hard 45-second whisk. Granulated sugar helps too, so don’t swap it all for brown sugar.
Can I serve caramel apple blondies warm?
Absolutely. A warm square with a scoop of vanilla ice cream is pure fall comfort. For another apple and cream combo, try my apple cinnamon cheesecake crunch.
