Caramel Apple Blondies: The Fall Treat I Didn’t Know I Needed

Caramel Apple Blondies: I wasn’t planning on making these. I had apples going soft on my counter, a random craving for something buttery, and zero patience for a full pie crust. So these blondies happened almost by accident.

And now I make them every single week once September hits.

They’re chewy. They’re loaded with cinnamon-spiced apple. And there’s a salted caramel drizzle on top that makes people ask what bakery I bought them from.

Side Note: if you’ve made my pumpkin bread before, this is basically its cooler, chewier cousin.

Here’s everything you need to make them.

  • Rubber spatula
  • Small saucepan (only if making caramel from scratch)

Pro Tips

Blondies look simple, but a few small details separate the good ones from the great ones.

  1. Dice the apple small. Big chunks release too much moisture while baking and you end up with a soggy middle. Small dice, evenly spread, is the move.
  2. Don’t overbake. Pull them when the center still looks slightly underdone. They firm up as they cool, and overbaked blondies turn cakey instead of chewy.
  3. Let them cool before slicing. I know it’s hard. But cutting into warm blondies means they fall apart everywhere.
  4. Room temperature eggs matter here. Cold eggs seize the melted butter and you get a lumpy, uneven batter.
  5. Line your pan with parchment and leave an overhang. You can lift the whole block out in one piece instead of fighting it with a spatula.

How to Make Caramel Apple Blondies

  1. Preheat your oven to 350°F. Line a 9×9 baking pan with parchment paper, leaving a little overhang on two sides.
  2. In a large bowl, whisk together the melted butter and brown sugar until smooth.
  3. Add the eggs one at a time, whisking well after each addition. Stir in the vanilla.
  4. In a separate bowl, combine the flour, baking powder, cinnamon, and salt.
  5. Add the dry ingredients to the wet ingredients. Stir just until combined. Don’t overmix, or the blondies turn tough.
  6. Fold in the diced apple gently.
  7. Pour the batter into your prepared pan and spread it evenly.
  8. Bake for 30 to 35 minutes, until the top is golden and a toothpick comes out with a few moist crumbs (not wet batter).
  9. Let the blondies cool in the pan for at least 20 minutes.
  10. Drizzle warm caramel sauce over the top and finish with a pinch of flaky sea salt.
  11. Slice into squares and try not to eat three before anyone else gets one.

Substitutions and Variations

Caramel Apple Blondies: The Fall Treat I Didn’t Know I Needed
Original Swap Notes
All-purpose flour 1:1 gluten-free flour blend Texture stays close to the original
Brown sugar Coconut sugar Slightly less sweet, deeper flavor
Honeycrisp apple Granny Smith More tart, holds shape better
Caramel sauce Butterscotch sauce Different but equally addictive
Butter Melted coconut oil Works, but loses some richness

Want a fall spice bomb? Add 1/4 teaspoon of nutmeg and a pinch of ground cloves along with the cinnamon.

Want them extra gooey? Swirl half the caramel into the batter before baking, then drizzle the rest on top.

Make Ahead Tips

You can make the batter up to a day ahead and store it covered in the fridge. Let it sit at room temperature for 15 minutes before baking, since cold batter needs a few extra minutes in the oven.

The diced apple can also be prepped a day early. Just toss it with a little lemon juice so it doesn’t brown.

A Few Extra Details

Nutritional snapshot (per blondie, makes 16): Roughly 220 calories, 9g fat, 32g carbs, 2g protein. This will vary slightly depending on your caramel sauce.

Dietary swaps: For a dairy-free version, use plant-based butter and a dairy-free caramel. Most grocery stores carry one now, and honestly you can’t tell the difference.

Pairing suggestions: These are incredible with a scoop of vanilla ice cream while still slightly warm. For drinks, a chai latte or plain black coffee cuts through the sweetness nicely.

Time-saving tip: Melt your butter in the microwave instead of on the stove. It saves about five minutes and one extra dish to wash.

Leftovers and Storage

Store blondies in an airtight container at room temperature for up to 3 days.

For longer storage, keep them in the fridge for up to a week. The caramel firms up a bit when chilled, so let them sit out for 10 minutes before eating.

Freezing: wrap individual squares in plastic wrap, then store in a freezer bag for up to 3 months. Thaw at room temperature or microwave for 15 seconds.

FAQ Related to Caramel Apple Blondies

1. Can I use canned apple pie filling instead of fresh apple?

You can, but drain it well first. Too much liquid will make the blondies dense.

2. Why are my blondies falling apart?

They probably needed more cooling time. Blondies set as they cool, so give them a full 20 minutes minimum before slicing.

3. Can I double this recipe?

Yes. Use a 9×13 pan and add about 5 to 8 extra minutes of bake time.

4. Do I have to peel the apple?

No, but the peel adds a slightly chewy texture that some people don’t love in a soft blondie. Your call.

5. Can I make these without caramel?

Absolutely. A dusting of powdered sugar or a simple cinnamon glaze works just as well.

Conclusion

These blondies became one of those recipes I keep coming back to without even meaning to. They’re easy enough for a random Tuesday and impressive enough that people ask for the recipe. That combination is rare, and I’ll take it every time fall rolls around.

If you try these, I’d genuinely love to know how they turned out for you. Drop a comment below and let me know if you made any swaps, and if you have questions about the recipe, ask away. I read every single one.
