These Brown Butter Apple Cider Blondies are soft, chewy fall dessert bars made with nutty brown butter, reduced apple cider, cinnamon, brown sugar, and tiny pieces of fresh apple.

They have crisp golden edges, a soft center, and deep caramel-apple flavor without needing frosting or a complicated topping.

Easy Apple Cider Blondies

Apple cider adds a really nice fall flavor to blondies, but using it straight from the jug can make the batter too wet.

That’s why this recipe starts by reducing the cider on the stovetop until it becomes more concentrated.

Brown butter gives the bars extra depth, while cinnamon and brown sugar make them taste warm and cozy without turning them into spice cake.

The diced apple adds little pockets of soft fruit throughout the blondies.

🛒 Ingredients

Apple Cider

Use real apple cider, not apple juice.

Reducing it first intensifies the flavor.

Unsalted Butter

The butter is browned for a deeper nutty flavor.

Brown Sugar

Adds sweetness and a caramel-like flavor.

Granulated Sugar

Helps balance the texture.

Eggs

Give the blondies structure and chewiness.

Vanilla Extract

Adds warmth.

All-Purpose Flour

Provides structure without making the bars cakey.

Cinnamon

The main spice.

Salt

Balances the sweetness and enhances the brown butter.

Fresh Apple

Dice it very finely so it softens while baking.

Honeycrisp, Gala, Fuji, or Pink Lady all work well.

👩‍🍳 How to Make Brown Butter Apple Cider Blondies

1. Reduce the Apple Cider

Pour the apple cider into a small saucepan.

Bring it to a gentle simmer over medium heat.

Cook until reduced to approximately ¼ cup.

This may take around 15–20 minutes.

Set aside to cool slightly.

2. Brown the Butter

Place the butter in a light-colored saucepan over medium heat.

Let it melt, then continue cooking while stirring frequently.

The butter will foam, then the milk solids will begin to turn golden brown.

Once it smells nutty and you see amber-brown bits at the bottom, remove it from the heat immediately.

3. Cool Slightly

Let the browned butter cool for about 10 minutes.

4. Prepare the Pan

Preheat the oven to 350°F (175°C).

Line an 8 × 8-inch baking pan with parchment paper.

5. Mix the Wet Ingredients

In a large bowl, whisk together:

• Brown butter
• Brown sugar
• Granulated sugar
• Eggs
• Vanilla
• Reduced apple cider

Whisk until smooth and glossy.

6. Add the Dry Ingredients

Add:

• Flour
• Cinnamon
• Salt

Fold gently until just combined.

7. Add the Apple

Fold in the finely diced apple.

Make sure the pieces are distributed evenly.

8. Spread the Batter

Transfer the batter to the prepared pan.

Spread it evenly toward the corners.

9. Bake

Bake for approximately 28–34 minutes.

The edges should be golden and set.

The center should look baked but still slightly soft.

A toothpick should come out with a few moist crumbs, not wet batter.

10. Cool Completely

Let the blondies cool completely in the pan.

This helps the center set and makes slicing easier.

11. Slice

Lift the blondies out using the parchment paper.

Cut into squares.

✨ Variations

Apple Cinnamon Blondies

Increase the cinnamon slightly and skip the cider reduction if needed.

Pecan Apple Cider Blondies

Fold in chopped toasted pecans.

White Chocolate Apple Blondies

Add white chocolate chips.

Maple Apple Blondies

Replace part of the granulated sugar with a little maple sugar or add maple extract.

Salted Brown Butter Blondies

Finish with a very light pinch of flaky salt after baking.

🔥 Tips for the Best Blondies

Reduce the cider. This is the key to strong apple flavor without watery batter.

Use a light-colored pan for browning butter. It’s easier to see the milk solids changing color.

Don’t burn the butter. Once the brown bits appear, remove it from the heat.

Dice the apple very small. Large pieces can make the bars too wet.

Don’t overmix the batter. Fold just until combined.

Don’t overbake. Blondies should stay soft in the center.

Cool before slicing. Warm blondies are much more fragile.

🥡 Storage

Room Temperature

Store in an airtight container for up to 2 days.

Refrigerator

For longer storage, refrigerate for up to 5 days.

Freezer

Wrap individual blondies and freeze for up to 2 months.

Serving

Let chilled blondies sit at room temperature for a few minutes for the best texture.
