Sharing is caring!

If you’re looking for the ultimate dessert bar that hits every note—sweet, salty, buttery, and bold—these Brown Butter Salted Caramel Espresso Bars are it. Imagine the nutty aroma of brown butter fused with the rich bitterness of espresso, layered with gooey salted caramel and tucked into a chewy, golden base. This dessert isn’t just a bar; it’s an experience. Whether you’re a coffee lover or a caramel fanatic, this will be your new go-to treat. These bars are crafted to impress but easy enough to make on a lazy Sunday afternoon. And they store beautifully, making them a perfect make-ahead option for gatherings, gifts, or a well-earned indulgence at home.

The inspiration for this recipe came from the desire to elevate classic blondies by weaving in more complex flavors. Brown butter deepens the taste, adding a toasty, almost nutty character. The salted caramel brings in that luscious, sweet-salty contrast, while espresso cuts through with a sharp, aromatic bitterness that balances everything out. It’s layered but not complicated. You won’t need any fancy equipment or hard-to-find ingredients—just a few pantry staples, some patience with the browning butter, and a good whisk.

For anyone who enjoys the chewy edge of a cookie or the richness of a caramel macchiato, this is your dessert. You can cut them into small squares for bite-sized indulgence or go big with generous bars. They travel well, freeze well, and taste incredible either chilled or slightly warmed. Plus, they look amazing when topped with a light drizzle of caramel and a pinch of flaky sea salt.

We tested this recipe multiple times to find the ideal balance of texture and flavor. The bar base is buttery and tender with a crisp edge. The middle layer—that golden salted caramel—is the heart of the bar, soaking slightly into the base to create an almost fudge-like texture. The espresso enhances the complexity, adding depth without overpowering the sweetness.

This recipe is a crowd-pleaser for any coffee hour, potluck, or holiday tray. You can easily customize it—add chopped nuts for crunch, swap the espresso for decaf, or use dark chocolate chunks for extra richness. No matter how you tweak it, the core flavors hold up beautifully.

Serve these with a glass of milk, a hot espresso, or even a scoop of vanilla ice cream. The contrast in temperatures and textures makes it a memorable dessert. And because the flavor profile is bold but balanced, it appeals to both adults and kids alike.

There’s something nostalgic and comforting about caramel and coffee, especially when wrapped in the warmth of browned butter. This bar captures that sentiment in every bite. You might start making it for others, but you’ll keep coming back to it for yourself.

Servings: 16 bars
Prep Time: 20 minutes
Cook Time: 35 minutes
Cooling Time: 1 hour
Total Time: 1 hour 55 minutes

Ingredients:

For the bar base:

• 1 cup (2 sticks) unsalted butter
• 1 1/2 cups light brown sugar, packed
• 2 large eggs
• 2 tsp vanilla extract
• 2 tbsp instant espresso powder
• 1/2 tsp salt
• 1 3/4 cups all-purpose flour

For the caramel layer:

• 1 cup granulated sugar
• 6 tbsp unsalted butter, cut into cubes
• 1/2 cup heavy cream
• 1/2 tsp sea salt (plus more for topping)

Instructions:

1. Brown the Butter: In a medium saucepan over medium heat, melt the butter and continue to cook until golden brown and fragrant, about 5–7 minutes. Let cool for 5 minutes.
2. Make the Base: In a large bowl, whisk together the browned butter and brown sugar. Add eggs and vanilla, whisking until smooth. Stir in espresso powder and salt. Fold in the flour just until combined. Spread the mixture into a greased or parchment-lined 9×13 inch pan.
3. Bake the Base: Bake at 350°F (175°C) for 20 minutes, until the edges are set but the center is slightly soft.
4. Make the Caramel: While the base bakes, heat sugar in a dry saucepan over medium heat, stirring constantly until it melts into a deep amber liquid. Add butter and stir until melted. Slowly pour in cream (it will bubble), stirring constantly. Cook for another 1–2 minutes until smooth. Stir in salt.
5. Add the Caramel Layer: Pour the warm caramel evenly over the baked base. Tilt the pan to spread, or use a spatula.
6. Bake Again: Return to the oven and bake for an additional 15 minutes. Let cool at room temperature for 1 hour before slicing.
7. Finish and Serve: Once cooled, sprinkle with flaky sea salt. Slice into bars and serve.

Tips:

• Let the brown butter cool slightly before mixing to avoid scrambling the eggs.
• Use high-quality espresso powder for best flavor.
• Store bars in an airtight container for up to 5 days or freeze for up to 2 months.
• For easier slicing, chill the bars before cutting.
