Ingredients
Banana Bars
- 1 cup (2 sticks / 227 g) unsalted butter, melted
- 2 cups (400 g) brown sugar
- 1 tablespoon vanilla bean paste
- 2 large eggs, room temperature
- 2 cups (250 g) all-purpose flour
- 1 teaspoon kosher salt
- 2 ripe bananas, mashed, some chunks are okay (about ⅔ cup)
Salted Caramel Buttercream
- ½ cup (1 stick / 113 g) unsalted butter, room temperature
- 2 cups (250 g) confectioners’ sugar, sifted
- ½ teaspoon kosher salt
- ¼ cup (82 g) caramel topping
- 1 ½ teaspoons whole milk, as needed
Instructions
- Prepare the Oven and Pan: Preheat the oven to 350°F (175°C) and line a 9×13-inch baking dish with parchment paper to ensure easy removal of the bars later.
- Mix Butter and Sugar: In a large bowl, use a hand mixer to combine the melted butter and brown sugar until well blended.
- Add Vanilla: On low speed, add the vanilla bean paste to the mixture and mix until fully incorporated, ensuring even flavor distribution.
- Incorporate Eggs: Beat in the eggs on low speed until the mixture is smooth and uniform.
- Add Dry Ingredients: Gradually add the all-purpose flour and kosher salt, mixing well to create the batter without overmixing.
- Fold in Bananas: Gently fold the mashed bananas into the batter, leaving some chunks for texture.
- Bake the Bars: Pour the batter into the prepared pan and bake for 32-36 minutes, or until the center feels set and a toothpick inserted comes out mostly clean with a few moist crumbs.
- Cool the Bars: Allow the banana bars to cool completely in the pan while you prepare the buttercream.
- Make Salted Caramel Buttercream: In the bowl of a stand mixer fitted with the paddle attachment, combine butter, confectioners’ sugar, kosher salt, and caramel topping. Mix on low speed initially until the sugar is incorporated.
- Whip Frosting: Increase the mixer speed to high and beat the mixture until smooth and fluffy, approximately 2 minutes. Add whole milk a teaspoon at a time as needed to reach desired frosting consistency.
- Frost the Bars: Once the banana bars have cooled completely, spread the salted caramel buttercream evenly over the top.
Notes
- Use very ripe bananas for maximum flavor and moisture.
- Be careful not to overbake the bars to maintain their gooey texture.
- Make sure the bars are completely cool before frosting to prevent melting the buttercream.
- The vanilla bean paste can be substituted with vanilla extract if unavailable.
- The salted caramel buttercream can be stored separately and added just before serving for best texture.
