⅓ cup pecan pieces
1 ½ cups graham cracker crumbs
¼ cup granulated sugar
½ teaspoon salt
3 tablespoons unsweetened cocoa powder
⅓ cup Butter Olive Oil
2 ounces 70% chocolate, chopped
1 stick unsalted butter, cut into pieces
2 tablespoons all-purpose flour
½ teaspoon kosher salt
¾ cup granulated sugar
2 tablespoons honey
2 tablespoons Espresso Dark Balsamic Vinegar
1 teaspoon vanilla
3 large eggs, room temperature
Whipped Cream Topping
1 ½ cups cold heavy cream
1 tablespoon granulated sugar
½ teaspoon vanilla extract
Preheat oven to 325 degrees.
For bar base/crust, in the bowl of a food processor pulse pecans and graham crackers until finely ground. Add sugar, salt, and cocoa, and mix until well-lended. Dump contents into a mixing bowl. Add Butter Olive Oil and process until moistened.
Reserve 2 tablespoons of the chocolate crumb mixture for topping. Press remainder of wet crumb mixture into an 8-inch square baking dish with fingers. Bake crust for 10 minutes, until set. Transfer to a wire rack to cool.
For filling, melt butter with chocolate in a medium saucepan set over medium heat, stirring constantly. Remove from heat and stir in flour and salt until smooth. Stir in sugar, honey or sorghum, Espresso Dark Balsamic Vinegar, and vanilla. Add the eggs, one at a time, stirring until smooth.
Pour filling into the prepared crust and bake until set and cracked on top, about 30 minutes. Transfer to a rack and cool slightly.
For whipped cream, beat cream, sugar, and vanilla with hand mixer until soft peaks form. Top bars with whipped cream, a drizzle of honey, and reserved crust mixture.
