Step 1

Before you make the cornbread, prep the rosemary whipped cream by combining 1/2 cup heavy cream and 2 sprigs fresh rosemary in a small glass jar. Give the jar a good shake or two, before covering and refrigerating until ready to use. This will infuse the whipped cream with rosemary flavor, and will work better in a small container where the rosemary sprigs are completely submerged by the cream.

Step 2

Once you've made the cornbread and you're ready to serve it with the whipped cream, use a fine-mesh strainer to strain out the rosemary sprigs from the cream and into the bowl of a freestanding electric mixer fitted with a paddle attachment. Discard the sprigs.

Step 3

Whip the cream on medium-high speed until soft peaks start to form; add 1 teaspoon granulated sugar and continue whipping until just incorporated. Be careful not to overwhip, or you'll end up with butter!

Step 4

Preheat the oven to 350 (F) and prepare an 8 x 8-inch square baking pan by spraying generously with cooking spray and lining the bottom and sides of the pan with parchment paper, leaving an overhang on two sides of the pan. Spray the parchment paper with cooking spray, and set aside.

Step 5

In a medium bowl, whisk together 1/2 cup plus 2 tablespoons flour, 1/2 cup cornmeal, 1 teaspoon baking powder and 1/2 teaspoon kosher salt. Set aside.

Step 6

In a large bowl, whisk together 2 large eggs, 1/2 cup granulated sugar, 1 teaspoon lemon zest and 1/2 teaspoon pure vanilla extract until fully incorporated. Add 1/4 cup vegetable oil and 2 tablespoons melted unsalted butter, whisking until fully incorporated.

Step 7

Sprinkle the dry ingredients (from the 2nd step) over the surface of the wet ingredients (from the 3rd step), whisking until just combined. It's okay to have one or two flour streaks left at this point, because the next thing you're going to do is add 6 tablespoons buttermilk. Whisk until just incorporated, before drizzling in 2 tablespoons honey. Give a couple more whisks until the honey is evenly spread throughout the mixture, BUT be careful not to fully incorporate. You want streaks of honey visible throughout the batter.

Step 8

Transfer the batter into the prepared baking dish. Toss half of the Concord grapes with the remaining 1 tablespoon of flour until the grapes are well coated. Scatter over cake batter.

Step 9

Transfer to the preheated oven and bake until the cake top sets and is light golden brown around the edges, about 20 minutes. Remove from oven and scatter the remaining half of Concord grapes over the cake top. Continue to bake until the top is golden brown and the top of the cake springs back when gently pressed with your finger, around 25 to 30 minutes longer. Transfer to a wire rack and allow to cool slightly in pan. Serve warm or at room temperature. When ready to serve, use the parchment overhangs to lift the cornbread out of the pan.
