3. Directions:

3.1 Preheat

Preheat the oven to 350°F.

3.2 Prep

Grease a 9×13-inch pan with nonstick cooking spray or butter. Line with parchment paper or dust with flour, shaking out excess. Set pan aside.

Place the oil, brown sugar, granulated sugar, and vanilla in stand mixer bowl or large mixing bowl and whisk to combine.

Add eggs and yolks, one at a time, whisking after each addition. Add the pumpkin puree and whisk until blended.

Put a sheet of parchment paper or a large plate on a work surface and sift the flours, baking powder, baking soda, salt, and spices onto it. Use paper to pour dry ingredients into wet in 3 additions, folding them into batter until blended. Do not overmix.

Thoroughly scrape batter into the prepared pan and smooth the top with a spatula.

3.3 Oven

Bake the cake on middle rack of oven for 20 minutes.

Rotate pan and continue baking until a toothpick inserted in center of cake comes out with a moist crumb or two, 15-20 minutes.

3.4 Check

Check to see that cake is done. Remove from oven or add time as needed.

3.5 Prep

Set pan on a cooling rack. When cake is cool enough to handle, about 30 minutes, invert onto a serving platter to cool completely. Meanwhile, make the frosting.

Place the butter in stand mixer bowl. Mix on medium speed until smooth, scraping bowl as needed.

Put a sheet of parchment or a large plate on a work surface and sift the sugar, salt, and cocoa powder onto it. Use paper to pour dry ingredients into butter a little at a time, mixing on low speed to incorporate between each addition.

Add the bourbon and then cream, beating on medium speed and scraping bowl as needed. Add the vanilla and beat on medium speed until frosting is light and fluffy, 3-5 minutes. Cover bowl and set frosting aside until cake is cool.

Tuck strips of parchment paper or waxed paper under cake to keep platter clean while you frost. Generously spread cake with frosting, leaving sides bare if you like. Carefully pull out strips of parchment.

3.6 Serve

Cut cake into slices and serve. Store leftovers at room temperature loosely wrapped in plastic wrap or draped in parchment paper for up to 3 days.
