Preparation
Batter
Whisk together walnuts, flour, baking powder/soda, salt, cinnamon and nutmeg. Set aside. In the bowl of a standing mixer, beat at medium speed eggs, oils, and brown sugar for about 3 minutes. Add vanilla and pumpkin and beat until just smooth. By hand, stir in flour mixture just until completely moistened. Scrape into prepared pan and bake for about 34-35 minutes until browned and tester comes out clean. Remove from oven and rest in pan on rack for 10 minutes, then remove from pan to cool completely.
Buttercream
Creme Anglaise
Have at the ready a fine mesh sieve over a metal bowl. Whisk the egg yolks until smooth and have near the stove. In a small saucepan, scald milk and lower heat just to keep it warm. In another small saucepan, combine sugar and water. Stir until all of the sugar is moistened and then apply medium heat, stirring constantly until the sugar syrup comes to a boil, then stop stirring and let boil until an instant-read temperature reads 370* and the syrup is a deep amber. Immediately remove from heat and add the hot milk. Stir over very low heat until the caramel is completely melted and smooth. Temper the egg yolks with the caramel, whisking the caramel little by little into the egg yolks, then return the mixture to the pan and apply medium heat, stirring constantly until the mixture reaches 170* then immediately remove from the heat, pour through the sieve and press to strain all of liquids from the solids. Cool to room temp.
Italian Meringue
Have at the ready a glass heat-proof measure. In a small saucepan combine sugar and water. Stir until all of the sugar is moistened and then apply medium heat, stirring constantly until the sugar syrup comes to a boil, then lower heat to just a simmer.
In a medium bowl with a hand mixer, blend egg white until just foamy. Add cream of tartar and beat at medium high until soft peaks form. Slowly start to add 2 tsp. of sugar and beat at high to stiff peaks form.
Return to the syrup, raise the heat back to medium and boil until the instant read thermometer reads 250*. Immediately pour the syrup in the glass measure to stop the cooking. With the beaters on high slowly pour the syrup into the meringue, avoiding the beaters and then lower the speed to medium high and beat for 2 minutes. Refrigerate the meringue until the instant read thermometer reads 70* then proceed.
Buttercream
In the bowl of a standing mixer with whisk attachment, beat butter on medium for 30 seconds, slowly beat in the creme Anglaise until smooth. Add the Italian meringue and beat until just incorporated. Beat in orange juice concentrate and zest. Remove about 2 tbs. of the frosting to a small bowl to tint with food coloring an intense shade of orange then stir that in to tint the rest of the frosting.
Frost the cake, and decorate with marzipan leaves and tendrils.
Note: If you want to make this cake, let me know and I’ll loan you the special pan and give you some walnut oil as you only need a little and can only buy it in a big can.
Whew – I can’t believe how much work this was, another one you’ll probably not see again.
