Lemon-Frosted Pistachio Cake

Step 1

Preheat oven to 350 degrees. Line the bottom of an 8-inch nonstick cake pan with parchment paper.

Step 2

In a mixer fitted with a paddle, cream together the butter and superfine sugar until light and fluffy. Add the eggs one at a time, then add the ground pistachios and almonds. Add the orange juice, orange zest and rosewater, and mix well. Using a rubber spatula, fold in the flour; do not overmix.

Step 3

Scoop the mixture into the cake pan, and bake until the top is firm and a light golden brown, about 40 minutes. Lightly cover the top of the cake with foil and continue baking until a toothpick inserted into the center comes out dry, about 10 minutes. Allow the cake to cool in the pan for several minutes, then remove and cool on a rack.

Step 4

When the cake is cool, make the icing: mix the confectioners' sugar and lemon juice together in a small bowl, and pour over the cake. If desired, decorate with crystallized rose petals and pistachios. Allow the icing to set for 30 minutes before serving.
