Limoncello Pound Cake with Mascarpone-Lemon Frosting

Can we ever really get enough lemon cake in life?  And can lemon cake ever really be lemon-y enough?  These are the kinds of questions that I ponder unceasingly; the kind of questions that keep me awake at night and distracted during the day.  I know, I know.

So it was that on the occasion of my daughters’ birthdays a couple of weeks ago I sought the answers to those questions.  We are true lemonheads, us three, so there wasn’t even a question of what kind of cake I would make; just how lemon-y I could actually make it.

The answer, in the end, was very lemon-y indeed. 

On the outside chance that you, too, lie awake at night scheming how to get more lemon into your life, here’s a very simple primer…

1.  Make this pound cake, substitute limoncello for the vanilla and add 2 teaspoons of lemon zest to the batter.

2.  As the cake cools, puncture holes into the top with a wood or metal skewer (make sure the holes get down through the middle of the cake).

3.  Drown Drizzle the cake with limoncello and let it soak in.

4.  Mix together lemon curd and mascarpone cheese.

5.  Cut the cooled cake in half and spread the lemon curd frosting over the bottom half.

6.  Replace the top half of the cake and spread with the remaining frosting.

7.  Sprinkle the top with freshly grated lemon zest.

Yes, people, yes.  The answer is yes, you can actually get enough lemon into a lemon cake.

For the frosting:

1/2 cup mascarpone cheese, room temperature

1 1/4 cups lemon curd (store-bought or homemade -see recipe below)

2 teaspoons of grated lemon zest

While still warm, puncture holes in the top of the cake and drizzle with the limoncello.  Let this soak in completely.

Mix together the mascarpone cheese and lemon curd, adjusting the amounts of each to your own tastes for how lemon-y or creamy you would like the frosting.

Slice the cake in half horizontally and spread the bottom half with a little less than half of the frosting.  Replace the top half of the cake and spread with the remaining frosting and then sprinkle with the lemon zest.

Lemon Curd

YIELD 1 1/2 cups

Recipe adapted from Martha Stewart

3 eggs

2 egg yolks

1 cup sugar

1⁄2 cup fresh lemon juice (I sometimes add another ¼ cup for extra lemony-ness)

1⁄2 cup unsalted butter 

1 tablespoon lemon rind, grated 


In a heavy, medium saucepan whisk the eggs and egg yolks until well blended and then add the sugar and lemon juice and stir to combine.  Cook over medium low heat, stirring constantly, for about 8-10 minutes or until the mixture is fairly thick and coats the back of a wooden spoon. 

Remove from heat and immediately pour through a sieve or strainer to catch any egg bits.  This also creates a smooth, curd texture. 

Stir in the cold butter pieces and once the butter has melted, add the grated zest and stir to combine.  

Transfer to a tightly covered storage container.  At this point you can refrigerate the curd (it will last for 2-3 weeks) or you can freeze it for much longer.
