Lemon Pistachio Cake with Mascarpone Frosting

PUBLISHED ON: 03.04.2022

We came across this recipe featured in the Costco Connection magazine and were immediately hooked.  This mega delicious cake is lemony, buttery, nutty and adorned with an icing of mascarpone cheese. It’s elegant, and a little exotic.

The recipe has been made by my husband (he’s the baker in the family) at least half a dozen times securing its place in our family’s “keeper recipe” file.

With mixer on low, alternate adding the dry ingredients (in 3 additions) and the wet ingredients ( in 2 additions), starting and ending with the dry ingredients.

Prepare the frosting: Combine all frosting ingredients in a medium bowl.  Mix just until smooth, being careful not to over mix or curdle the frosting.  Frost the cake, then sprinkle on extra chopped pistachios.  Serve or refrigerate until serving.
