Commonly Asked Questions

How do I store the pistachio cake?

To keep the cake fresh, store it in an airtight container in the refrigerator for up to 4-5 days. The frosting contains cream, so it’s best not to leave it out for more than a couple of hours.

Can I make the cake ahead of time?

Yes! You can bake the cake layers a day or two in advance and store them, unfrosted, in the fridge. The frosting can also be made ahead and refrigerated until you’re ready to assemble the cake.

What makes Wonderful Pistachios No Shells Unsalted perfect for this recipe?

These pistachios are already shelled, which saves a ton of prep time. Plus, the unsalted variety lets the natural, nutty flavor shine through without added sodium.

Can I use a different type of nut for the frosting?

While pistachios are the star of the show, you could use almonds or walnuts if needed. However, the flavor and texture will change, so pistachios are definitely recommended.

Why is there lemon in the cake?

The lemon zest and juice add a bright, citrusy flavor that complements the pistachios beautifully. It also helps balance the sweetness of the cake and frosting.

How do I get the frosting extra smooth?

Make sure your butter is at room temperature and beat it thoroughly before adding the sugar and pistachios. If the frosting is too thick, add a splash of cream to loosen it.

Can I freeze the cake?

Absolutely! Freeze the unfrosted cake layers for up to three months. Wrap them tightly in plastic wrap and foil. When you’re ready to serve, thaw the layers in the fridge overnight, frost, and enjoy.

What’s the best way to grind the pistachios?

Use a food processor and pulse until you reach a fine texture. Don’t over-process, or you’ll end up with pistachio butter. For this recipe, you want a slightly coarse, flour-like texture.
