FAQs

Can I use regular limes instead of key limes?

Yes, regular limes work well and still give a bright citrus flavor. Key limes are slightly more aromatic and tart.

What’s the best pan to use?

A bundt pan is traditional, but a large loaf or tube pan also works. Just watch the baking time.

Can I make this ahead of time?

Yes, this cake actually tastes better the next day as the flavors develop. Store tightly wrapped.

Do I need to use buttermilk?

Buttermilk adds moisture and a slight tang. You can substitute with whole milk mixed with 1 tablespoon lemon juice or vinegar.

Can I add lime zest to the glaze?

Absolutely! It adds color and extra lime flavor.

How do I prevent the cake from sticking?

Grease the pan thoroughly and dust with flour or sugar, especially if using a bundt pan with deep ridges.

Is the cake very sweet?

It’s sweet but balanced by the tartness of the key lime juice and zest.

Can I add nuts?

Yes, chopped pecans or walnuts add texture and flavor.

What pairs well with this cake?

Fresh berries, whipped cream, or a scoop of vanilla ice cream are excellent additions.
