Nantais Cake, easy French Rhum and Almond cake

French cuisine is known for its sophisticated pastries, but we also have very simple yet delicious recipes too. The Nantais Cake is a traditional almond and rhum cake that originated in the city of Nantes, in western France. I discovered it when I traveled to Brittany and really fell in love with it.

The Nantais is a simple yet elegant cake, made with almonds, sugar, butter, eggs, and a “touch” of rhum. The result is a soft and fluffy cake with a nutty aroma and a hint of alcohol. The cake is typically baked in a round shape and topped with glazing, giving it a rustic and charming appearance.

One of the best things about this rhum cake is that it is incredibly easy to make, even for those who are not into baking. Simply mix the ingredients together, pour into a cake pan and bake. In just a few simple steps, you can enjoy a taste of traditional French cuisine in the comfort of your own home.

Ingredients to make the best Nantais cake

Rhum: you can use any type of rhum for the cake but if you want a really white icing you will need to use white rhum

Salted butter: it is very typical in Brittany (where Nantes is located) to eat salted butter. This rhum cake is no exception as the recipe calls for it. Use a good quality butter.

Almond flour: we call it almond powder in French. I buy it in bulk at Costco usually. You could also finely grind almond to use for this cake

Tips to get the better Nantais cake

This cake is best served the next day. Prepare it a day prior to serve it so it can develop its flavor.

When preparing the icing, make sure it is nice and creamy. If too runny, add a bit more sugar. On the contrary, if too thick, add a bit more rhum.

Want extra rhum flavor: brush the cake with rhum when you take it out of the oven. It will help reduce the sweetness of the cake and add even more rhum flavors to it. Careful not to give this cake to kids, even if the alcohol in the cake is baked, the icing contains pure alcohol.

I don’t eat/drink alcohol

The Nantais really gets its flavor for the rhum but you can replace it with some lemon, orange juice or even orange blossom water should you want an alcohol free version.

Replace the rhum in the icing by water or lemon.

How to store the Nantais

You can keep it two days at room temperature or up to 7 days in the fridge. Cover it with aluminum or wrap it with plastic for optimal conservation.

You can also freeze your Nantais by wrapping it in plastic for 3 to 4 months.
