It’s perfect for festive occasions like New Year’s Eve, a milestone birthday or another very special event.

Most often we make our seafood smörgåstårta that is similar, and quite impressive as well. But when we want to pull out all of the stops, it’s this lobster sandwich cake.

In other words, if you want to go big, then this lyxig skaldjurs smörgåstårta (luxe shellfish sandwich cake) literally takes the cake!

Since lobster and other types of shellfish are expensive, we reserve this for very special times of the year. Although it is pricey, we find that ordering nice takeout for 8-10 people is also quite expensive. So, for perhaps a little more cost, in the end, it is good value when you make your own food at home.

Plus, you don’t have to include all of the seafood we’ve shown. You can decorate the top with fewer seafood ingredients and it will still be a great sandwich cake.

And, if you like, you can substitute one or two of the seafood sandwich fillings with less expensive fillings, such as tuna salad and salmon salad.

How To Make Lobster Sandwich Cake

It’s not as difficult to make a sandwich cake as it would seem. To start, you will need to combine the ingredients for four separate sandwich mixes.

You will also need to combine the ingredients for the savory frosting that helps the cake hold together as well as meld the flavors.

We like to make these ahead the night before we make the sandwich cake. That way, it is much easier to prepare the cake the next day.

You don’t have to though, if you don’t mind doing it all in one day, that’s totally up to you. So, once you decide on your four sandwich fillings and make them up, then you can move on to the cake assembly process.

We use a low carb, gluten free bread called Carbonaut. You can substitute other bread types, of course, but if you are minding carbs, this bread works well.

Cut the crusts off the bread slices and arrange the first layer of bread on the serving platter. Spread on one sandwich filling. Add another layer of bread slices. Continue with the next sandwich filling. Repeat with the next bread layer, and so on. Until you have reached the top of the cake.

Then, you will need to garnish the sides and top of the sandwich cake, using your creativity. You can follow our stepwise instructions to garnish as we have done if you like!

What To Serve With Lobster Sandwich Cake

You won’t need very much to go with this as it is quite rich and filling as is. Although, if you’d like to, you can make Red Lobster style shellfish pita pizzas or another seafood pita pizza, like clam white sauce pita pizza or crab melt pita pizza.

We served those alongside this sandwich cake and it was a really good combination.

Serve with sparkling pear or apple cider.

Preparation and Storage Tips

We recommend preparing at least some of the sandwich fillings the night before you make this. Refrigerate the fillings in separate bowls, covered, until you need them.

That way, the cake will be easy to assemble and garnish the next day and will not overwhelm. If you have enough time, and don’t mind it, you can certainly make the whole cake, fillings and all, on the same day.

You will need to hard cook your eggs in advance.

We use our Instant Pot to cook eggs.

Just place a trivet in your Instant Pot with 1.5 cups water. Place your eggs on the trivet, fasten lid and set to 5 minutes on HIGH pressure, with 2 minutes of natural release. Once that is complete, place the cooked eggs in an ice bath, fully submerged in the cold water for 5 minutes.

To learn more about how to cook eggs in an Instant Pot, see our Instant Pot hard boiled eggs recipe.

If your seafood needs to be cooked, you will need to do that in advance of the sandwich fillings as well.

We had cooked lobsters and crab legs that we removed the meat from. You will need shellfish tools to help crack the shells.

We also had some uncooked jumbo shrimp and lobster tails that we baked in the oven for about fifteen minutes at 450°F (230°C).

When you have your cooked eggs and seafood meat removed, you can make the sandwich fillings. Four fillings are needed for this (egg salad, shrimp salad, lobster salad and crab salad). You can substitute tuna salad, salmon salad or smoked salmon salad for one or more, if you like.

You need the savory sandwich frosting, to use around the edges of the cake. Mix up a batch of labneh, sour cream and the rest of the ingredients.

Cut the crusts off of your bread, making similarly sized rectangles to keep the cake layers uniform in size.

Place the base bread layer on a serving platter just sightly larger than the base bread layer. Continue to assemble the cake right onto the serving platter.

Spread each filling onto a bread layer and add more bread layers and fillings until the sandwich is finished.

Garnish the sides and top of the sandwich cake with additional seafood, grapes and vegetables.

Once your smörgåstårta is assembled, you can keep leftovers in the fridge for 2-3 days, although we would recommend enjoying it within a day or two for the freshest flavor.

More Sandwich Cakes
