For the syrup:

How to Make Tarta San Marcos – Step by Step Guide

1. To start with this Tarta San Marcos recipe, preheat your oven to 350°F (180°C). Line a round cake pan with parchment paper.

2. In a mixing bowl, beat the eggs with the sugar until the mixture becomes pale, thick, and fluffy. This step is key to a light sponge cake.

3. Then sift the flour with the baking powder and salt. Gently fold it into the egg mixture using smooth, careful movements to avoid deflating the batter.

4. Pour the batter into the prepared pan and bake for 25 to 30 minutes, until the cake is golden and a toothpick inserted into the center comes out clean. Let it cool completely.

5. In the meantime, prepare the Spanish cream cake syrup. Heat the water and sugar in a small saucepan until the sugar fully dissolves. Remove from the heat and add the brandy or rum if using. Set aside.

6. Next, whip the heavy cream with the powdered sugar until soft peaks form. Keep refrigerated until ready to assemble.

7. For the yolk topping, combine the sugar and water in a saucepan and heat gently. In a separate bowl, mix the yolks with the cornstarch. Slowly pour the warm syrup into the yolks while stirring constantly.

8. Return the mixture to low heat and cook, stirring continuously, until it thickens into a smooth cream. Remove from heat and let it cool to room temperature.

9. Once everything is ready, slice the sponge cake horizontally into two or three layers. Brush each layer lightly with the syrup.

10. Spread the whipped cream over the bottom layer, then place the next layer on top. Cover the cake with a thin layer of the yolk cream.

11. To finish the Spanish custard cake recipe, sprinkle sugar evenly over the yolk topping and carefully caramelize it using a kitchen torch.

12. Before serving, decorate the Tarta San Marcos with sliced almonds if desired. Chill slightly for cleaner slices, then serve and enjoy.

Substitution of Ingredients

Like other classic desserts, such as Spanish custard tarts, Spanish orange cake, or even fusion-style creations like pumpkin spice flan cake, this cake allows for subtle variations without losing its essence.

The easy San Marcos cake recipe is an adaptable dessert: while the traditional version follows the structure of a Spanish custard layer cake, you can easily tweak several components depending on dietary needs or personal taste.

There are other changes you can make to the ingredients of this authentic tarta San Marcos recipe so more people can enjoy it, such as adjusting the dairy content.

You can replace the whipped cream with a plant-based alternative, like coconut cream as it works well thanks to its richness, though a neutral-flavored vegan whipping cream is also a good option.

If you want a lighter result, you may reduce the sugar in the filling or syrup, since the custard topping already adds sweetness and flavor.

Tips on Serving Tarta San Marcos

Once your tarta san marcos is fully assembled and chilled, it’s ready to be served, though many people prefer to refrigerate it for a little longer to ensure cleaner slices and a firmer texture.

For an elegant finish, make sure the caramelized sugar cake topping is freshly torched just before serving.

This keeps the surface crisp and delivers that signature caramelized sugar cake topping crack when cut.

If you’re serving it after a rich meal, smaller portions work beautifully, as this cake is indulgent thanks to its custard and cream layers.

Pairing it with coffee or espresso is a classic choice.

You can also add subtle variations, similar to other desserts like Spanish caramel cake, chocolate crema Catalana, or Spanish apple cake, by garnishing with almonds or a light dusting of powdered sugar.

How to Store Tarta San Marcos

One of the best things about Spanish San Marcos cake is that it keeps very well, maintaining its flavor and structure for several days. 

This makes it a practical make-ahead dessert, especially for celebrations or gatherings.

Before storing, allow the cake with custard and whipped cream to cool completely if it was freshly assembled.

Once ready, place it in an airtight container or cover it carefully to prevent it from absorbing refrigerator odors.

For better preservation, you can lightly press plastic wrap against the cut surfaces to protect the cream and custard layers. 

This helps prevent drying and keeps the texture smooth.

If you follow those instructions, the cake can last about 3 to 4 days in the refrigerator, preserving its ideal taste and texture. 

Freezing is possible, but the whipped cream and custard may lose their consistency once thawed.

Are you a fan of classic Andalusian desserts? 

Then you should try other favorites such as Spanish chocolate biscuit cake, tarta de chocolate, or tarta de limon, which are equally delightful and perfect for preparing in advance.
