Ingredients for alfajor cake

These 13 ingredients create a showstopping alfajor cake that's all about layers and texture.

The butter is everything here—use full-fat and let it sit out for 2 hours before mixing. Land O'Lakes or Plugrá are my go-tos, but any good brand works. For the dulce de leche, La Salamandra or Nocilla are my favorites, but any store-bought jarred version will do. The almond flour? Bob's Red Mill is finely ground and perfect for the crumble topping. Don't skip sifting the flour—it makes the cake layers light as air. And trust me on the vanilla bean paste: it's worth the extra few bucks for that authentic flavor.

No dulce de leche? Homemade caramel sauce with a touch of coconut milk works in a pinch. Short on almond flour? Substitute with extra shredded coconut and a splash of almond extract. The simple syrup can be made ahead—just boil equal parts sugar and water for 5 minutes. For a quicker version, store-bought vanilla syrup cuts the time in half. And if you can't find vanilla bean paste, double the extract—it's not the same, but still delicious. The powdered sugar is just for dusting between layers, so don't stress if you're out—just brush with extra simple syrup instead.

This cake is a make-ahead dream. Assemble it the night before and let it chill—the flavors meld beautifully overnight. Store leftovers in the fridge for up to 5 days, but honestly, it disappears faster than that. For parties, cover with plastic wrap and bring to room temp before serving. The crumble topping stays crisp for 3 days if stored in an airtight container. And if you make a double batch? Freeze one cake for up to 3 months—just thaw overnight before serving.

Step-by-step instructions for alfajor cake

Here's how to create layers of nutty almond goodness with caramelized dulce de leche filling.

In a food processor, combine the 1.5 cups almond flour, 0.5 cup shredded coconut, 0.5 cup powdered sugar, 1 tsp vanilla bean paste, and 0.5 tsp salt. Pulse until the mixture resembles fine crumbs with no large almond pieces remaining. This base will give your cake that signature crunchy texture that sets alfajor cakes apart.

Transfer the almond mixture to a bowl and stir in 1 cup of the 2 cups dulce de leche using a silicone spatula. The dulce de leche should coat the crumbs evenly, creating a moist but still crumbly texture. Press this mixture firmly into a 9-inch springform pan lined with parchment paper, creating an even layer. Here's the thing—press down gently but firmly to ensure it stays compact during baking.

Preheat your oven to 350°F. Bake the almond base layer for 12-15 minutes until the edges are lightly golden and the center feels set when pressed gently. Don't overbake—you want it firm but still tender. Remove from the oven and let it cool completely in the pan before proceeding. This cooling step is crucial to prevent the layers from becoming soggy when you add the filling.

While the base cools, prepare the simple syrup by combining 0.5 cup granulated sugar and 0.5 cup water in a small saucepan. Bring to a boil over medium heat, stirring until the sugar dissolves completely. Let it cool to room temperature—this syrup will keep your cake moist and add that perfect balance of sweetness.

In a large mixing bowl, cream together the 1.5 cups unsalted butter and 2 cups granulated sugar until light and fluffy, about 3-4 minutes using an electric mixer. This step is where the magic happens—the butter should be pale and nearly tripled in volume. Add the 6 whole large eggs, one at a time, mixing well after each addition. Incorporate the 2 tsp vanilla extract and 1 tsp ground cinnamon, mixing until just combined.

Gradually add the 3 cups all-purpose flour and 0.5 tsp salt, mixing on low speed until just combined. Be careful not to overmix—the batter should be smooth but still slightly lumpy. Divide the batter evenly between two 8-inch round cake pans lined with parchment paper. Here's the trick: tap the pans gently on the counter to remove any air bubbles before baking.

Bake the cake layers at 350°F for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The layers should be golden brown on top but still moist inside. As soon as they're done, remove them from the oven and let them cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and ensures even layers when assembling.

While the layers cool, prepare the remaining filling by warming the 1 cup remaining dulce de leche in a small saucepan over low heat until it's smooth and spreadable. If it's too thick, stir in 1-2 teaspoons of milk to achieve a pourable consistency. Let it cool slightly before using—this ensures it doesn't melt the cake layers when assembled.

Place the first cake layer on a serving plate and brush it generously with the simple syrup you prepared earlier. This step adds moisture and helps the layers stick together beautifully. Spread a layer of the warmed dulce de leche evenly over the cake, leaving a ½-inch border around the edges. Here's where it gets fun—sprinkle half of the remaining 0.5 cup shredded coconut over the dulce de leche.

Place the second cake layer on top and brush it with more simple syrup. Spread the remaining dulce de leche over this layer and sprinkle the rest of the shredded coconut evenly on top. Press down lightly to ensure everything adheres. Wrap the assembled cake tightly in plastic wrap and refrigerate for at least 4 hours, or preferably overnight. This chilling time allows the flavors to meld and the cake to set properly, resulting in clean slices every time.
