This recipe is originally published in 2019 and is now updated with an improved recipe and pictures.

Hi there bakers! How have you been? I know my posting here on the blog has become so random lately. While I am not really able to bake that much because school is out (hello motherhood!),  and I am very pregnant, I am able to bake some bread for my friend’s blog Kawaling Pinoy. You guys should check those goodies out.

Today, I have something for you that I have made and photographed last year ( along with the Basic Fried Donuts recipe)before I went on a vacation to the Philippines. This Ube Flan Cake is a unique cake that has three layers: a caramel layer, a flan layer and the ube cake layer. 

An Improved Ube Flan Cake Recipe

• It is a simple, icing- free cake that is easy to serve on gatherings, you know, when frosted and fondant cakes are not really the thing of your guests. You can’t go wrong with this simple cake that packs a unique combination of flavor in  every slice.
• This update is to address the issue of flan not setting after baking. I increased the baking time and tweaked the recipe so that it has now a thicker flan for a perfect cake to custard ratio. This is the ube version of the original, Custard Cake.

Ube Flan Cake: Step by Step Process

The caramel layer. Or simply, caramelized sugar. 

• Add the sugar on a 9-inch round baking pan. Set the baking pan over low heat on the stove and allow the sugar to melt.
• Use tongs to swirl the pan around to distribute the sugar as it starts to melt. Be careful as the pan is hot. The melted sugar will slowly turn from clear to golden. Remove the pan from the heat and allow the pan to cool.

The Flan Layer

• Preheat oven to 350 F. Add the egg yolks, evaporated milk, and condensed milk in a mixing bowl. Gently stir the mixture until the yolks are dispersed and the mixture is uniform in color.
• Strain the custard over a strainer. Pour it over the cooled caramel mixture in the pan.

The Chiffon Cake Layer

In a large mixing bowl, beat together yolks and sugar, until the color is lighter and the mixture is frothy. Add the sugar, oil, and the ube flavoring. Stir until blended.

Combine cake flour, salt and baking powder in a bowl. Gradually sift the dry mixture over the yolk mixture. Use a hand whisk to beat the mixture after each addition, until it is lump-free and smooth. Set aside.

In the bowl of a stand mixer  (or use an electric hand mixer), beat the egg whites until frothy. Add the cream of tartar and beat the egg whites until soft peaks form. Gradually add 1/4 cup of sugar and continue to beat until the egg whites form stiff peaks.

Using  rubber spatula, fold a little bit of the beaten egg whites to the yolk batter just to thin it down. Then, in three gradual additions, fold the remaining egg whites to the yolk batter until the mixture is streak-free and uniform in color. Pour and scrape the cake batter over the flan layer in the pan. The pan will be almost full.

• Bake the assembled ube flan at 350 F for 60-75 minutes, or until the cake is set and springy to the touch.
• Allow the cake to cool. To unmold, gently run a knife along the edges of the pan. Turn the cake over gently on a rimmed serving plate and gently tap the bottom of the pan to release the cake.

And behold the yumminess!

Frequently Asked Questions

How do I know if the cake is ready? The cake is ready once the chiffon is set and springs back to the touch. Insert a toothpick in the center of the cake, once it comes out clean, the cake is done.

What If the flan is still jiggly after I turn the cake over? Worry not! There is a solution. As long as it is just a slight jiggle in the middle and not a big wave across the cake, you are still fine. Just allow the residual heat of the cake to cook the flan completely. Let it sit until it is cool, or maybe even chill it in the fridge for an hour. The flan will set as it cools.

Do I need to let the dessert cool down before slicing? Yes, and for the same reason. For custard base desserts like this, you want to cool it completely so the custard will set completely. Slicing it right away may cause the custard to collapse. Or, you can really bake the flan to the point that it so cooked, but you run the risk of over cooking the chiffon.

Ingredients

For the Caramel Layer

• 3 tbsp sugar

For the Custard/ Flan Layer

• 354 ml can evaporated milk
• 300 ml can condensed milk
• 6 egg yolks

For the Ube Chiffon Cake Layer

• 3 egg yolks, from large eggs
• 1/4 cup milk
• 1/4 cup sugar
• 1/4 cup canola oil
• 2 tsp liquid ube flavoring
• 1 cup all-purpose flour
• 1 ½ tsp baking powder
• ½ tsp salt
• 3 egg whites, from large eggs
• 1/4 tsp cream of tartar
• 1/4 cup sugar

Instructions

Make the Caramel Layer

1. Sprinkle the sugar on a 9-inch round baking pan. Set the baking pan over low heat on the stove and allow the sugar to melt. Use tongs to swirl the pan around to distribute the melting sugar. The melted sugar will slowly turn from a clear color to a golden one. Remove the pan from the heat and allow the pan to cool.

Make the Flan Layer

1. Preheat oven to 350 F. In a mixing bowl, add the egg yolks, evaporated milk, and condensed milk. Gently stir the mixture until the yolks are dispersed and the mixture is uniform in color. Strain the custard over a strainer. Pour it over the cooled caramel mixture in the pan.

Make the Ube Chiffon Cake Layer

1. In a large mixing bowl, beat together yolks and sugar, until the color is lighter and the mixture is bubbly. Add the milk, oil, and the ube flavoring. Stir well.
2. Combine flour, salt and baking powder in a bowl. Gradually sift the dry mixture over the yolk batter. Use a hand whisk to beat the mixture after each addition until it is lump-free and smooth. This is a thick batter. Set aside.
3. In the bowl of a stand mixer (or use an electric hand mixer), beat the egg whites until frothy. Add the cream of tartar and beat the egg whites until soft peaks form. Gradually add 1/4 cup of sugar and continue to beat until the egg whites form stiff peaks.
4. Using a rubber spatula, fold about 1/4 cup of the beaten egg whites to the yolk batter to slightly thin it down. Fold the remaining egg whites gradually in three additions, until the mixture is streak-free and uniform in color. Pour and scrape the cake batter over the flan layer in the pan. The pan will be almost full.
5. Bake the assembled ube flan at 350 F for 60-70 minutes, or until the cake is set and springy to the touch, and a toothpick inserted at the center comes out clean.
6. Allow the cake to cool. To unmold, gently run a knife along the edges of the pan. Turn the cake over gently on a rimmed serving plate and gently tap the bottom of the pan to release the cake.
   

Notes

• The cake is done when the chiffon is springy to the touch. Insert a toothpick at the center, and if comes clean, the cakes is ready.
• If in case the flan is still a bit jiggly after turning over, do not worry, the residual heat will cook and set the flan. So, it is important to allow the dessert to cool completely and even chill it in the fridge for about an hour or two. The flan will set completely as it cools.
