Ingredients
Method
- Preheat your oven to 180c/350f.
Make the Caramel Layer
- In a pot or pan, add sugar.
- Place on medium heat and keep heating and stirring until the sugar melts and turns amber.
- Pour the caramel into an 8-inch cake tin and set it at room temperature.
- Do not grease the tin; an un-greased tin helps the cake rise better.
Make the Flan
- In a large bowl, combine all the ingredients for the flan.
- Whisk the ingredients together.
- Pour the mixture through a sieve into the tin on the caramel layer.
- Ensure the sugar has set before pouring the flan mixture.
- Set it aside while preparing the cake batter.
Make the Cake Batte
- In a large, clean bowl, add egg whites and cream of tartar.
- Begin whipping until the mixture becomes foamy.
- Gradually add sugar, slowly whipping until you achieve stiff peaks.
- Mix egg yolks and sugar in a separate large bowl until the egg yolks lighten in color and the mixture slightly increases in volume.
- Add oil, water, and ube extract and whisk until combined.
- Add flour and baking powder and mix until combined.
- Gently fold in half of the whipped egg whites, followed by the rest, ensuring no lumps or streaks of egg whites remain.
Bake the Cake
- Place the tin in a baking/roasting tray with high sides.
- Pour boiling water into the large tray until it reaches halfway up the sides of the tin.
- Carefully place this in the oven and bake at 180c/350f for about 55-60 minutes, until a toothpick inserted into the cake comes clean. The cake will be jiggly due to the flan; this will set as it cools.
- Remove from the oven, let it cool completely, then refrigerate overnight.
- Take it out of the tin the next day, cut it into slices, and enjoy!
