Easy Purple Sweet Potato Cheese Cake with Pancake Mix
I made this easy cake with sliced cheese, milk, yogurt, eggs, purple sweet potato and pancake mix. You can make this with the ingredients you have at home. It's moist, and beautiful with the purple color. We made one for Father's Day! It's also good to serve as a snack.
Peel the purple sweet potato, and cut into 7-8 mm thick wedges. Soak in water for about 10 minutes to remove the bitterness.
Shred the sliced cheese into small pieces.
Put the milk and cheese from Step 2 in a pot, and heat over very low heat. Be sure not to bring it to a boil. Melt the cheese thoroughly, mix well with a wooden spatula, and turn off the heat.
Add the yogurt to Step 3, and mix well until smooth. Add the lemon juice, and mix further (optional).
After 10 minutes or so, drain the sweet potato from Step 1. Cover with cling film, and microwave for 5 minutes (500 W). Mash with a masher while hot.
Combine the egg yolks and 2/3 of the sugar in a bowl, and mix well. (You will use the remaining 1/3 of the sugar to make meringue.)
Add the cheese cream from Step 4 into Step 6, and mix really well.
Add the mashed purple sweet potato from Step 5 to Step 7.
Add the pancake mix to Step 8, and mix lightly. Preheat the oven to 180℃.
Lightly grease a cake pan with vegetable oil, and stick parchment paper inside. Lightly grease the parchment paper with vegetable oil as well. (The vegetable oil is not listed. You can use margarine, etc.)
Whip the egg whites to make meringue. After they're mixed together, add the remaining 1/3 of the sugar in 2-3 batches, and mix to make glossy meringue.
Add the meringue into Step 9 in 3 batches, and fold in gently in a cutting motion.
Pour the batter from Step 12 into the lined cake pan, bake for 30 minutes at 170℃, then bake for 15 minutes at 140℃. Cover with aluminium foil halfway through so that the surface won't be browned too much.
After baking, let it cool a little. Transfer the cake in the cake pan to the fridge to chill. After it's chilled, remove from the cake pan. Cut into your desired sizes, serve on plates, and enjoy.
Story Behind this Recipe
I often make cheese cakes, and I made this since I had the listed ingredients at home. I like trying out my original recipes and make new ones. You can make this cake fluffy like soufflé even without using a double boiler. You can hear tiny bubbles in the cake popping as you cut or bite into it. It's so fluffy and moist. I decided to make this one to be my signature cheese cake.
If you don't have yogurt, substitute the amount of yogurt with milk. You can use Kabocha squash instead of purple sweet potato. Or make this cheese cake with neither of them!! Lemon juice is optional. You can use plain flour instead of pancake mix (make the meringue very stiff if using plain flour). This cake is moderately sweetened, so adjust the amount of sugar to taste.
