Purple Sweet Potato Cream Cheese Marble Cake

Eversince after my first trial on the previous sugee cake, I was so into this butter cake with condensed milk. It was very well received by everyone. My friends were delighted by the aroma.and totally addicted to it from that day onwards. Guess, they're all spoilt by Kristy. Bad Kristy ! haha... So, without hesitate I made another butter cake with condensed milk which includes an extra fancy colour & flavour. The idea was actually inspired by the US Starbuck, info here.

Ingredients :
(A)
250gm  butter, softened
1 cup  sweetened condensed milk
90gm  sugar
4 eggs
1 tspn  'Singing Dog" vanilla bean paste

(B)
250gm  all purpose flour
1 tspn  baking powder
1/2 tspn  salt

(C)
100gm   purple sweet potato, mashed

(D)
150gm  cream cheese
1 TB  yogurt
30gm  sugar

Method :
(1) cream ingredients (D) till smooth & well combined, set aside.
(2) mix together ingredients (B) into a big bowl, set aside.
(3) now, beat together all ingredients (A) till well mixed then fold in mixture (B) till everything well combined.
(4) pour 2/3 of batter to a 8" greased baking pan then beat the remaining batter together with mashed potato till combined.
(5) place the potato mixture to baking tray then slightly stir the mixture to form a swirl.
(6) next, place in cream cheese mixture on top the batter, again make a swirl.
(7) finally, bake at preheated oven 175'C for about 50-60 minutes or till the cake tester came out clean.

I really enjoy anything baked with cream cheese due to the sourish taste of it. I supposed this is another wonderful baked of the day. Hope you all going to have a fabulous week ahead. Enjoy !
