Mini Green Tea Cake

Mini Green Tea Cake 2It’s been forever since I posted something on the blog.  This is what happened…  The weekend before I left for my vacation to Korea, I made a wedding cake, mini wedding desserts and did desserts for a confirmation banquet.  It was jam packed with sugar, whipped cream, flour and butter.   At this point, I was so sick and tired of seeing ingredients I had to take a break.  If you follow me on Instagram, you probably saw that I went on a two week vacation to South Korea and by the time I got back, I was so jet lagged I didn’t have it in me to do anything.  And so here I am, three weeks later posting a new recipe for you guys.  I think I’m sufficiently rested and I hope to continue on this culinary journey with you with no more stops in the road.
Mini Green Tea Cakes 4This green tea cake was inspired by my trip to O’Sulloc Tea Museum in Jeju, South Korea.   Unfortunately the weather was horrible the day we went and I wasn’t able to see the plantation but, I did enjoy some green tea desserts.Mini Green Tea Cakes 1I paired my cake with both red bean and sweet potato frosting.  The slight bitterness of the green tea balances well with the smooth creamy sweet potato and the red beans give it a pop of interesting texture.  While we are talking about sweet potatoes, I should let you know that I do not mean the orange fleshed American sweet potato.  This is the potato I am talking about.   The Korean/Japanese sweet potato has purple skin and yellow flesh.  When baked, it tastes slightly like a perfectly roasted chestnut and is less water logged than its American cousin. With that bit of information, I hope you give it a try! Enjoy 🙂Mini Green Tea Cake 3
