Strawberry jam filled cupcakes are so easy to make from scratch!! Curd or yogurt makes the cake soft and moist. Do you know what is best thing about strawberry jam ?? well, the answer is simple...you can have strawberries when they are not in season....and make cupcakes or cakes ....when you have that strawberry craving ....like I had! I know summer is not the best time to bake, at least when ice creams and frappuccinos are ruling.....but, I-had-to-eat-a-strawberry-cup-cake-feeling; which was overpowering!! So I ransacked my refrigerator and found two jars of organic strawberry jam which I bought from Nelliyampathy Hills and I had completely forgotten about them (HOW-COULD-I??). Like any strawberry-holic, I opened the can and dipped my finger in it and ....yum!! it transported me to strawberry land.....they were so good! If you have fresh strawberries at hand, don't bother the jam, use fresh ones...puree them in a blender or food processor..
