Oreo biscuit is most kids' favourite, my younger daughter likes it as well. Her "beloved" is Oreo Cheesecake but when I told her about baking an Oreo buttermilk cake, she gave me a dubious look as she wasn't convinced the cake would turn out delicious.
I found this recipe from Happy Home Baking's post but it was created by the baker of My Kitchen: My Laboratory . Many of of bakers had tried it and all gave very good comment. This had pushed me to give this recipe a shot.
The original recipe called for plain yogurt but I used buttermilk instead as this was what I had in the fridge. All the bakers feedback that this cake was moist, fluffy and buttery. However, I think it's a lighter cake as it's not as buttery as I expected.
Overall, it still tastes well. My daughter likes it very much. As for me, if I'll to bake again, I think I will increase the butter to 100g as I believe it'll tast better. Pls follow this link for recipe. Cheer!!
