2 packets unsweetened gelatin
1/2 up oil
1/2 cup cold water
For the glaze:
1 cup powder sugar
1/2 cup freshly squeezed lemon
Just mix the powder sugar and lemon until the sugar is dissolved.
Mix the cake mix and gelatin. Add water and mix until all the dry ingredients incorporated. Add eggs and beat until the mixture is fluffy. Bake for 25 - 30 minutes in 180°C (350°F), depends what kind of oven (I'm just using oven toaster, so it's much longer). Poke some holes in the cake, then spread the lemon glaze. Return the cake in the oven and bake again for 15 - 30 minutes.
Here shows the glazed, a little bit chewy on top, I'll improve this next time :)
I think it would be better in cupcake!
