1 box Duncan Hines yellow cake mix
1 - 3oz. box lemon Jell-O
1/2 cup canola oil
1 cup Domino's powdered sugar
1/2 cup lemon juice
In a mixer add cake mix, eggs and canola oil--beat. Add Jell-O powder--beat
until smooth. Pour batter into greased 9 x 13 cake pan. Bake at 325 degrees
for 25-28 minutes--test with a toothpick for doneness. Topping: in a mixer
add lemon juice and powdered sugar--beat until smooth. As soon as you
take the pan out of the oven, use a toothpick to poke holes evenly over the
top of the cake (about 1" apart). Spoon the lemon juice topping mixture all
over the top of the cake and smooth it out using the back of a spoon. Cool
completely, and then cut into squares.
