I'm giving myself an "A" for originality; an "A" for flavor; but a "B" for homemade goodness. You see, I went about as easy as you possibly can by using some pre-made items I spotted on the grocery store shelf.
Follow the directions on the package and be sure if you are in high altitude to add the additional flour. Fill the prepared pan ( I used cooking spray) with 3/4 of the batter. Spoon a layer of the lemon filling lengthwise down the center of the pan. I left some room on each side of the pan; really concentrating on making a nice yellow stripe down the middle. I would say I probably used about 1/2 cup of lemon filling. Pour the remaining batter over the top of the filling. I only placed 1/2 the batter in the bottom of the pan on my first attempt and you'll notice that the filling sinks some while baking....that's why I'm recommending 3/4 in the bottom.
Bake in a 350 degree oven for approximately 45 minutes. When cool drizzle a powder sugar glaze over the top of the bread (powder sugar and milk).
I love the extra lemon flavor and the ooey, gooey goodness in the center. I've enjoyed it at breakfast and at dinner with a salad. My husband just had a slice with ice cream on top!
However, you try it ..... just do.....it's yummy!
