I made a Sour Cream and Lemon Pound Cake for her birthday cake since she loves lemon desserts. I had a hard time figuring out what to make her, as she kept insisting I bake something the rest of us wanted (like um, chocolate!). Well that wasn't going to happen, it was HER day! The cake came out delicious, but doesn't look very pretty. I would make this again... I followed some recommendations in the comments for this recipe and tripled the lemon zest, added a little more lemon juice, and topped it with a glaze (powdered sugar, lemon juice, and zest). Here's a picture of how it turned out... As usual I had trouble getting it out of the pan, so I just flipped it upside down which actually did better I think for the lemon glaze.
Happy Birthday Granny! I love you more than I could ever put into words.
