The BEST Chocolate Sheet Cake

So, today is my birthday. Or.. as my Daddy used to say – ‘Blow the trumpets & sound the horns, for today is the day that Crystal was born!’.

Birthdays aren’t as much fun as they used to be. Back when I was a kid, I looked forward to them. I mean… I got presents. What wasn’t to look forward to?!

But these days… things are different. I mean, I still get a couple gifts here & there. But the thing I seem to get most are more wrinkles. Like really.

sung to the tune of the happy birthday song….

‘Happy Birthday to you, happy birthday to you.

Happy birthday, you have wrinkles. 

And you pee when you sneeze’

Wonderful. 😉

But, if there’s one thing life has taught me… it’s to be thankful. I lost my husband when he was 33… so as much as I hate getting older, I also am thankful to be getting older. Even if I still these wrinkles could suck it.

So, I’m going to hug my kids – and slather on my wrinkle cream – and shove my favorite chocolate cake in my mouth. After all, it is my birthday.

And this my friends… there’s a reason it’s my favorite chocolate cake. It’s a sheet cake for one – but that’s not why it’s my favorite. It’s my favorite because it’s so darn decadent. To the perfectly moist cake to the fudgy icing… it’s perfection really.
