I’m sharing a very special recipe with you today for a very special day…it is TheBetterHalf’s 30th Birthday! He’s finally as old as I am, at least for the next 6 months. He was complaining the other day about getting old. I told him he would get no sympathy from me! Welcome to 30 – it isn’t so bad!

I love celebrating birthdays on the blog – it is nice to have an excuse to make a decadent birthday treat (not that I need an excuse to bake…). Growing up, Texas Chocolate Sheet Cake was one of TheBetterHalf’s favorite desserts, so I got the recipe from his mom to make for his birthday. I was nervous to bake a family favorite, because I didn’t want to mess it up! Luckily, he said this chocolate sheet cake was just as good as he remembered it.

I can see why this was a family favorite recipe….this cake is GOOOOOOD. Dangerous in fact. I had to cut the cake into slices and freeze it pretty much right after the photoshoot because we couldn’t stop eating it! The cake is so light and fluffy. There is a hint of cinnamon in the batter, which gives a subtle flavor that tastes awesome with the cocoa! The icing reminds me of the taste of fudge, and the texture is incredible.

The one tricky part about making this cake is the icing. You want it to be super smooth so that the top of the cake can get that smooth, perfect texture but the powdered sugar can get lumpy. If you sift it first, and then whisk the warm frosting like crazy, you should be lump-free!

So, how cute is that spoon? I bought it for TheBetterHalf – I think I might like it more than him though! It is from For Such a Time Designs in case you need to get one for yourself!  I also got a custom Chez CateyLou spoon.  So cute!

Happy Birthday to my favorite person in the world! I hope you actually read this post!

We are going to Momofuku Ko tonight to celebrate!  We love David Chang (Ssam Bar is one of our favorite restaurants in the city) and can’t wait to try out this acclaimed restaurant for the first time!

    Happy birthday to your hubby! Your night out sounds fantastic!! So jealous. And extra jealous of this cake!! My mom made Texas Sheet Cake for us a lot growing up, but I haven’t had it in forever. You’ve inspired me to give it a go — gluten-free of course :)

    The first time I had Texas sheet cake I was FLOORED. I think it’s the icing on the top that makes it so great for me. The crackles kill me! SO GOOD! It’s like the best brownie got with the best cake and made a dessert baby. Ugh. I die. I hope your hubby had a wonderful birthday!!
