Hello! I hope you are all having a wonderful week so far. I am super pumped to bring y’all this classic cake recipe today. It is moist and chocolatey, but also extremely easy. It does not require any layering or fancy decorating. Just bake the cake on a sheet pan and then pour the icing on top. Have you ever had a sheet cake before? If not, prepare yourself for something unbelievably delicious. I know I know, it seems like I’m being biased about how great this cake is because it has Texas in the title and I also live in Texas. I assure you that is not the case. Would I lie about whether or not a cake is amazing? NEVER.

Life has been insanely busy lately with a variety of wedding events along with further adjusting to my unit at work. Both of those things are extremely exciting, but it’s always important to take a step back and return to your normal routine every now and then. My normal routine? Making yummy treats, of course! What do you like to do to relax and take a break from the craziness of life? Maybe some of you have some unique relaxation methods I should give a try! For now though, it’s time for cake.

Firstly, preheat your oven to 350º. Grab the first three ingredients and let’s get cracking! In a medium saucepan, bring the spicy cola drink (Dr. Pepper in my case), oil, and unsweetened cocoa powder to a boil. Make sure to whisk it frequently throughout. If you leave it cooking for a couple of minutes without stirring it could boil over and burn. Once it gets to a boil, I let it cook for a minute or so before removing it from the heat.

While your cola mixture is cooling down for a bit, grab your dry ingredients. In a large mixing bowl whisk together your flour, granulated sugar, brown sugar, baking soda, and salt. Pour in your slightly cooled chocolate mixture and gently whisk just until combined. Gently whisk in the buttermilk, eggs, vanilla, and cinnamon. You’ll be left with a silky smooth caramel texture. Dang, now I want something with caramel in it…I’ll keep that one in mind for the future 😉


Lightly grease your sheet pan (17 1/2- x 12 1/2- inch sheet pan) then pour in that silky smooth batter. Place in oven and cook for around 18 minutes. Go ahead and check it earlier if it looks nice and springy. If a toothpick comes out clean, it’s ready to be taken out. I know it’s going to be tempting, but don’t eat the cake yet! Let it cool completely and then you can start preparing that super yummy icing.

For the icing, grab a medium saucepan and cook the butter and chocolate over medium-low heat until they are melted. Make sure to stir consistently to avoid the chocolate burning. As soon as they are melted, remove from heat and turn off your stove. Whisk in the spicy cola drink and milk. Then gently whisk in the powdered sugar, vanilla, and pecans. Now all you have to do is pour the icing over the cake. It really doesn’t even need to be spread.


Even after the icing has set, it is still nice and soft. If you want it a bit thicker and sweeter, add 1/2 cup or more of the powdered sugar during the preparation. Don’t get me wrong, I love all things sweet, but I think the icing already balances rather well with the cake.

I must admit that I didn’t make it very long before cutting out a huge piece of this along with some vanilla ice cream. No shame! This cake does stay insanely moist for days though. Not like the cake will even last that long…


I’ll be the first to acknowledge how old this plate is that I photographed on. It’s a classic though, just like this recipe, so it balances out! Maybe I enjoy this recipe so much because I love classic things. I enjoy watching westerns with my grandpa, old school musicals and Doris Day movies, and many many other things. What do you enjoy that you consider to be classic?
