A CLASSIC SHEET CAKE RECIPE
Classic cakes just can’t be beat. They are classics for a reason. Cake recipes that are passed down from generation to generation have love written into them. You know that recipe has been tried and tested for decades. This recipe for Texas Sheet Cake is exactly that! This is so moist and full of chocolate and it has the most delicious poured chocolate frosting and chopped walnuts. If you are looking for that perfect cake to serve to your guests, you have to make Grandma’s Texas Sheet Cake recipe! Make Grandma proud!
TIPS AND TRICKS FOR MAKING GRANDMA’S TEXAS SHEET CAKE:
- I use margarine in this recipe because that is what Grandma used. Butter will work but I found after testing that margarine actually produces a moister cake here. I should’ve just trusted Grandma.
- This way this Texas Sheet Cake is made is a more traditional recipe. Some of the ingredients used were popular in baking during the 1950’s when this recipe became really popular. In a lot of early 20th century baking, you’ll see a reference to using “Oleo.” This is an abbreviation of the word “oleomargarine.” Today we just call it margarine. I know people turn their noses up at margarine but I promise you that Grandma does not stear us wrong here! The FDA requires that margarine have at least 80% fat and only FDA approved safe ingredients.
- This is made in a jelly roll pan which is 10″x 15″. It will also work in a larger 12″x17″ but the cooking time needs to be lessened so it won’t over-bake. I guess you could also make it in a 9″x 13″ baking dish but it really wouldn’t be a sheet cake then, would it? I have no clue what the baking time would be on that so you’d have to play it by ear.
- The nuts are optional – obviously. Sometimes I won’t add any nuts to the frosting itself then just add the nuts to the top of one side of the cake so folks have the option of with or without walnuts. Pecans also can be used.
- Make sure to butter and flour your pan so this cake can release nicely.
- A higher sided pan is recommended so the frosting doesn’t go over the sides. I have a 10″x 15″x 2″ pan that works perfect. If your frosting does overflow a bit, just gently push it back over the cake with a spatula.
GRANDMA’S ORIGINAL RECIPE:
This recipe came from my good friend Alli’s Grandma. Every time we make it we feel like Grandma Adele is watching down on us and is just happy that we are using her recipe that has been passed down. This recipe is close to my friends’ heart. Alli is an avid baker and says that this is by far the best Texas Sheet Cake she has ever had in her life. I am honored she is allowing me to share it with you today. Every time we make this recipe, we are thankful for generational cooks like Grandma Adele who keep these recipes alive. As you can see from the card itself, it was a well-used recipe and to have it passed down is truly a gift.

I love this cake and plan to make it today. I was wondering should I SIFT the flour ingredients? I remember when my mom made homemade cakes she always seemed to sift the dry ingredients. Thank you!
Can you substitute rice crispy cereal in place of the pecan nuts?
Ummm I’ve never tried that. I would worry they would soften too quickly and not stay crunchy. If you try it, please let me know!
I used to make these all the time for catering events. For some reason around here the name got lost in the translation. The first time I heard, “OH! You mean Texas Pete Cake!” I laughed. Nope no texas pete in my cake! 😉
Bahaaa – can you imagine Texas Pete Cake? OMG! LOL
Love sheet cakes!! I’ve made chocolate sheet cakes but none that called for sour cream. I will definitely make this recipe. Thank you for all of your wonderful recipes.
BTW, it was North Georgia so you know we used pecans-lots and lots of pecans!
But of course – ha! I love it!
This is the exact same recipe I have used for over 50 years. Besides the great taste, you can have it on the table, start to finish, in about 30 minutes! I remember one family reunion at a cabin at Lake Allatoona (North Georgia) in the 70’s when I made three of these in a row (using the same pan) – as soon as one came out of the oven and was iced, it disappeared and everyone was calling for MORE! Within a two-hour period I baked and watched everyone eat up THREE Texas Sheet Cakes! (It was a big family reunion!)
