🧾 White Texas sheet cake ingredients

It's so weird how a few simple ingredients can end up being such an amazing cake.

What to do with leftover buttermilk....

📖 Variations

Honestly, I wouldn't change too much about it!

• You can substitute almond flavoring for coconut flavoring if you prefer.
• You can substitute sour cream for the buttermilk - use an equal amount.
• Use another type of nut.
• You can melt the butter and let it turn golden brown before adding the water. It gives it a nutty flavor that is delicious.
• Use an equal amount of sour cream for the buttermilk.
• Try almond extract instead of coconut flavoring.
• Some people leave out the pecans. You *could* do that but it will make any Texans in the room twitch.

I'm telling y'all this version of Texas sheet cake is so good! It's become on of my favorite cakes and even my dyed-in-the-wool chocolate lovers are obsessed with it!

🔪 Instructions

Note: This is an overview of the instructions. The full instructions are in the green recipe card below.

1. Mix the dry ingredients in the large bowl of a mixer. Set aside.
2. In a small bowl whisk the flavorings, eggs, and buttermilk together. Set aside.
3. Melt 1 cup butter in a large saucepan on top of the stove. Add the 1 cup water and bring to a boil.
4. Pour the hot butter mixture over the flour mixture in the bowl beating on low. Add the buttermilk mixture. Beat for one more minute then pour the cake batter into the prepared pan. Bake at 350 degrees F for 20 minutes.

2. Remove from heat and add the Confectioner’s sugar, pecans, coconut flavoring, and vanilla.
3. Mix quickly and spoon over warm cake.
4. Smooth to cover the whole top.

🥫 How to store leftovers

Cover with plastic wrap or aluminum foil and store at room temperature for up to about 5 days (I can't imagine it not being gone within hours but that's my house).

You can store it in the refrigerator if you want but I think it has the tendency to dry it out.

You can also wrap it in plastic wrap, then aluminum foil and freeze for up to 3 months. The day you plan to serve it let it thaw at room temperature.

I like to cut it into squares and freeze it in small Ziploc bags or in an airtight container with parchment between the layers.

It's perfect for tossing into school lunches!

💭 Things to know

Expert tip: The frosting should be almost pourable and goes directly on the warm cake. If you have to spread it too much the top is going to tear. Spoon it on and move it around gently.

• You might want to sift the powdered sugar if it seems to have lumps.
• It's a good idea to use everything at room temperature. If your eggs are cold put them in hot water for a minute or two - not hot enough to start them cooking just hot like hot dishwater.
• Toast the pecans lightly. I like to chop them and then toast them because that way all the sides get toasted. The flavor is out of this world and every time I make something with pecans people wonder what I've done differently than they did. It makes a huge difference.
• Use a heavy cookie sheet with sides or a 15x10-inch jelly roll pan. This should not be much more than an inch thick. If you end up with a cake 3 inches thick it wasn't made by a Texan!
• I use salted butter in this. I like the flavor it gives.
• If you can stand to do it, cover the finished cake and let it hang out on the counter overnight. The flavors really develop.
• I've seen people sprinkle the nuts on top of the frosting. Ummm - no. Stir them in so they are part of the frosting not an addition to it.
• Like the classic southern dessert, Coca Cola cake, Texas sheet cake is never served with buttercream frosting. Just no.

Notes

Storage:

Cover with plastic wrap or aluminum foil and store at room temperature for up to about 5 days or freeze for up to 3 months.

You can store it in the refrigerator if you want but I think it has the tendency to dry it out.

Tips:

• The pan size is not exact because cookie sheets are different sizes. The cake, when baked, should be about 1 to 1-½ inches thick. The pan sizes in the instructions should work fine.
• Use everything at room temperature. If your eggs are cold put them in hot water for a minute or two - not hot enough to start them cooking just hot like hot dishwater.

• Toast the pecans lightly. I like chop them and then toast them because that way all the sides get toasted. The flavor is out of this world  and every time I make something with pecans people wonder what I've done differently than they did. It makes a huge difference.
• Use a heavy cookie sheet with sides. It should not be much more than an inch thick. If you've got a 3 inch thick Texas sheet cake it wasn't made by a Texan.
• I use salted butter in this. I like the flavor it gives.
• If you can stand to do it, cover the finished cake and let it hang out on the counter overnight. The flavors really develop.
• I've seen people sprinkle the nuts on top of the frosting. Ummm - no. Stir them in so they are part of the frosting not an addition to it.
• Texas sheet cake is never served with buttercream frosting. Just no.
• The frosting should be almost pourable and goes directly on the warm cake. If you have to spread it too much the top of the cake is going to tear. Spoon it on and move it around gently.
• Substitute almond extract for the coconut and almonds for the pecans... if you must.
