I love that chew on top from toasted coconut in the frosting. Last Easter, serving this cake brought back warm memories of my grandma decorating cakes in her small kitchen with the same staple ingredients.
How to Keep Leftovers Fresh
When your cake is fully cooled, pop the pieces in a sealed container and keep them at room temp for up to three days. For longer storage, wrap each one tight and freeze—they’ll last two months. Let 'em thaw fully at room temp for best texture.
Swaps and Alternatives
No sour cream? Use plain Greek yogurt—it keeps things just as soft. Want even more coconut taste? Use a splash of coconut extract, or both coconut and vanilla. If you swap for unsweetened coconut, remember the frosting won’t be as sweet, so check before covering the whole thing.
Serving Ideas
This cake’s awesome with toasted coconut sprinkled over the top. Try with a mug of strong coffee or cold milk for a chill afternoon snack. If you want to make it extra special, fresh berries or a scoop of vanilla ice cream pair perfectly.

A Bit of Cake History
Texas sheet cake comes from Southern kitchens and folks love how easy it is to mix and how moist every slice turns out. Coconut’s a fun twist that’s big at family tables in spring and at holiday get-togethers.
Common Questions
- → How do I stop the cake from drying out?
Butter and sour cream make the cake soft and moist. Don’t bake it too long and use a toothpick to check it’s done.
- → Is unsweetened coconut fine?
Go ahead and use unsweetened coconut if you want. The cake might be a little less sweet, so add more sugar if you like.
- → Should I ice the cake while it’s still hot?
Yep, icing the cake while it’s warm lets the frosting sink in so you get a super yummy, rich layer on top.
- → What’s the best way to save leftovers?
Just cover the cake and leave it on the counter for three days. For even longer, stash it in the fridge.
- → Is this cake okay to freeze?
Definitely! Cut it in squares, put parchment between pieces, and store in a sealed container in your freezer.
