Deliciously moist, fudgy & chocolaty Texas style sheet cake
This Texas Sheet Cake recipe has been on the horizon for a while, and when I say “a while”, that means since we lived in Texas 10 years ago.  Not sure why it took so long to recreate it, but this recipe was worth the wait but right on time for any upcoming birthday parties, baby showers, Summer get-togethers or weekend bbq’s.

Allergy friendly, GF Texas Sheet Cake

To me, this Texas Sheet Cake is truly one of the BEST top 8 Free cakes I’ve had or made! It is moist and melty, rich & chocolatey and will most definitely cause some loud moans from those who take a bite.  And there is NOTHING wrong with that because who doesn’t love a little chocolate on chocolate?

My version of Texas sheet cake is free from gluten, nuts and it’s vegan because EVERYONE should be able to eat cake!  To get serious for a moment, this recipe is a love story to my Texas born son who was diagnosed with multiple food allergies before his 1st birthday.  I once thought he’d miss out on cakes & cookies but that’s when I started creating recipes that were safe for him.  Because of him, I see dessert differently and instead of thinking about what he CAN’T have, I see what he CAN have.  I want that for you to!

The ingredients are easy to find and substitute BUT the one thing you can’t leave out is the star of the show….. fruity soda!  Yep my friends, soda. Can I get a “yee-haw“?

Fruity soda makes this Texas sheet cake & frosting amazing & cause your taste buds to do a little dance in your mouth. Keep it healthier & choose Dr. Zevia which is GF, Vegan & free from all the yucky sugars.  If you’re like “It’s cake and I’m using the real stuff“, then go for it and pop open a can of Dr. Pepper or Cherry Coke.

Then get your forks ready!  Once this cake comes out of the oven, you’ll be pouring the warm fudgy frosting all over this decadent Texas sheet cake and be digging in!  IF you let it sit a minute, the frosting will start to crackle and that short wait is worth it, but not all of us have been given the virtue of patience!

      Right? The pop makes it extra soft & adds that little spice. And I LOVE that you call it pop btw! Since I moved to the states, it’s hard to find others that call it that.

    […] Until then, I’m relying on markets for my veggies and one of my favorites to buy would be zucchini. They are everywhere right now and I usually buy a ton. Some of them are eaten sliced and raw. Others are baked or added to a quick stir-fry but my favorite use of zucchini is by adding their grated shreds into breads.  I was saving a few as per my daughter’s request to make the Chocolate Chip Zucchini Bread from my early blog post but I decided to change it up a bit.   How about chocolate cake?
