Go! Go to your kitchen right now and make this low carb Peanut Butter Sheet Cake. With a creamy layer of sugar-free peanut butter frosting, it’s a peanut lover’s dream keto dessert.
I have to confess, I was a Texas Sheet Cake virgin until I met my husband. I guess you can chalk that up to the great cultural divide known as the 49th parallel. He once waxed poetic about his mum’s Texas Sheet Cake and I looked at him with that blank expression that says “I do not understand the words that are coming out of your mouth”. I had to get a full explanation of this well-loved American dessert. And then, of course, I had to get a huge serving of it at the next big family gathering. As a lover of anything with chocolate and pecans, it got a huge thumbs up from me. I may or may not have gone back in for seconds. Possibly thirds.
There’s a lot to love about a cake like this. It’s easy to make and assemble, because you just frost it and serve it right out of the pan. What might be viewed as a gauche shortcut for other cakes is perfectly acceptable with it comes to Texas Sheet Cake. It’s also easy to feed a crowd with this low, flat cake, as you can get 20 or more servings depending on the size of your pan. But my favourite part about sheet cake is that it has an excellent frosting to cake ratio. No overly thick layers of sponge cake with a paltry thin layer of frosting here. Every bite has the perfect proportions of cake and frosting.
I know that I am totally messing with tradition by making a peanut butter version of Texas Sheet Cake. What’s really shocking is that I didn’t add any chocolate whatsoever. You know my deep and abiding love of all things chocolate and peanut butter. I was sorely tempted and the thought of drizzling some chocolate over the top did cross my mind a few times. But I wanted pure, unadulterated peanut butter flavour so I gutted it out and fought my chocolate instincts. I simply garnished the top with some chopped salted peanuts instead. And you will be so glad I did! This may have been the best cake I’ve made in a long time.
One little tip: you may want to make this in secrecy when no one is around. Because you won’t want to share the beater-licking duties with anyone else. Mine….all mine!
