Katie is feeling incredibly grateful.
Yesterday morning, The Chocolate Covered Katie Cookbook reached #1 on Amazon for dessert cookbooks and health & fitness books, and climbed to #4 on the overall cookbook bestseller list. To everyone who ordered the book, thank you so much.
To celebrate, I’m sharing a healthier version of a Southern classic: Texas Sheet Cake. This cake is a staple at barbecues and potlucks—thin, deeply chocolate, and finished with a glossy frosting. It bakes quickly, is easy to slice, and somehow tastes like comfort on a plate. In this healthier makeover, I’ve replaced much of the added fat and sugar with yogurt and reduced sweetener, creating a chocolate sheet cake that stays moist and tender while cutting calories dramatically.
Traditional Texas Sheet Cake can be heavy on butter and sugar. Many classic recipes call for two sticks of butter and several cups of powdered sugar, which adds up quickly. My version swaps in yogurt to provide moisture and structure with far less fat, and trims back the sugar so you still get a rich flavor without the overload. The result is a satisfying dessert that’s friendly to everyday baking and lighter than the original.
This recipe fits a 13 x 9-inch pan and takes under an hour from start to finish. It’s ideal for weeknight baking, potlucks, and anytime you want a chocolate treat that’s a little lighter but still indulgent. The cake is delicious served plain, or topped with the low-sugar frosting included below.
Healthy Texas Sheet Cake
Texas Sheet Cake Healthy Makeover
13×9 pan
Ingredients
- 1 cup spelt, white, or Bob’s gluten-free flour
- 6 tbsp unsweetened cocoa powder
- 1/2 tsp salt
- 1/2 tsp baking soda
- 3/4 cup xylitol or granulated sugar of choice
- 1/4 cup yogurt (I used Wholesoy)
- 1/4 cup oil OR substitute additional yogurt for lower fat
- 3/4 cup water
- 2 tsp pure vanilla extract
- Frosting, as desired (recipe included below)
Instructions
Preheat the oven to 350°F (175°C). Grease a 13 x 9-inch baking pan. In a large bowl, whisk together the flour, cocoa powder, salt, baking soda, and granulated sweetener until well combined. In a separate bowl, mix the yogurt, oil (or extra yogurt), water, and vanilla until smooth.
Pour the wet ingredients into the dry and stir just until combined—avoid overmixing. Pour the batter into the prepared pan and spread it evenly. Bake for 18–19 minutes, or until a toothpick inserted near the center comes out clean. Allow the cake to cool slightly before frosting.
For a simple lower-sugar frosting: combine 1/4 cup plus 1 tbsp powdered sugar with 2 tsp cocoa powder, mixing to remove lumps. Stir in 2 tsp melted buttery spread or milk of choice, then add up to 2 more teaspoons of milk very slowly until you reach a spreadable consistency. Spread over the cooled cake.
This cake is tasty plain or with other healthy frosting options if you prefer. It keeps well stored in an airtight container at room temperature for two to three days, or refrigerated if your kitchen is warm. Serve at room temperature for the best texture.
Nutrition note: This lighter version cuts significant fat and sugar compared to classic Texas Sheet Cake recipes. The original can have several sticks of butter and multiple cups of powdered sugar; this healthier makeover uses yogurt for moisture and much less sugar while still delivering deep chocolate flavor.
