Tips for making the best sugar free chocolate sheet cake
Whisking the ingredients while heating is important. This helps keep the mixture smooth, prevents lumps and scorching, and mixes the ingredients.
More helpful tips for you.
- When heating the chocolate mixture for the cake, take care to not overheat the chocolate mixture. It is best to just bring it just to a gentle simmer, not a full boil, for the best texture.
- The sugar alternatives that work best in this recipe are alternatives that measure just like sugar and that can also be bakes with. A monk fruit-allulose blend or powdered monk fruit blend can give the best texture while avoiding the graininess that can happen with straight erythritol
- It is important that your frost this cake while it is still warm. Pouring the frosting over a warm cake helps it spread evenly and creates that classic glossy Texas sheet cake finish. Then allow the cake to cool completely before slicing it so that the frosting can set as it cool .
FAQ
- What is the best sugar alternative to use?
For the best texture, I like allulose or a monk fruit-allulose blend in the cake batter and a powdered monk fruit sweetener in the frosting. These options tend to taste the most like traditional sugar and help prevent a grainy frosting. - What does sour cream do in Texas sheet cake?
Sour cream adds moisture, richness, and a slight tang that balances the chocolate flavor. It also helps create a soft, tender crumb, which is especially helpful in a sugar free cake where the texture can sometimes be a little drier. - Why do you have to pour the frosting over a warm Texas sheet cake?
Pouring the frosting over a warm cake helps it spread quickly and evenly, creating the smooth, glossy chocolate layer that Texas sheet cake is known for. It also allows the frosting to slightly soak into the top of the cake for extra richness. - Do I have to use pecans in Texas sheet cake frosting?
No, pecans are what are traditionally used. You can leave them out if you prefer a smooth chocolate frosting or if you need a nut-free version. - Can I make this sugar free Texas sheet cake ahead of time?
Yes! This cake is great for making ahead because it stays moist and flavorful. You can bake it a day in advance, let the frosting set, and keep it covered at room temperature or in the refrigerator until ready to serve.
Variations.
- Use walnuts instead of pecans: For a slightly different flavor and crunch, swap the pecans for chopped walnuts.
- Try coffee for deeper flavor: Replace part of the water with brewed coffee to enhance the chocolate flavor without making the cake taste like coffee.
- Add cinnamon: Stir in ½ teaspoon ground cinnamon to the cake batter for a subtle warm flavor that pairs beautifully with chocolate.

How to store Texas Sheet Cake.
Leftover sheet cake should be stored in an airtight container or covered well. When properly stored, it should keep for up to two days at room temperature, refrigerated for up to five days, or frozen for up to a couple of months. I like to first slice the cake and then freeze the pieces on the pan for 30-40 minutes. Once firm, transfer the pieces to an airtight container. If you are stacking them, I would suggest placing a piece of parchment paper between the layers. When you are ready to serve, thaw in a single layer at room temperature until the frosting softens.
