Ready to bake? Let’s get into the nitty-gritty of making this delightful Cake. Trust me, it’s easier than you think!
Gather Your Tools
You’ll need a large mixing bowl, a whisk or hand mixer, a 9×13-inch sheet pan, and parchment paper for easy cleanup. Also, remember to use a cooling rack and a spatula to spread the frosting later.
Preheat Your Oven
Set your oven to 350°F (175°C). Grease your sheet pan or line it with parchment paper to prevent sticking. If you’re feeling fancy, dust the greased pan with a light flour coating for extra protection.
Mix the Wet Ingredients
Mix the Kefir, sugar, eggs, melted butter (or oil), and vanilla extract in a large bowl. The mixture should be smooth and creamy. Use room-temperature eggs for effortless blending.
Sift the Dry Ingredients
Sift the flour, baking powder, baking soda, and salt in another bowl. This step ensures no lumps and gives the Cake a consistent texture. If you don’t have a sifter, a fine-mesh strainer works just as well.
Combine Wet and Dry Ingredients
Slowly add the dry ingredients to the wet mixture, stirring gently until combined Be careful not to overmix, as this can make the Cake dense A few small lumps in the batter are okay; they’ll bake out.
Pour and Bake
Pour the batter into your prepared sheet pan. Smooth the top with a spatula and pop it into the oven. Bake for 25–30 minutes or until a toothpick inserted in the center comes clean. Pro tip: Rotate the pan halfway through baking for even cooking.
Cool and Frost
Let the Cake cool entirely before adding the frosting. Trust me, patience pays off here. A warm cake will melt the frosting; no one wants a runny mess.

Chocolate Ganache
Melt dark chocolate with heavy cream for a rich, decadent finish. Sprinkle a pinch of sea salt on top for contrast.

FAQs About Tangy Sheet Cake Recipe
What is the difference between sheet cake and Cake?
The main difference between sheet cakes and other cakes is their size and shape. A sheet cake is baked in a large, flat, rectangular pan, like a 9×13-inch or bigger pan. It usually has just one layer, making cutting into squares or rectangles easy. This makes it great for feeding a crowd.
Other cakes, like round or bundt cakes, can be different shapes and often have multiple layers. They’re usually more decorative, with fancy designs or tiered structures. On the other hand, sheet cakes are simpler and frequently topped with basic frosting or a glaze, keeping them easy and fuss-free.
How many boxes of cake mix for a half-sheet cake?
A half-sheet cake usually requires 2-3 boxes of cake mix, depending on how thick you want. For a 12×18-inch pan, two boxes will make a thinner layer, while three boxes will create a denser cake. Check the instructions on your cake mix box and the span size to avoid overflow while baking.
How do you bake a half-sheet cake?
Baking a half-sheet cake is simple with these steps :
Prepare Your Pan: Use a 12×18-inch half-sheet pan. Grease it thoroughly or line it with parchment paper to prevent sticking.
Preheat the Oven: Follow the recipe or cake mix instructions to set the temperature at 325–350°F.
Mix Your Batter: Whether using a homemade recipe or a boxed mix, ensure the batter is smooth and lump-free.
Pour the batter evenly into the pan to ensure the Cake bakes uniformly.
Baking: Place the pan in the center of the oven. Start checking for doneness at the minimum recommended time—most half-sheet cakes bake in about 25–30 minutes. Insert a toothpick in the center; the Cake is ready if it comes out clean.
Cool and Frost To prevent the frosting from melting, allow the cake to cool completely in the pan before frosting or decorating it.
Why is sheet cake so good?
Sheet cakes are loved for being straightforward and versatile. They’re easy to bake and decorate and perfect for serving a crowd. Their flat, single-layer design means they bake and cool quickly, making them great for last-minute events or casual gatherings. The even shape ensures every slice looks the same, with no uneven layers or messy edges. Plus, you can customize them with different flavors and toppings, making them a hit for any occasion!
Do sheet cakes have two layers?
Sheet cakes are usually single-layered, which makes them simple and convenient. They are also faster and easier to frost and serve, but you can make a double-layer sheet cake if you want a more impressive dessert. Just bake two sheet cakes of the same size, add a layer of frosting or filling between them, and frost the outside as usual. Remember, a double-layer sheet cake will be taller and need extra frosting and support to keep it stable.
Will a half-sheet pan fit in a standard oven?
Yes, a half-sheet pan will fit in most standard home ovens. A half-sheet pan is typically 12×18 inches, which is the perfect size for many ovens. However, if your oven is compact or has smaller-than-usual racks, you’ll want to measure first to make sure. If you find a half-sheet pan too large, you can use two smaller quarter-sheet pans instead, which will still give you the same amount of Cake.
