It is a tried-and-true classic dessert beloved by many for its simplicity and pure deliciousness. Much like my Funfetti Sheet Cake, this moist yellow sheet cake features a rich, tender crumb, thanks to the generous amount of butter and eggs, which give it its characteristic yellow color. The addition of sour cream is a secret weapon for adding moisture and richness to cakes, making this recipe ultra-tender and luxurious. The cake is topped with a smooth and creamy chocolate buttercream frosting that is simple to whip together. You will love the buttery, slightly vanilla-flavored cake and the deep, rich chocolate frosting. You just can’t beat this classic combination!
Cake flour: I like to use cake flour in this recipe to help create a more fine, delicate crumb. It creates a light, soft texture, which I love! However, if you only have all-purpose flour, that works well too. It will still have a tender crumb! Sugar: You will need granulated sugar for this recipe. Oil & Butter: Unsalted butter adds richness and flavor to the cake and the oil keeps the cake moist. Make sure the butter is at room temperature for easy creaming with the sugar. Pro tip: For an even more rich yellow color, choose European-style butter. Eggs: They provide moisture and structure, and help the cake rise. Adding the extra yolks helps give the cake its beautiful yellow color. Also make sure the eggs are at room temperature. Vanilla Extract: Pure vanilla extract enhances the flavor of the cake. Baking Powder and Baking Soda: These leavening agents help the cake rise and become light and fluffy. Sour Cream: Sour cream adds moisture, richness, and tenderness to the cake. It’s a key ingredient for creating a moist and flavorful cake. Buttermilk: I recommend using full-fat buttermilk for the best flavor and texture. Frosting Ingredients: For the frosting, you’ll need butter, cocoa powder, salt, espresso powder, vanilla, powdered sugar, and heavy cream. Adjust the frosting ingredients to achieve your desired consistency and sweetness level. Add sprinkles on top for a fun & festive look!
Bring together the cake batter easily by beating the softened butter and sugar together, adding oil, vanilla, eggs, yolks, dry ingredients, and the buttermilk.
