Making a Basic All-In-One Sheet Cake is one of the easiest ways to bake a delicious dessert without much effort. I love this recipe because you can mix everything in one bowl, and the cake always comes out light and fluffy. It’s perfect for casual family gatherings or when you just want something sweet without spending too much time in the kitchen. Plus, you probably have most of the ingredients in your pantry already.
Ingredients
For the cake:
- 1 cup + 2 tablespoons (230g) granulated sugar
- 1 cup + 1 tablespoon (230g) butter, straight from the fridge
- 2 ½ cups (290g) all-purpose flour
- 1 teaspoon salt
- 4 ½ teaspoons baking powder
- 4 extra-large eggs
- 5 tablespoons milk
To finish:
- A little sifted confectioners’ sugar (optional)
Instructions
- Preheat the oven to 350°F (180°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper.
- In a large mixing bowl, add the butter and sugar. Beat them together until the mixture becomes light and fluffy.
- Crack the eggs into the bowl one at a time, beating well after each addition.
- Sift the flour, baking powder, and salt together in a separate bowl. Gradually add this dry mix into the wet ingredients, stirring gently to combine.
- Pour in the milk and stir until the batter is smooth and creamy. Make sure not to overmix.
- Pour the batter into the prepared baking pan and spread it evenly with a spatula.
- Bake for about 30–35 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.
- Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
- Once cooled, dust with a little sifted confectioners’ sugar if you like.

Keep an eye on the cake while baking to avoid overbrowning.If you love simple and delicious desserts like this sheet cake, you’ll definitely want to try Chocolatines — rich, buttery pastries with a decadent chocolate filling that melt in your mouth.
