Sweet Fluffy Cake: Just the name conjures up images of birthday celebrations, cozy afternoon teas, and pure, unadulterated joy, doesn’t it? I remember my grandmother always baking a sweet fluffy cake for every special occasion, and the aroma alone was enough to make my mouth water. It was a simple recipe, passed down through generations, and it always felt like a warm hug in dessert form.
While the exact origins of cake are debated, sweetened bread-like creations have existed for centuries across various cultures. The modern cake, as we know it, truly blossomed with the advent of refined sugar and reliable baking powder, allowing for the light and airy textures we crave. And what’s not to love? The delicate crumb, the melt-in-your-mouth sweetness, and the endless possibilities for customization make it a universally beloved treat.
People adore this type of cake for its comforting simplicity and versatility. It’s the perfect base for frosting, fruit, or simply enjoyed on its own with a dusting of powdered sugar. Plus, it’s relatively easy to make, making it a go-to recipe for both novice and experienced bakers alike. So, are you ready to create your own slice of happiness? Let’s get baking!

Ingredients:
- For the Cake:
- 2 ½ cups (300g) all-purpose flour, plus more for dusting
- 1 tablespoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup (2 sticks or 226g) unsalted butter, softened
- 1 ¾ cups (350g) granulated sugar
- 2 large eggs
- 2 large egg whites
- 1 teaspoon vanilla extract
- 1 ¼ cups (300ml) buttermilk, room temperature
- For the Vanilla Buttercream Frosting:
- 1 cup (2 sticks or 226g) unsalted butter, softened
- 3-4 cups (360-480g) powdered sugar, sifted
- ¼ cup (60ml) heavy cream
- 2 teaspoons vanilla extract
- Pinch of salt
Preparing the Cake Batter:
- Preheat and Prep: First things first, let’s get our oven ready! Preheat it to 350°F (175°C). While it’s heating up, grease and flour a 9×13 inch baking pan. I like to use a baking spray that already has flour in it for extra insurance against sticking. Trust me, nobody wants a cake that clings to the pan!
- Dry Ingredients Unite: In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Make sure everything is evenly distributed. This ensures that your cake rises properly and has a consistent texture. I usually whisk for about 30 seconds to a minute.
- Cream the Butter and Sugar: In a separate large bowl (or the bowl of your stand mixer), cream together the softened butter and granulated sugar until light and fluffy. This is a crucial step for creating a tender cake. It usually takes about 3-5 minutes on medium speed. You should see the mixture lighten in color and become noticeably fluffier. Don’t rush this step!
- Add the Eggs: Beat in the eggs one at a time, followed by the egg whites. Make sure each egg is fully incorporated before adding the next. After adding the eggs, stir in the vanilla extract. The vanilla really enhances the flavor of the cake.
- Alternate Wet and Dry: Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk. Begin and end with the dry ingredients. I usually add about a third of the dry ingredients, then half of the buttermilk, then another third of the dry ingredients, then the remaining buttermilk, and finally the last of the dry ingredients. Mix until just combined. Be careful not to overmix the batter, as this can lead to a tough cake. A few streaks of flour are okay.
- Pour and Bake: Pour the batter into the prepared baking pan and spread it evenly. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. The baking time may vary depending on your oven, so keep an eye on it.
- Cool Completely: Once the cake is done, remove it from the oven and let it cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely. Make sure the cake is completely cool before frosting, or the frosting will melt.
Making the Vanilla Buttercream Frosting:
- Cream the Butter: In a large bowl (or the bowl of your stand mixer), beat the softened butter until smooth and creamy. This usually takes about 2-3 minutes on medium speed.
- Add the Powdered Sugar: Gradually add the sifted powdered sugar, one cup at a time, beating well after each addition. Sifting the powdered sugar helps to prevent lumps in the frosting. If the frosting seems too thick, add a tablespoon of heavy cream at a time until it reaches your desired consistency.
- Add the Heavy Cream and Vanilla: Beat in the heavy cream, vanilla extract, and salt until the frosting is light and fluffy. This usually takes about 1-2 minutes on high speed. Taste and adjust the sweetness or vanilla extract as needed.
Assembling and Frosting the Cake:
- Level the Cake (Optional): If your cake has a domed top, you can use a serrated knife to level it off. This will make it easier to frost. I usually don’t bother unless the dome is really pronounced.
- Frost the Cake: Place the cooled cake on a serving platter or cake stand. Using an offset spatula, spread the vanilla buttercream frosting evenly over the top of the cake. You can create swirls or a smooth finish, depending on your preference.
- Decorate (Optional): If you want to get fancy, you can decorate the cake with sprinkles, fresh berries, chocolate shavings, or any other toppings you like. I sometimes add a border of frosting around the edges using a piping bag and a decorative tip.
- Chill (Optional): For best results, chill the frosted cake in the refrigerator for at least 30 minutes before serving. This will help the frosting to set and make the cake easier to slice.
- Serve and Enjoy: Slice the cake and serve. This sweet fluffy cake is perfect for birthdays, holidays, or any special occasion! Enjoy!
