I can’t get over how these vibrant buttercream blooms turn a simple cake into the showstopping centerpiece every celebration deserves. One slice of this floral beauty and the whole dessert table feels instantly unforgettable.

I’m obsessed with this flower decorated cake because it’s dramatic without being stiff. The buttercream blooms look like they belong in a fancy bakery window, but the whole thing still feels fun, bold, and a little extra.

I love the way pure vanilla extract gives the cake that clean, sweet flavor underneath all the color. And the gel food coloring makes every petal pop, from soft blush roses to loud little daisies.

But the best part? Slicing into something this pretty and getting actual tender cake, not just a photo prop.

This is the cake I want at every celebration.

Ingredient Quantities

2 1/2 cups (312 g) all purpose flour

2 1/2 teaspoons baking powder

1/2 teaspoon fine salt

1 cup (226 g) unsalted butter, softened

2 cups (400 g) granulated sugar

4 large eggs, room temperature

1 tablespoon pure vanilla extract

1 cup (240 ml) whole milk, room temperature

1/2 cup (120 ml) simple syrup (equal parts sugar and water), optional for brushing layers

1 1/2 cups (340 g) unsalted butter, softened, for buttercream

8 cups (960 g) powdered sugar, sifted

1/4 cup (60 ml) heavy cream or whole milk, more if needed

Gel food coloring, assorted colors for flowers

2 to 4 tablespoons meringue powder or powdered egg whites, optional for stiffer piping consistency

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350°F (175°C). Grease and line two 8 or 9 inch round cake pans with parchment and set aside.

2. Whisk together 2 1/2 cups (312 g) all purpose flour, 2 1/2 teaspoons baking powder, and 1/2 teaspoon fine salt in a bowl.

3. In a large bowl, cream 1 cup (226 g) softened unsalted butter with 2 cups (400 g) granulated sugar until light and fluffy, about 3 to 5 minutes. Add 4 room temperature eggs one at a time, beating well after each. Stir in 1 tablespoon pure vanilla extract.

4. With mixer on low, add the dry ingredients in three additions alternating with 1 cup (240 ml) room temperature whole milk, beginning and ending with the dry ingredients. Scrape bowl and mix until just combined.

5. Divide batter evenly between prepared pans and smooth tops. Bake 25 to 30 minutes or until a toothpick inserted in the center comes out clean. Cool in pans 10 minutes, then invert onto wire racks to cool completely.

6. For the buttercream, beat 1 1/2 cups (340 g) softened unsalted butter until creamy. Gradually add 8 cups (960 g) sifted powdered sugar on low speed. Add 1/4 cup (60 ml) heavy cream or whole milk, 2 teaspoons vanilla extract, and 1/2 teaspoon fine salt; increase speed and beat until light and fluffy. If you want stiffer piping consistency, add 2 to 4 tablespoons meringue powder or powdered egg whites and beat until incorporated. Adjust cream or sugar to reach desired stiffness.

7. Level cake layers if needed. Optionally brush each layer with 1/2 cup (120 ml) simple syrup to add moisture. Place one layer on a cake board or plate and spread an even layer of buttercream. Top with second layer and apply a thin crumb coat of buttercream around the cake. Chill 20 to 30 minutes until firm.

8. Divide remaining buttercream into small bowls and tint with gel food coloring to create vibrant flower colors and greens for leaves. Transfer each color to piping bags fitted with appropriate tips for roses, chrysanthemums, daisies, petals, and leaves. Use a flower nail and parchment squares to pipe flowers first if you prefer to make flowers ahead.

9. Pipe flowers directly onto the chilled cake or adhere pre piped flowers by placing a dab of buttercream under each. Fill gaps with smaller blooms and leaves, and smooth or texture remaining surface as desired.

10. Chill the finished cake briefly to set the buttercream, then bring to room temperature before serving. Store leftovers covered in the refrigerator for up to 4 days.

FAQ

Q: Can I make this cake gluten free? A: Yes. Substitute a 1-to-1 gluten free flour blend that includes xanthan gum and weigh ingredients for best results. Bake times may be a few minutes longer and texture will be slightly different.

Q: How do I prevent the layers from drying out? A: Brush cooled layers lightly with the optional simple syrup. Store frosted cake at room temperature for up to 24 hours or refrigerate and bring to room temperature before serving.

Q: My buttercream is too soft. How do I firm it up? A: Chill the buttercream 10 to 20 minutes, then rewhip. For stiffer piping, add 1 to 2 tablespoons of sifted powdered sugar or 1 to 2 tablespoons of meringue powder, then beat until smooth.

Q: How do I get bright, consistent colors for the piped flowers? A: Use concentrated gel colors in small amounts, mix thoroughly, and test on a plate. Start with less color and add more to reach the desired shade. For precise tones, tint separate small batches for each color.

Q: Can I make the cake and buttercream ahead of time? A: Yes. Bake layers 1 to 2 days ahead and wrap tightly. Buttercream keeps well refrigerated up to 5 days or frozen up to 1 month. Bring both to room temperature before assembling and rewhip the buttercream if needed.

Q: What piping tips and consistency are best for flowers? A: Use petal tips like #101 or #125 for roses and ruffled petals, and star or drop flower tips for simpler blooms. For petals, use a slightly stiffer buttercream that holds edges but still squeezes smoothly.

Flower Decorated Cake Recipe Substitutions and Variations

All purpose flour
- Cake flour substitute: for each cup AP flour, remove 2 tablespoons flour and replace with 2 tablespoons cornstarch, sift together
- Whole wheat pastry flour: replace up to 25 percent of AP flour for a nuttier flavor, expect slightly denser crumb
Unsalted butter (cake)
- Neutral oil for cake: use 3/4 cup oil per 1 cup butter by volume, keeps cake moist but changes texture and flavor
- Applesauce: replace up to half the butter by volume for reduced fat and added moisture
Unsalted butter (buttercream)
- Vegetable shortening: 1:1 replacement for firmer, more stable buttercream; add vanilla or butter extract for richer flavor
- Stabilized cream cheese: replace up to half the butter for tangy, softer frosting; refrigerate for stability
Powdered sugar
- Make your own: blend granulated sugar to a powder and add 1 tablespoon cornstarch per cup to prevent clumping
- Confectioners’ sugar from store: direct 1:1 swap if recipe calls for powdered sugar
Eggs
- Flax egg: 1 tablespoon ground flaxseed + 3 tablespoons water per egg, set 5 minutes; good for binding in cakes
- Commercial egg replacer: follow package substitution for 1:1 replacement, works well for structure without egg flavor

Pro Tips

1) Measure the flour with a spoon and level it. Scooping straight from the bag packs flour and gives a dense crumb. A light, aerated flour measurement keeps the cake tender.

2) Get the butter and eggs truly at room temperature. Softened butter creams up fluffier and room temperature eggs incorporate faster so your batter stays airy. If the butter is too cold, give it a few seconds in the microwave at very low power rather than overworking it.

3) When you add the eggs, add them one at a time and scrape the bowl between additions. That small pause keeps the emulsion stable so the cake rises evenly and the texture stays smooth.

4) For piping, make small practice flowers on parchment first. Chill them briefly to set, then transfer to the cake. If you need stiffer petals, add 1 to 2 tablespoons meringue powder at a time until the buttercream holds shape, but be careful not to overdry the icing.

5) Brush layers lightly with simple syrup and always bring the finished cake to room temperature before slicing. The syrup keeps the inside moist and the buttercream tastes best when not straight from the fridge.
