Naked Layer Cake with Fruit and Flowers

Before you start

A naked cake shows its layers through a scraped veil of buttercream instead of hiding them under a thick, smooth coat. It looks relaxed, but it is actually less forgiving than a fully frosted cake: every uneven layer, crumb and gap is on display, and exposed sponge dries out faster. The work happens in leveling, a cold crumb coat and a firm scrape.

This build uses three 20 cm (8 in) vanilla butter layers, a light syrup to keep the exposed edges moist, and American buttercream. Decide on your decorations early. Berries and figs can go on the day, but cut flowers need preparation so that no stem or chemical residue touches the cake.

Ingredients

• Vanilla layers420 g (3½ cups, spooned and leveled) all-purpose flour
• 4 tsp baking powder
• 1 tsp fine salt
• 225 g (1 cup) unsalted butter — softened
• 400 g (2 cups) granulated sugar
• 4 large eggs — room temperature
• 1 tbsp vanilla extract
• 360 ml (1½ cups) whole milk — room temperature
• 60 ml (¼ cup) neutral oil
• Soaking syrup50 g (¼ cup) granulated sugar
• 60 ml (¼ cup) water
• Buttercream340 g (1½ cups) unsalted butter — softened
• 560 g (4½ cups) powdered sugar — sifted
• 3 to 4 tbsp heavy cream
• 2 tsp vanilla extract
• ⅛ tsp fine salt
• Decoration300 g (about 2 cups) mixed berries, figs or cherries — washed and patted completely dry
• 1 small bunch edible or food-safe flowers — see safety note

Method

1. Heat the oven to 175°C (350°F). Grease the pans, line the bottoms with parchment and grease again.
2. Whisk the flour, baking powder and salt. Beat the butter and sugar on medium-high for 4 minutes until pale. Add the eggs one at a time, then the vanilla. Combine the milk and oil in a jug.
3. On low speed, add the flour in three parts alternating with the milk mixture in two, mixing only until smooth. Divide the batter among the pans, about 560 g each.
4. Bake for 25 to 30 minutes, until the centers spring back and a toothpick comes out clean. Cool in the pans for 10 minutes, turn out and cool completely, about 1½ hours. For neater cutting, wrap and chill the layers for an hour or overnight.
5. Simmer the syrup sugar and water until dissolved, then cool. Beat the buttercream butter for 3 minutes until pale, add the powdered sugar and salt on low, then beat in the vanilla and enough cream for a soft but spreadable texture.
6. Level each layer with the serrated knife so all three tops are flat. Brush the cut surfaces lightly with syrup; the layers should look damp, not wet.
7. Fix the first layer to the board with a dab of buttercream. Spread about 1 cm (⅜ in) of buttercream on it, add the second layer, repeat, then set the last layer cut-side down so the top is crisp and flat.
8. Cover the whole cake with a thin crumb coat and scrape it smooth with the bench scraper. Chill for 30 minutes until firm.
9. Apply a second thin layer around the sides. Hold the scraper upright against the cake and turn the turntable in one smooth motion, scraping away until the sponge shows through in places. Smooth the top and chill for 30 minutes.
10. Prepare flowers that are not certified edible: wrap each stem in floral tape or insert it into a posy pick so no part of the plant goes into the cake. Arrange the fruit and flowers on the day of serving.

Tips for success

• Clean the scraper after every pass. Crumbs dragged back onto the cake are what make naked cakes look messy rather than rustic.
• Leveled, chilled layers are easier to stack straight. If the cake starts to lean, chill it for 15 minutes before adding more buttercream.
• Put fruit on as close to serving as you can. Cut fruit weeps juice into buttercream within a few hours; whole berries keep their shape longer.

Substitutions

American buttercream

Swiss meringue buttercream is less sweet and scrapes to a silkier finish. Use about 900 g. It softens faster in a warm room, so keep the cake cool.

Whole milk

Buttermilk gives a slightly more tender, tangy layer. Replace 1 tsp of the baking powder with ½ tsp baking soda to balance the acid.

Three 20 cm pans

Bake two deeper 20 cm layers for 35 to 40 minutes and torte each in half for a four-layer cake. Check doneness carefully; deep layers can sink if underbaked.

Variations

Lemon and berry naked cake

Add the finely grated zest of 2 lemons to the sugar before creaming and use lemon juice in place of half the syrup water. Fill with buttercream and a thin layer of lemon curd inside a buttercream dam.

Taller tiered look

Make the recipe twice for a 15 cm (6 in) tier and a 23 cm (9 in) tier. Support the lower tier with dowels and a cake board under the top tier.

Troubleshooting

Exposed edges look dry by serving time

Brush the layers with syrup before stacking, and assemble no more than a day ahead. Keep the cake loosely covered in the fridge until it goes out.

Crumbs streak the final coat

The crumb coat was skipped or not chilled enough. Scrape it thin, chill until firm, then apply the final layer with a clean scraper.

Cake bulges at the filling lines

The filling was too thick or too soft and the weight of the top layer squeezed it out. Keep each filling layer about 1 cm thick and chill between steps.

Buttercream is gritty or too stiff to scrape

Sift the powdered sugar and add cream a teaspoon at a time. Beat for a further minute; it should hold a peak but spread easily.

Storage

Keep the finished cake refrigerated, loosely covered, for up to 3 days, and let it stand at room temperature for about 1 hour before serving so the buttercream softens. Once fruit is added, serve within a few hours and refrigerate leftovers. Undecorated layers, wrapped well, freeze for up to 2 months.

Safety notes

Not all flowers are safe to eat, and florist flowers are often treated with pesticides. Use flowers sold as edible or food-grade, or keep stems sealed in floral tape or posy picks and remove them before cutting. Do not taste raw batter. Contains wheat, egg and milk.
