Why You’ll Love This Recipe

These mini cake slices strike the perfect balance between elegance and excitement. The sponge is light and subtly earthy from the matcha (or bright and citrusy with lemon zest), while the orange-scented mascarpone cream brings a creamy tang. But the real showstopper is the flame buttercream—swirled in red, orange, and yellow, it turns each slice into a visual tribute to Aries’ fiery nature. They’re beautiful to serve, easy to share, and totally unforgettable.

Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the Sponge Cake:

• eggs
• granulated sugar
• all-purpose flour
• matcha powder (or lemon zest)
• salt
• vanilla extract

For the Citrus Whipped Cream Filling:

• heavy cream
• mascarpone cheese
• powdered sugar
• orange zest
• vanilla extract
• mandarin orange segments (peeled and patted dry)

For the Flame Buttercream Swirl:

• unsalted butter, softened
• powdered sugar
• heavy cream
• gel food coloring: red, orange, yellow
• optional: gold luster dust

To Garnish & Wrap:

• mandarin slices
• yellow jelly cubes or fruit gelée
• rosemary sprigs or golden berries
• clear food-safe wrap or parchment + twine

Directions

Make the Sponge Cake:
Preheat the oven to 350°F (175°C). Line a sheet pan with parchment paper.
In a mixing bowl, beat the eggs and sugar on high speed until thick, pale, and ribbon-like (about 5 minutes).
Sift in the flour, matcha powder (or lemon zest), and salt. Add vanilla extract. Gently fold everything together until just combined.
Pour the batter evenly into the sheet pan and smooth the top. Bake for 10–12 minutes, until lightly golden and springy to the touch.
Cool completely, then cut into neat rectangular slices.

Make the Citrus Cream:
Whip the heavy cream until soft peaks form. In a separate bowl, beat mascarpone with powdered sugar, orange zest, and vanilla extract until smooth.
Gently fold the whipped cream into the mascarpone mixture. Chill until ready to use.

Make the Flame Buttercream:
Beat softened butter until fluffy and light. Gradually add powdered sugar and cream until smooth and spreadable.
Divide into three small bowls. Tint one with red gel coloring, one with orange, and one with yellow.
Swirl the colors together gently with a spatula to create a flame effect—do not overmix. Transfer to a piping bag fitted with a star tip.

Assemble the Mini Slices:
Layer sponge cake, a generous dollop of citrus mascarpone cream, and mandarin slices. Repeat for 2–3 layers depending on desired height.
Frost the top and sides with the flame buttercream, piping in swooping, swirling motions to create a bold flame pattern.

Garnish & Wrap:
Top each slice with a few yellow jelly cubes, a segment of mandarin, and a small rosemary sprig or golden berry.
Wrap individually in clear food-safe wrap or parchment and tie with twine for a giftable, ready-to-serve presentation.
