"Design a futuristic building shaped like a multi-layered cake. The structure should have several stacked, rounded tiers one smaller above the bigger one, each with different textures and materials that evoke a sense of elegance and festivity. The edge of the rounded elements must contain pillar structure similar to candles. The exterior should be well lighted and resemble a decadent cake with frosting-like smooth surfaces, edible-looking elements like sugar crystals, and soft pastel colors, including pinks, blues, and whites. The top layer should feature a decorative cherry or a similar accent or a star decoration. The overall design should blend whimsy and modern architecture, with large windows resembling sugar glaze and architectural elements like pillars or stairs that suggest layers of a cake. Incorporate whimsical lighting to make the building appear like it's glowing with a celebratory ambiance, evoking the joy and charm of a birthday or wedding cake".Add candles like structure on top of the building to light up environment.
