Ingredients
For the cake:

- 1 teaspoon baking powder
- 1 pinch of salt
- 2 large eggs
- ½ cup granulated sugar
- ½ cup unsalted butter, softened

How to Make Buttercream Bento Cake?
Begin by preheating the oven to 175°C and preparing two 4-inch round cake pans with grease and parchment paper. In a small bowl, whisk together the flour, baking powder, and salt to ensure even distribution and a light texture. In a separate bowl, beat the eggs with granulated sugar until pale and fluffy, forming the base for a soft sponge. Incorporate softened butter and vanilla extract to the mixture for added richness and aroma, then gently fold in the dry ingredients alternately with milk until a smooth, silky batter forms.
Divide the batter evenly between the prepared pans and bake until a toothpick inserted into the center comes out clean. Allow the cakes to cool completely before frosting. Whip the softened butter for the buttercream until creamy, gradually adding powdered sugar along with cream and vanilla to achieve a light, fluffy consistency. Assemble the cake by layering one sponge, applying a thin coating of buttercream, placing the second layer on top, and covering with a crumb coat. After chilling briefly, apply a smooth final coat for a refined, minimalist finish, enhanced subtly with pastel hues or delicate piping.
