(Makes one 4-inch bento cake)

For the Cake

• 4 tbsp all-purpose flour: Swap with gluten-free flour (like King Arthur’s 1:1 blend) for dietary needs. The low ratio protein content ensures a tender crumb.
• 3 tbsp granulated sugar: Adjust to taste or use coconut sugar for a caramel-like flavor.
• 1 large egg: Substitute with a flax egg (1 tbsp ground flaxseed + 3 tbsp water) for vegan cakes. The flax egg binds the batter without altering taste.
• 2 tbsp milk: Dairy or plant-based (almond, oat) work equally well. Almond milk adds a nutty undertone.
• 1 tbsp neutral oil: Vegetable, coconut, or avocado oil prevents dryness. Avoid olive oil—its strong flavor overpowers vanilla.

• ¼ tsp vanilla extract: Enhances flavor; try almond or lemon extract for variety.

For the Frosting

• ½ cup unsalted butter: Softened to room temperature. Use vegan butter (like Miyoko’s) for dairy-free options.
• 1 cup powdered sugar: Sifted to avoid lumps. If you’re out, blend granulated sugar in a spice grinder.
• 1 tsp milk: Adjust for desired consistency. Add more for a spreadable texture or less for stiff peaks.

Optional Decorations

• Edible glitter, sprinkles, fresh berries, or fondant shapes. Fondant (like Satin Ice) can be molded into stars, hearts, or letters.
