What You’ll Need: Ingredients and Equipment
Before we dive in, let’s gather all the necessary ingredients and tools for both the cake and the frosting.
For the Cake (Vanilla Base):
- 1/4 cup (4 tablespoons) unsalted butter, softened
- 1/4 cup (50g) granulated sugar
- 1 large egg
- 1/2 teaspoon vanilla extract
- 1/2 cup (60g) all-purpose flour
- 1/4 teaspoon baking powder
- Pinch of salt
- 2 tablespoons milk
For the Buttercream Frosting:
- 1/4 cup (4 tablespoons) unsalted butter, softened
- 1 cup (120g) powdered sugar
- 1-2 tablespoons milk
- 1/4 teaspoon vanilla extract (optional)
- Food coloring (optional)
Essential Equipment:
- Small mixing bowl(s)
- Electric mixer (handheld or stand mixer) or whisk
- Measuring cups and spoons
- 4-inch round cake pan
- Parchment paper
- Small offset spatula or knife
- Piping bag and tips (optional, for decorating)
- Small turntable (optional, for easier decorating)
- Bento box or small container
Step 1: Get Ready to Bake – Preheat and Prep Your Pan
First things first, preheat your oven to 350°F (175°C). While the oven is heating, take your 4-inch round cake pan and grease it thoroughly with butter or cooking spray. To prevent the cake from sticking, lightly dust the greased pan with flour. For an extra layer of protection, cut a circle of parchment paper to fit the bottom of the pan and place it inside. This will make removing the cake a breeze.
Step 2: Creaming for Success – Combine Butter and Sugar
In a mixing bowl, add the softened unsalted butter and granulated sugar. Using an electric mixer (handheld or stand mixer) or a whisk, beat these two ingredients together until the mixture becomes light, fluffy, and pale yellow in color. This process, known as creaming, usually takes about 2-3 minutes. Make sure to scrape down the sides of the bowl occasionally to ensure everything is evenly incorporated. This step is crucial for a tender bento cake.
Step 3: Incorporating Wet Goodness – Add Egg and Vanilla
Now, crack the large egg into the bowl with the creamed butter and sugar. Beat until the egg is fully incorporated and the mixture is smooth. Next, add the vanilla extract. This simple ingredient adds a wonderful aroma and flavor to your cake. Stir it in until just combined.
Step 4: Whisking Away Lumps – Combine Dry Ingredients
In a separate small bowl, whisk together the all-purpose flour, baking powder, and salt. Whisking ensures that the baking powder and salt are evenly distributed throughout the flour, which helps the cake rise uniformly and have a balanced flavor.
Step 5: The Gentle Fold – Combining Wet and Dry
Now, it’s time to combine the wet and dry ingredients. Gradually add the dry ingredients to the wet ingredients in the mixing bowl. Mix on low speed if using an electric mixer, or gently fold the ingredients together with a spatula. Continue mixing until just combined. Be careful not to overmix the batter, as this can develop the gluten in the flour and result in a tough cake. A few streaks of flour are okay at this stage.
Step 6: Adding Moisture – Stir in the Milk
Pour the milk into the batter and stir until everything is smooth and well combined. The batter should now have a slightly thin consistency that is easily pourable.
Step 7: Into the Pan – Pour and Prepare for Baking
Carefully pour the cake batter evenly into the prepared 4-inch cake pan. Gently tap the pan on the countertop a few times to release any air bubbles trapped in the batter.
Step 8: Bake to Golden Perfection
Place the cake pan in the preheated oven and bake for 20-25 minutes. To check if the cake is done, insert a wooden skewer into the center. If it comes out clean with no moist batter clinging to it, the cake is ready. The top of the cake should also be lightly golden brown and spring back gently when touched.
Step 9: Cool Down Time – Before Frosting Fun
Once the cake is out of the oven, let it cool in the pan for 5-10 minutes. Then, gently invert the cake onto a wire rack and allow it to cool completely. It’s crucial that the cake is completely cool before you start frosting, otherwise the frosting will melt and slide off.
Step 10: Creamy Dream – Making the Buttercream Base
While the cake is cooling, let’s make the buttercream frosting. In a clean mixing bowl, beat the softened unsalted butter with an electric mixer until it becomes light and creamy. This will take about 2-3 minutes.
Step 11: Sweetening the Deal – Adding Powdered Sugar
Gradually add the powdered sugar to the creamed butter, one cup at a time. Start by mixing on low speed to prevent a cloud of sugar from erupting. Once most of the sugar is incorporated, increase the speed to medium and beat until the frosting becomes light, fluffy, and smooth.
Step 12: Perfecting the Consistency – Adding Liquid and Vanilla
Add 1 tablespoon of milk and the optional vanilla extract to the frosting. Beat until well combined. If the frosting seems too thick, add the remaining tablespoon of milk, a little at a time, until you reach your desired spreading or piping consistency.
Step 13: Adding a Pop of Color – Optional Frosting Fun
If you want to add a touch of personality to your bento cake, now is the time to color your frosting. Divide the buttercream into separate bowls if you want multiple colors. Add a few drops of food coloring to each bowl and mix well until you achieve your desired shade. Remember, you can always add more coloring drop by drop to deepen the color.
Step 14: Leveling for Smoothness – Optional Cake Prep
Once the cake is completely cool, you can optionally level it. Use a serrated knife to carefully trim off any domed top to create a flat and even surface for easier frosting.
Step 15: Sealing in Crumbs – The Crumb Coat
Place the cooled cake on a small plate or a turntable if you have one. Spread a thin, even layer of frosting over the top and sides of the cake. This is called the crumb coat, and its purpose is to trap any loose crumbs and create a smooth base for the final layer of frosting. Once the cake is crumb-coated, refrigerate it for 10-15 minutes to allow the frosting to firm up. This step helps prevent crumbs from mixing into your final layer of frosting.
Step 16: The Final Flourish – Frosting Your Bento Cake
Remove the chilled cake from the refrigerator and apply a second, thicker layer of buttercream frosting over the crumb coat. Use your small offset spatula or a knife to smooth the frosting as much as possible. A turntable can be helpful for achieving a smooth finish as you rotate the cake while holding the spatula steady.
Step 17: Unleash Your Creativity – Decorating Your Mini Masterpiece
Now for the fun part – decorating your bento cake! There are endless possibilities to make it unique and special. Here are a few ideas:
- Simple Swirls: Use your spatula to create elegant swirls on the top of the cake.
- Piping Magic: Fit a piping bag with your desired tip (star, round, petal, etc.) and fill it with colored frosting. Pipe borders around the edges, create delicate rosettes, write a sweet message, or add other intricate designs.
- Sprinkle Shower: Add a touch of whimsy with colorful sprinkles around the sides or sprinkled on top.
- Fruity Fun: Arrange slices of fresh berries
