• ¾ cup granulated sugar
• ½ cup unsalted butter, softened
• 2 large eggs, room temperature
• 1 teaspoon vanilla extract
• ¾ cup whole milk, room temperature
• For the Buttercream:
• 1 cup unsalted butter, softened
• 3-4 cups powdered sugar, sifted
• 1-2 tablespoons heavy cream or whole milk

How to Make Bento Cake

Get ready to whisk, mix, and decorate your way to the most charming little cakes. Follow these steps, and don’t be afraid to let your creativity shine!

1. Prepare Your Cake Layers: Preheat your oven to 350°F (175°C). Grease and flour two 4-inch round cake pans or a small baking sheet (about 9×13 inches) for cutting out rounds.
2. Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar with an electric mixer until light and fluffy, about 2-3 minutes.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
5. Alternate Wet and Dry: Gradually add the dry ingredients to the wet ingredients in three additions, alternating with the milk in two additions. Begin and end with the dry ingredients. Mix until just combined, being careful not to overmix.
6. Bake the Cakes: Pour the batter evenly into your prepared 4-inch pans, or spread it onto your baking sheet. Bake for 20-25 minutes for the small pans, or 12-15 minutes for the sheet, or until a toothpick inserted into the center comes out clean.
7. Cool Completely: Let the cakes cool in their pans for 10 minutes before inverting them onto a wire rack to cool completely. If using a sheet cake, let it cool completely before using a 4-inch cookie cutter (or a small bowl as a guide) to cut out your cake rounds.
8. Make the Buttercream: While the cakes cool, beat the softened butter in a large bowl with an electric mixer until creamy. Gradually add the sifted powdered sugar, alternating with the heavy cream/milk and vanilla extract. Beat on high speed until light, fluffy, and smooth, about 3-5 minutes. Add a pinch of salt to balance the sweetness.
9. Level and Stack: Once cakes are fully cooled, use a serrated knife to level the tops if needed. Place one cake layer on your serving plate or a small cake board. Spread a thin layer of buttercream over the top. Add the second cake layer and repeat.
10. Crumb Coat: Apply a very thin layer of buttercream over the entire cake. This is your “crumb coat” and helps to trap any loose crumbs. Chill in the refrigerator for 15-20 minutes until set.
11. Final Frost and Decorate: Apply a thicker, even layer of buttercream over the chilled crumb-coated cake. Use a small offset spatula or butter knife to smooth the sides and top. Now comes the fun part! Tint small portions of your remaining buttercream with gel food coloring if desired. Use a piping bag with a small round tip to write messages, draw designs, or add cute details. Finish with sprinkles for an extra touch of sparkle!

Fun Twists & Serving Ideas

Bento Cakes are canvases waiting for your imagination! Here are a few ideas to spark your creativity and delight your taste buds:

• Chocolate Lover’s Dream: Swap out 1/4 cup of flour for cocoa powder in the cake batter, and use a rich chocolate buttercream or ganache for frosting.
• Lemon Zest Brightness: Add 2 tablespoons of fresh lemon zest to your cake batter and a squeeze of lemon juice to your buttercream for a bright, refreshing flavor.
• Red Velvet Romance: Follow your favorite red velvet cake recipe, bake in small rounds, and pair it with a tangy cream cheese frosting. Adorn with edible glitter for a touch of elegance.
• Fruity Fillings: Between your cake layers, add a thin layer of fruit jam, fresh berry compote, or a delicate lemon curd for an extra burst of flavor and texture.
• Themed Celebrations: Decorate your Bento Cakes to match a specific occasion – tiny birthday candles for a mini celebration, pastel colors for a baby shower, or spooky designs for Halloween treats.

“I made these for my daughter’s birthday, and they were an absolute hit! So much easier than a big cake, and everyone loved having their own personalized mini cake. The cake was so moist, and the buttercream was heavenly. I added a little raspberry jam in the middle – divine!”

David L. ⭐️⭐️⭐️⭐️⭐️
“My girlfriend is obsessed with K-dramas, so I made her a Bento Cake with a cute little message. It was surprisingly simple, and her reaction was priceless! It looked exactly like the ones online. Definitely making these again for special occasions.”

“These are my new go-to for thoughtful gifts. I’ve done a vanilla bean and a chocolate version, and both turned out perfectly. They transport well, and the small size makes them feel so special. A true joy to bake!”

FAQ

Got questions about these adorable cakes? We’ve got answers!

Q: What if I don’t have small cake pans?
A: No worries! You can bake a regular-sized sheet cake (like a 9×13 inch) and then use a 4-inch round cookie cutter or even a small bowl as a guide to cut out your cake rounds once it’s cooled. You’ll likely get 2-4 rounds, depending on the size of your cutter.

Q: Can I make the cake layers ahead of time?
A: Absolutely! Baked and cooled cake layers can be wrapped tightly in plastic wrap and stored at room temperature for up to 2 days, or frozen for up to 2 weeks. Thaw completely before frosting.

Q: How should I store Bento Cakes?
A: Once frosted, Bento Cakes are best stored in an airtight container in the refrigerator for up to 3-4 days. Let them come to room temperature for about 20-30 minutes before serving for the best texture and flavor.

Q: What kind of frosting is best for Bento Cakes?
A: A stable buttercream is ideal for piping and decorating. American buttercream (like in this recipe) or Swiss/Italian meringue buttercreams work beautifully. Cream cheese frosting is also delicious but can be a bit softer to pipe intricate details.

Conclusion

There’s something truly magical about these miniature marvels. Bento Cakes aren’t just desserts; they’re tiny expressions of love, celebration, and pure, unadulterated joy. Whether you’re crafting one for a cherished friend, a family milestone, or simply to brighten your own day, the process is as rewarding as the first delightful bite. Embrace the creativity, savor the tender crumb, and watch as these little cakes bring big smiles to every face. So go on, whisk up some batter, pipe some dreams, and let the warmth of your kitchen fill with the sweet promise of a perfect Bento Cake. Happy baking, dear friends!

Recipe Note

For the cleanest cuts when leveling your cake layers, chill them in the refrigerator for about 15-20 minutes. A slightly firm cake is much easier to work with and minimizes crumbs when frosting!

Bento Cake

Ingredients

• 1/2 cup all-purpose flour
• 1/4 cup granulated sugar
• 1/2 teaspoon baking powder
• Pinch of salt
• 1/4 cup milk (whole or low-fat)
• 2 tablespoons vegetable oil
• 1/2 teaspoon vanilla extract
• 1 small egg (or 1/2 of a large egg)
• For the Buttercream Frosting:
• 1/4 cup (1/2 stick) unsalted butter, softened
• 1 cup powdered sugar (confectioners’ sugar)
• 1/2 teaspoon vanilla extract
• 1-2 tablespoons milk or heavy cream (as needed for consistency)
• Optional: Food coloring for frosting

Instructions

1. Preheat your oven to 350°F (175°C). Grease and flour a 4-inch round cake pan, or line with parchment paper.
   2. In a medium bowl, whisk together the flour, granulated sugar, baking powder, and salt.
   3. In a separate small bowl, whisk together the milk, vegetable oil, vanilla extract, and egg.
   4. Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix.
   5. Pour the batter into the prepared cake pan. Bake for 20-25 minutes, or until a wooden skewer inserted into the center comes out clean.
   6. Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
   7. While the cake cools, prepare the buttercream frosting: In a mixing bowl, beat the softened unsalted butter until creamy. Gradually add the powdered sugar, mixing on low speed until combined, then increase speed to medium and beat until fluffy.
   8. Add the vanilla extract and 1 tablespoon of milk or cream. Beat until smooth. If the frosting is too thick, add more milk/cream, 1 teaspoon at a time, until desired consistency is reached. (Optional: Mix in a few drops of food coloring if desired).
   9. Once the cake is completely cool, use a serrated knife to level the top if necessary. You can also slice the cake in half horizontally to create two layers, but for a bento cake, a single layer is common.
   10. Apply a thin crumb coat of frosting all over the cake and refrigerate for 10-15 minutes to set.
   11. Apply the remaining frosting, smoothing the sides and top. Decorate as desired with simple designs, text, or sprinkles.
   12. Serve immediately or store in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days.

Chef’s Notes: Bento cakes are miniature cakes, perfect for a single serving or small celebration. They are usually decorated simply and presented in a small box, mimicking the ‘bento’ meal concept. Feel free to customize the cake flavor (e.g., chocolate) or frosting color to your liking.
