How to Make Bento Cake (Simple & Delicious!) Recipe
Step 1: Preparing the Cakes
Start by prepping your baking pan with cooking spray, then carefully press parchment paper into every corner so your cake doesn’t stick. Pour in the prepared cake mix batter and smooth it evenly with a spatula. This even layer is key for perfect slices later.
Step 2: Baking and Cooling
Bake your cake at 350 degrees Fahrenheit for 20-24 minutes until the top turns a light golden brown and a toothpick comes out clean. Let it cool completely, then loosen the edges with a butter knife and flip the pan to release the cake. The gentle flip is like unveiling a fresh canvas for frosting!
Step 3: Making the Buttercream Frosting
Whip the softened butter on medium speed until smooth, then add vanilla extract for that inviting aroma. Gradually mix in powdered sugar in halves, adding heavy cream partway through to achieve a silky texture. Continue mixing on low speed until everything comes together into a fluffy, dreamy frosting that’s just begging to be spread.
Step 4: Assembling Your Bento Cakes
Use a 6-inch biscuit cutter to create a dozen perfect cake circles from your baked sheet. Layer each one on a parchment square with a touch of buttercream underneath so they don’t slip during decorating. Drizzle each layer with a teaspoon of simple syrup before frosting for extra moistness. Start by spreading frosting between layers, then crumb coat the whole cake and chill to set. Apply a final thicker coat of buttercream and smooth it out, making your mini cake look as polished as any bakery masterpiece.
Step 5: Final Touches
Place the completed cakes into your bento containers using the parchment paper to keep everything neat. Use remaining buttercream to create colorful piped decorations, or get creative with gel frosting and sugar letters for personalized messages—your Bento Cake (Simple & Delicious!) Recipe is now ready to impress!

Make Ahead and Storage
Storing Leftovers
Store any leftover bento cakes in an airtight container in the refrigerator to keep the buttercream fresh and the cake moist. They’ll stay delicious for up to 3 days, so you can enjoy this treat over a few occasions.
Freezing
You can freeze assembled bento cakes by wrapping them tightly in plastic wrap and placing them in a freezer-safe container. Thaw overnight in the refrigerator before serving to preserve their delightful texture and flavor.
Reheating
Since this is a delicate cake with buttercream frosting, reheating isn’t recommended. Instead, serve chilled or at room temperature to maintain the perfect balance of moist cake and creamy frosting.
FAQs
Can I use homemade cake instead of a cake mix?
Absolutely! Using your favorite homemade cake recipe works wonderfully. Just ensure the cake is firm enough to cut into circles without crumbling.
What if I don’t have a half sheet pan?
You can use a jelly roll pan or any baking sheet with shallow sides. Just adjust your batter quantity to fill the pan evenly, and keep an eye on baking times.
Can I substitute the butter for margarine or oil?
For best flavor and texture, stick with unsalted butter. Margarine or oil will affect the frosting’s consistency and taste.
How long can I keep the frosting at room temperature?
Buttercream frosting can sit out for a couple of hours, but it’s best kept refrigerated if you plan to store the cake longer to avoid spoilage.
Is this recipe suitable for beginners?
Definitely! The Bento Cake (Simple & Delicious!) Recipe is designed to be approachable and forgiving, perfect for bakers of all levels who want to impress with a beautiful mini cake.

Ingredients
Cake
- 1 (15-22 ounces) box prepared cake mix of your choice
- 2 teaspoons simple syrup
Vanilla Buttercream Frosting
- 1 cup unsalted butter, room temperature (recommended Kerrygold)
- 1 teaspoon vanilla extract
- 2 2/3 cups powdered sugar
- 1/2 cup heavy whipping cream, room temperature
Optional Decorations
- Sprinkles
- Gel frosting
Instructions
- Preparing the Cake: Preheat your oven to 350°F (175°C). Prepare a 12×17 inch half sheet or jelly roll pan by spraying it with cooking spray and lining it with parchment paper, pressing the paper into the corners and up the sides.
- Spreading Batter: Pour the prepared cake mix batter into the pan and use a spatula to spread it evenly.
- Baking: Bake the cake for 20-24 minutes until the top is golden brown and a toothpick inserted into the center comes out clean. Remove from oven and let cool completely.
- Removing the Cake: Use a butter knife to loosen the edges of the cake from the pan. Cover the cake with parchment paper and a wire cooling rack, then carefully flip the pan to release the cake onto the rack.
- Making Buttercream Frosting: Beat the butter with a paddle attachment on medium speed for 30 seconds until smooth. Add vanilla extract and mix on low until combined.
- Incorporating Powdered Sugar and Cream: Gradually add powdered sugar 1/2 cup at a time, stopping after 1 1/2 cups to pour in the heavy cream. Finish adding powdered sugar and beat on low until fully incorporated and smooth.
- Cutting Cake Circles: Using a 6-inch circle biscuit cutter, cut out 12 circle layers from the cooled cake. Set aside on a wire rack and prepare four 9-inch squares of parchment paper for assembly surfaces.
- Assembling the Cakes: Place a 9-inch parchment square on your work surface. Spread a small amount of frosting to anchor the first cake circle, then drizzle 1 teaspoon of simple syrup on the cake.
- Layering and Frosting: Spread an even layer of vanilla buttercream frosting over the cake. Add the second cake circle, drizzle with another teaspoon of simple syrup, and continue layering.
- Applying Crumb Coat: After stacking, spread a thin layer of buttercream all over the cake as a crumb coat. Smooth with a spatula or cake scraper.
- Chilling the Cakes: Place the crumb-coated cakes in the freezer for 10 minutes until the frosting firms.
- Final Frosting Layer: Remove cakes from freezer and apply a thicker, smooth layer of buttercream frosting. Chill again in the freezer for 10 minutes.
- Transferring to Bento Containers: Carefully lift the cakes from the parchment paper and place them inside bento containers for storage or gifting.
- Decorating: Divide remaining buttercream into small portions and color as desired. Use piping bags with different tips to decorate the cakes or add gel frosting/sugar letters for messages.
Notes
- Ensure the cake is completely cooled before cutting or frosting to prevent crumbling.
- Simple syrup helps keep the cake moist and flavorful within the layers.
- You can customize the buttercream color and decorations to match any theme or occasion.
- Store assembled bento cakes in the refrigerator and serve at room temperature for best taste.
- If you prefer a dairy-free version, substitute butter and heavy cream with plant-based alternatives.
