What is a Bento Cake?

Originating from the Japanese culture of carefully arranged, single-portion meals, the bento cake adapts this concept into the dessert world. Traditionally, a bento is a packed lunch, often featuring a variety of foods artfully arranged in a box. It’s all about balance and presentation.

This idea has evolved into these petite cakes, offering a sweet, personal-sized treat that’s as pleasing to the eye as it is to the palate. They’re small, simple, and meant to bring joy in a single serving.

Why You’ll Love This Small Bento Cake

  • Perfect for one: No need to worry about a whole cake tempting you for days.
  • Minimal ingredients: You probably already have most of what you need in your pantry.
  • Quick to bake: In just 25 minutes, you’ll have a delightful little cake ready to decorate.
  • Impressive-looking: These cakes look like they came from a fancy bakery, but you made it yourself!

Essential Equipment for Your Small Bento Cake

  • 5-inch cake tins: These are the perfect size for a bento cake. I recommend these non-stick ones from Amazon; they make releasing the cake a breeze!
  • Hand mixer: A hand mixer makes creaming butter and sugar together so much easier. This one from KitchenAid is my go-to, it’s powerful and reliable.
  • Cooling rack: A must for cooling your cakes evenly. This one from Wilton is sturdy and affordable.
  • Small offset spatula: Ideal for smoothing frosting on those tiny cakes. This Ateco spatula gives you the precision you need.
  • Piping bags and tips: For adding those cute decorations! I love this set from Wilton because it comes with various tips for different designs.
  • Bento box: Of course, you need a bento box to present your cake! This cute one from Bento&Co is perfect for gifting your little masterpiece.

Small Bento Cake Ingredients

  • 100 g flora buttery/margarine (take out of the fridge for around an hour before using)
  • 100 g caster sugar
  • 1/2 tsp vanilla extract
  • 2 large eggs
  • 100 g self raising flour

Step-by-Step Baking Instructions

  1. Preheat your oven to 160 for a fan oven, 180 for a non-fan oven, or gas mark 4.
  2. Line two 5″ cake tins. I like to grease my tin with butter and sprinkle with flour, but you can also use greaseproof paper.
  3. Put your butter and sugar in a bowl and cream well with a hand mixer. This should turn lighter in color.
  4. Gradually add the eggs and the vanilla extract into the mix. If the mix curdles, then add a little flour, but this usually isn’t necessary.
  5. Once you have added all the eggs, mix in the flour by folding it into the mix. Make sure you scrape down all the sides to get all the mix combined.
  6. Pour the cake mix into the tins. For an even bake, split the batter into the tins by using a weighing scale to ensure there are equal amounts in each tin.
  7. Make a dip in the center of the mix so the cake doesn’t bake too humped.
  8. Bake this for 25 mins. A skewer should come out clear once the cake is fully baked.
  9. Leave the cake to cool for around 10 mins before popping out of the tin onto a cooling rack.
  10. Leave the cake to cool completely; wrap in cling film until you are ready to level and fill. Uncooked flour can contain germs, so avoid tasting the batter before it’s baked.

Alternative Frosting Options

While buttercream is a classic choice, there are so many other delicious frostings to try! Cream cheese frosting adds a tangy twist, and it’s super easy to make.

Just beat together cream cheese, butter, powdered sugar, and a splash of vanilla extract until smooth and creamy.

Simply heat heavy cream and pour it over chocolate chips, then stir until melted and smooth. You can also find tons of recipes online for frostings like Swiss meringue buttercream or stabilized whipped cream.

Decorating Techniques for Small Bento Cakes

Decorating these tiny cakes is where the real fun begins! For rosettes, use a star tip and pipe swirls starting from the center and working your way out. Shells are easy to create with a shell tip; just squeeze and release pressure as you pull away.

Writing messages or names can be done with a small round tip. Don’t be afraid to experiment with different colors, sprinkles, and edible glitter to make your bento cake truly unique! If you’re looking for more baking ideas, check out our category on treats and drinks.

How to Scale This Recipe

If you want to make a slightly larger bento cake, say a 4-inch cake instead of a 5-inch one, you’ll need to adjust the recipe accordingly.

The easiest way to do this is to calculate the ratio of the new size to the original size and then multiply all the ingredients by that ratio. For example, if you are adjusting from a 5-inch cake tin to a 4-inch cake tin the ratio is (4/5=0.8).

Therefore, you should multiply all of your ingredients by 0.8 to adjust the recipe.

Troubleshooting Common Problems

  • Dry cake:** This can happen if you overbake the cake or use too much flour. Make sure to measure your ingredients accurately, and don’t bake the cake for longer than necessary.
  • Cracked frosting:** This often occurs if the frosting is too thick or the cake is not completely cooled before frosting. Try adding a little milk or cream to your frosting to thin it out, and always let your cake cool completely before frosting.
  • Uneven layers:** To avoid uneven layers, make sure to distribute the batter evenly between the cake tins. Using a weighing scale helps.

Packaging & Presentation Ideas

Presentation is key when it comes to bento cakes! You can find adorable bento boxes online or at your local kitchen supply store.

Add a ribbon or a personalized sticker for an extra touch. For a DIY option, use a small cardboard box and decorate it with colorful paper and markers. Don’t forget a cute little spoon or fork!

Storage and Shelf Life

Bento cakes can be stored at room temperature for up to 2 days or in the refrigerator for up to a week. Wrap them tightly in cling film to prevent them from drying out. Proper storage can prevent foodborne illness.

Business Perspective: Selling Bento Cakes from Home

If you’re looking to turn your bento cake hobby into a business, there are a few things to consider. First, research your local food safety regulations.

You’ll also need to determine your pricing strategy, taking into account the cost of ingredients, your time, and any packaging expenses. Marketing your cakes through social media or local events is a great way to attract customers.
