If you're already a fan of my Condensed Milk Buttercream recipes, this one is a must-try. The melted Aero gives a cool minty twist that pairs beautifully with chocolate cupcakes.

What Is Aero Condensed Milk Buttercream?

Aero Condensed Milk Buttercream is a whipped frosting made with melted Aero bars, unsalted butter, and sweetened condensed milk. What makes it stand out is the texture: ultra-smooth, pipeable, and completely free from icing sugar.

Instead of using powdered sugar for structure, this buttercream gets its body from whipping butter and condensed milk until fluffy, then folding in cooled melted Aero. The result is a glossy, chocolate mint frosting that holds its shape beautifully.

You can adjust the flavor by using different Aero varieties: mint, milk chocolate, or even caramel if it becomes available locally.

Why You’ll Love This Aero Buttercream

This isn't your average mint buttercream. By melting Aero bars into the base, you get a smooth texture with real chocolate flavor, not just mint extract. Plus, the condensed milk takes the place of icing sugar, giving you a naturally glossy finish with less sweetness.

You can easily scale this recipe for bigger batches or adjust the color with just a drop of green food dye to match the minty vibe.

Ingredient Notes

Aero Mint Condensed Milk Buttercream Ingredients Cupcake Savvy

Aero Chocolate. Use double the quantity in the recipe card for a richer mint-chocolate taste. Mint Aero works best, but milk chocolate Aero is also great. Chop it finely so it melts quickly and smoothly. Let it cool to lukewarm before mixing to avoid melting the butter.
Unsalted Butter. This is the base of the buttercream. It gives body, structure, and richness. Soften to room temp before whipping. Whip it well first for a light, fluffy texture that pipes beautifully.
Sweetened Condensed Milk. No icing sugar needed! Condensed milk adds sweetness and creates a smooth, stable texture. Use full-fat for the best result. Don't substitute with evaporated milk, it won't work.
Green Food Coloring (optional). A drop or two gives a subtle minty hue. Not essential, but adds a nice touch. Gel or concentrated colors work best, use a light hand.
Optional Toppings. Add a chocolate drizzle or chopped Aero on top for flavor and texture. Try melted chocolate, ganache, or chocolate sauce. Sprinkle with extra Aero chunks to finish.

How to Make Aero Buttercream

Melt the Aero: Chop and melt the chocolate on 50% power in the microwave. Stir every 30 seconds until smooth. Let it cool to lukewarm.

Whip the butter: Beat softened butter for 1-5 minutes until light and fluffy. The longer you beat, the smoother it gets.

Next add the condensed milk: Pour in the condensed milk and beat until fully combined and silky.

Add melted Aero: Mix in the cooled melted chocolate until fully incorporated.

Add colour (optional): A drop or two of green food colour brings out the mint vibe. Mix briefly to blend.

Remove air bubbles: Switch your mixer to the lowest speed for 2-3 minutes. Or use a silicone spatula to press and fold the Areo buttercream for a smooth finish.

Tips for Smooth, Pipeable Condensed Milk Buttercream

Always beat the butter well before adding anything else
Let your melted Aero cool slightly so it doesn't melt the butter
Mix low and slow at the end to eliminate air bubbles
Use a 1M piping tip for tall, soft-serve style swirls

How Much Buttercream This Recipe Makes

This recipe yields about 4½ to 5 cups of Aero buttercream, which is enough to:

Pipe 12 tall cupcake swirls
Frost 24-26 regular cupcakes
Cover a two-layer 8-inch cake

How to Remove Air Bubbles from Buttercream

Air bubbles can mess with your piping and make your Areo Buttercream look rough instead of smooth. The good news? You can fix it.

After mixing, turn your mixer to the lowest speed and let it run for 2-3 minutes. This slows everything down and helps knock out most of the trapped air.

You can also use a silicone spatula to press and fold the buttercream against the sides of the bowl. This method smooths it out and gives a super silky finish, perfect for tall cupcake swirls or clean cake edges.

Avoid over-whipping once everything is combined, that's what causes most of the bubbles in the first place.

FAQs - Aero Condensed Milk Buttercream

Can I use regular Aero instead of mint Aero?

Yes! You can use milk chocolate Aero if you prefer a plain chocolate flavor instead of mint. The method stays the same.

Can I make this buttercream ahead of time?

Absolutely. Store it in the fridge for up to 1 week or freeze for up to 2 months. Re-whip after bringing to room temperature.

Does condensed milk buttercream crust like American buttercream?

No, this style stays soft and smooth. It doesn't form a crust, which makes it ideal for silky finishes and swirls.

Is condensed milk the same as evaporated milk?

No, condensed milk is sweetened and thicker. Evaporated milk won't work for this recipe, so make sure to use the right one.
