A compilation of ingredients for making 3 delicious and easy-to-make avocado ice cream recipes.

1. Basic Buttercream

Mildly sweet, soft and smooth, easily pairs with many types of cakes.

  • 375g powdered sugar

  • 225g unsalted butter

  • 1 teaspoon vanilla extract (optional)

  • 1–2 tablespoons of fresh cream, milk, or a mixture of half each.

  • A pinch of salt (optional)

2. Chocolate Buttercream

Rich in chocolate flavor, creamy, perfect for cakes and cupcakes.

  • 450g unsalted butter

  • 350g medium-sweet chocolate (melted and cooled)

  • 3 tablespoons of milk

  • 1 1/2 tablespoons vanilla extract

  • 625g powdered sugar

3. Swiss Meringue Buttercream

Smooth, light, not too sweet, easy to pipe beautifully.

  • ½ cup egg whites (about 4 large eggs)

  • 280g fine granulated sugar

  • 1 tablespoon vanilla extract

  • 225g unsalted butter

  • A pinch of salt (optional)

Method 1: Making smooth and beautiful basic buttercream frosting – The secret to perfect cakes.

Step 1: Cut the butter into small pieces before mashing.

  • Cut the butter into small pieces and put them in a bowl.

  • This helps the butter soften faster and makes it easier to whip, creating a smooth and even texture for the buttercream.

Step 1: Cut the butter into small pieces before mashing.

Step 2: Beat the butter properly to make the cream smooth and fluffy.

  • Use an electric mixer (handheld or stand mixer) with a whisk attachment.
  • Beat the butter on low speed for about 5 minutes.

When butter is whipped properly:

  • The color has faded to a lighter shade (almost white).

  • The volume has doubled.

  • Soft, smooth, and lightweight texture.

Step 2: Beat the butter properly to make the cream smooth and fluffy.

Step 3: Add sugar gradually to avoid splashing and to ensure the cream is smooth and even.

  • Add half of the powdered sugar to the bowl of whipped butter.

  • Mix well at low speed until the sugar is incorporated.

  • Don't add all the sugar at once – adding it little by little helps prevent splattering and results in a smoother mixture.

  • After the first portion has dissolved, continue adding the remaining sugar.

Step 3: Add sugar gradually to avoid splashing and to ensure the cream is smooth and even.

Step 4: Finish off the buttercream with the remaining ingredients.

  • In a bowl, combine the remaining sugar, vanilla extract (or other flavoring), milk or fresh cream, and salt (if using).

  • Beat at low speed until the mixture is completely combined.

Adjust the consistency of the buttercream according to your needs:

  • 1 tablespoon of milk/fresh cream → thicker cream, suitable for frosting cakes.

  • 2 tablespoons of milk/fresh cream → smoother cream, ideal for spreading or filling on cakes.

  • Not sure? Start with ½ teaspoon, then gradually add more until you reach your desired consistency.

Additional tip:

  • Use milk instead of fresh cream to make a lighter buttercream.

  • Add a pinch of salt to balance the sweetness if you don't like it too sweet.

Step 4: Finish off the buttercream with the remaining ingredients.

Step 5: Customize the color of the buttercream.

  • You can keep the cream's natural white color or add a few drops of food coloring to create vibrant colors.

  • Add the color gradually, stirring well after each addition to control the intensity.

Note:

  • Some flavoring ingredients, such as cocoa powder and chocolate, can be used to make pre-colored ice cream.

  • In these cases, the dye may not show up as the exact color, so test it on a small area first if you want to achieve a specific color.

Step 5: Customize the color of the buttercream.

Step 6: Whip thoroughly and adjust the consistency of the buttercream.

  • Add the remaining sugar to the mixture.

  • Increase the whisking speed to high and whisk for 2–3 minutes until the cream becomes light, fluffy, and smooth.

Adjust the structure:

  • If the cream is too thick:
    → Add 1 tablespoon of milk, fresh cream, or mix half of each.
    → Mix well, then add gradually if needed.

  • If the cream is too runny:
    → Add a little powdered sugar and mix until the desired consistency is achieved.

Step 6: Whip the buttercream until fully fluffy and adjust the consistency as needed.

Step 7: Proper storage and use of buttercream

  • Ready to use: Use for brushing or piping flowers to decorate cakes.

Preserve:

  • Place the buttercream in a zip-lock bag or airtight container.

  • It can be stored in the refrigerator for up to 2 weeks.

  • Before reusing, allow the cream to reach room temperature and gently whip it again until smooth.

With the cake already covered with buttercream:

  • It should be consumed within 3 days to maintain the best flavor and texture.

Method 2: Tips for making chocolate buttercream at home – A simple yet delicious recipe.

Step 1: Prepare the steamer properly.

  • Pour water into the pot, then place a heat-resistant bowl on top of the pot.

Step 2: Melt the chocolate evenly and smoothly.

Step 3: Notes on using melted chocolate

Step 4: Beat the butter until smooth and fluffy.

  • You can use either a handheld or stand mixer.

Step 3: Dissolve the sugar in the egg whites.

Step 4: Steam the egg whites until they reach a safe temperature.

  • Heat the egg white and sugar mixture in a double boiler, stirring gently.

    • The egg whites begin to form stiff peaks when you lift the whisk (soft peak or firm peak, depending on your purpose).

    • The texture becomes more porous, smooth, and firm.

Step 5: Beat the egg whites after steaming.

Step 6: Finish off the egg white buttercream with vanilla and butter.

  • Reduce the mixer speed to medium-low.
