Start by beating the butter in the bowl of a stand mixer with a paddle attachment. You can also do this in a large bowl using a handheld mixer. You will need to beat the butter for at least 3-4 minutes or until it gets creamy.
Once the butter is creamy, add the confectioner’s sugar. Beat the butter and sugar on low settings for a minute. Now add milk, almond, vanilla extract, and salt. Beat the mixture on high settings until it gets smooth and creamy. It may take 3-4minutes.
Cover the bowl with a wrapping sheet and place the mixture in the refrigerator. You must chill it for a minimum of 2 hours to get it solid and manageable.
Line a baking sheet with parchment paper and remove the chilled and frozen buttercream from the refrigerator.
Scoop out the buttercream using a one tablespoon scoop and give it a ball shape. Place the scoop on the parchment-lined baking sheet. If you feel like the buttercream is getting too sticky, rub your fingers with the confectioner’s sugar.
Place the scoops in the refrigerator to chill. One to two hours of refrigeration time is advisable. However, you can store up to 24 hours.
If you have some leftover frostings, you can skip this step.
