Expert Baking Tips
Cream the Butter
You could technically put all the ingredients in the bowl together and beat them at the same time.
However, this can leave chunks of butter/vegan baking stick throughout the frosting.
Your best bet is to beat the room temperature butter first until it is smooth and creamy for about two minutes.
Then beat in all the other ingredients.
Be Careful Not to Melt the Butter
If your butter/vegan baking stick is not at room temperature and soft, be careful if you plan on popping it in the microwave. Especially if you're using vegan baking sticks.
Vegan baking sticks are different than butter in the sense that if they are too melted in your frosting, they will create a liquid mess and your frosting will be sliding all over your cakes and cupcakes.
At that point, even putting the frosting in the fridge would not help. It will still be a liquid mess.
If you are using butter, popping the frosting in the fridge will sometimes help resolidify and make the frosting thicker and firmer but not always.
Step by Step Instructions
Here are the steps to make this frosting!
Step 1: Cream the Vegan Baking Stick or Butter
In the large bowl of an electric mixer or using a hand held mixer, beat the room temperature butter or vegan baking stick or butter until smooth and creamy. About 2 minutes.
Step 2: Add in the Vanilla and Lemon Zest
Add in the vanilla and lemon zest. Beat until combined.
Step 3: Add in the Remaining Ingredients Half at a Time
With the mixer on low speed, slowly add in half the confectioners’ sugar, half the lemon juice and half the water. Beat until combined. It will look chunky at first.
Step 4: Add the Second Half of Ingredients
Then add in the second half of the confectioners' sugar, lemon juice and water and beat until combined again, creamy and smooth.
How to Make this Vegan
Follow these simple steps to make sure the frosting is vegan:
- Make sure to use vegan baking sticks instead of butter.
- Only use pure vanilla extract that's made in a gluten free and vegan facility.
Recipe FAQs
If the frosting is too thick, add more water ¼ teaspoon at a time until you get the desired consistency.
If the frosting is too thin, add more confectioners’ sugar, 1 tablespoon at a time until you get the desired consistency.
You can make this frosting the night before you need to use it.
Store it in an airtight container or a bowl covered with plastic wrap, in the fridge.
When ready to use, let it come to room temperature and rewhip to get that creamy consistency.
This recipe makes about 5 cups of frosting.
That should be enough for a 3-4 layer cake or 24 cupcakes.
For 12 cupcakes or a one layer cake, divide the recipe in half.
No you don't, however the frosting will have a much more mild lemon flavor without it.
