Here are some quick visual instructions. Don't forget that full recipe instructions with exact ingredients can be found in the recipe card below!
- Place fresh or frozen strawberries in a saucepan with lemon juice and cook over medium heat for about 5 - 7 minutes until you get a thick strawberry compote.
- Mash the strawberries with a potato masher or a fork and continue cooking if it still seems too liquid.
- Blend the mixture in a blender or with an immersion blender, then strain it through a fine sieve to remove the seeds.


- Place the egg whites and sugar in the bowl of your stand mixer or in a heatproof container.
- Cook the egg white mixture in a double boiler over a medium saucepan containing a little simmering water heated on medium heat.
- While continuously stirring with a hand whisk, monitor the temperature until it reaches 131°F/55°C and until the sugar is completely dissolved.


- Transfer the mixture into the bowl of your stand mixer fitted with the whisk attachment and beat on high speed for about 10 minutes until you achieve a stiff meringue.
- Reduce the mixer speed and gradually add the softened butter pieces into the meringue mixture, then increase the speed to high until you obtain a smooth buttercream.


- Add the strawberry puree, vanilla extract, and a little red food coloring, then beat again for 2 minutes until you get a smooth and pink buttercream.
- Replace the whisk attachment with the paddle attachment and mix at slow speed to soften the cream and reduce air bubbles.

Best Tips For Strawberry Buttercream Frosting

Variations & Substitutions
Recipe questions
Can I use frozen strawberries instead of fresh ones for the puree?
Yes, you can use frozen strawberries. No need to thaw them before cook them to make the puree.
How do I fix grainy buttercream?
If the buttercream becomes grainy, it's likely because the butter was too cold when added. To fix it, let the buttercream come to room temperature and re-whip until smooth.
Can I use salted butter instead of unsalted butter?
It's best to use unsalted butter to control the saltiness of the buttercream. However, if you only have salted butter, you can use it, but reduce or omit any additional salt in the recipe.
My buttercream is too runny. What should I do?
If the buttercream is too runny, it may be because the butter was too soft or the meringue was too warm when adding the butter and getting that soupy frosting. Place the bowl in the refrigerator for 15-20 minutes to firm up slightly, then re-whip until the desired consistency is reached.
Can I use this buttercream for piping decorations?
Yes, this buttercream is suitable for piping decorations. Just make sure it's at the right consistency for piping - firm enough to hold its shape but still soft enough to pipe smoothly. Adjust by adding more powdered sugar if needed.
Why does my strawberry buttercream look curdled?
Your strawberry buttercream may appear curdled due to excessive amounts of strawberry puree, which can compromise the texture of Swiss meringue buttercream. Be mindful of the quantity used for a smoother consistency.
