Strawberry:
Omit the vanilla extract.
Increase powdered sugar to 2 ½ cups
Add ¾ cup freeze-dried strawberriesfinely processed into a powder
Mint:
Replace the vanilla extract with ½ teaspoon peppermint extract.
Optionally, add a drop or two of green food coloring for a minty visual touch.

Instructions
Prepare the Base: Melt butter in a 2-quart saucepan over medium-low heat. Stir continuously with a heat-resistant spatula as the butter hisses and pops. If brown bits appear, reduce the heat and stir until the butter becomes silent.
Cool and Strain: Pour the melted butter through a fine mesh strainer into the bowl of a stand mixer fitted with a paddle attachment.
Mix Ingredients: Add the vanilla extract and salt to the melted butter. Gradually add the powdered sugar and mix on low speed until combined. Increase to medium speed and beat for about 5 minutes until the mixture is creamy and smooth.
Transfer and Use: Spoon the filling into a pastry bag with a ½-inch plain tip and use immediately.
Notes
This filling cannot be prepared in advance; assemble immediately after making for best results.
Adjust the filling consistency by processing additional powdered sugar for a firmer texture if needed.
