Line two baking sheets with parchment paper. Set aside.
In a medium bowl sift together almond flour and confectioners sugar. Set aside.
Beat egg whites in the bowl of a standing mixer using a whisk attachment until soft peaks form. (about 3 minutes) Slowly add granulated sugar and vanilla and continue to beat on high for 2 minutes until stiff peaks form. Add almond flour mixture to egg whites and fold in slowly by hand until well incorporated.
Scoop macaron mixture into a pastry bag fitted with a #806 tip. Pipe quarter size circles (1 - 1 1/2 inch) on parchment lined baking sheets about 1 inch apart. After piping leave out to rest on your counter at room temperature for 2 hours.
Preheat oven to 300 degrees. Bake macarons for 15-17 minutes. I only baked one tray at a time. Cool on tray before frosting.
Buttercream Frosting: In the bowl of a standing mixer fitted with a paddle attachment beat butter and vanilla extract on medium speed until light and fluffy. (about 2 minutes) Turn mixer to low and slowly add confectioners sugar. Beat for 2 minutes scraping down the bowl after 1 minute. Add the milk one teaspoon at a time until the frosting is at a good piping consistency and continue to beat for 3-4 minutes. Scoop the buttercream frosting into a pastry bag fitted with the #806 tip and pipe the buttercream onto the flat side of one of the macarons, top with 4 to 5 finely chopped pieces of strawberry and then sandwich together.
