Preheat oven to 375 F. Line a muffin tin with muffin liners and set aside.
In a small bowl, combine the flour, baking powder and salt. Stir and set aside.
In a large bowl, mix the butter, eggs, buttermilk, sugar, and lemon juice until light and frothy. Add the dry ingredients and stir until just moistened.
Add in the strawberries and stir until mixed throughout.
Scoop 1/4 cup of batter into each muffin liner.
Bake for 15-18 minutes, until slightly golden and an toothpick inserted in center comes out clean.
