Preheat your oven to 350 degrees Fahrenheit and fill a muffin tin with liners. 

In a large mixing bowl, cream the butter and sugar together until homogenous and smooth.

Beat in the eggs and vanilla extract until the eggs are fully incorporated into the batter.

Gently beat in the baking powder and flour until no clumps of dry ingredients remain in the mixture. If the mixture is a little crumbly, that is okay.

Add the milk and strawberries and whisk again until the strawberries are evenly distributed throughout the batter.

Divide the batter among 12 muffin liners and bake for 20 minutes.

Serve the muffins hot or allow them to cool for 15-20 minutes before serving.
