Preheat the oven to 350℉.
Line a baking sheet with parchment paper or a silicone mat.
Using an electric mixer, cream together the butter and sugar until light and fluffy. This may take 3-4 minutes.
Stir in the lemon juice, vanilla extract, egg (if using) and food dye (if using). Stir until combined.
Next, stir in the flour and baking powder until a dough forms. Do not overmix.
Fold in the diced strawberries and half a cup of the white chocolate chips.
Using your hands, as the dough can be very thick and dry, work the dough together, almost as you would knead bread dough.
Scoop the cookie dough, approximately two tablespoons at a time, and work the dough into a compact ball, then place on the cookie sheet. Repeat with remaining dough. This dough is dry and crumbly, you want to use some elbow grease to work the dough balls together.
Bake for 12-14 minutes or until the bottom of the cookies are slightly golden.
Remove from oven and place baking sheet onto a wire cooling rack.
Add a few more white chocolate chips on top of each cookie as soon as they are removed from the oven.
Allow to cool for at least ten minutes prior to removing from the pan with a spatula.
