In a medium saucepan, stir together the strawberries, sugar, and lemon juice. Bring to a simmer over medium heat. Cook, stirring occasionally, until thickened, about 5-7 minutes. Remove from heat and let cool slightly.
In a medium bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. In a small bowl, whisk together the half and half and white vinegar. Let sit five minutes.
Combine the half & half, egg, oil, and vanilla, and mix until combined. Pour the wet ingredients into the dry ingredients, and mix until just combined (a few small lumps are okay). Pour ¼ cup of the strawberry sauce into the batter and mix gently.
Preheat a griddle or large skillet over medium heat. Spray with cooking spray and then Pour the batter by ¼ cup scoops onto the preheated skillet. Cook 3-4 minutes, or until there are bubbles throughout the batter and the edges look dry, then flip and cook an additional 1-2 minutes.
Serve warm with strawberry sauce and whipped cream.
