01 - Combine strawberries, sugar, and lemon juice in a small saucepan. Cook over medium heat for 5-7 minutes, stirring occasionally, until strawberries release juices and mixture thickens slightly. Remove from heat and set aside.
02 - Beat softened cream cheese, sugar, egg yolk, and vanilla extract in a small bowl until smooth and creamy. Set aside.
03 - Whisk together flour, sugar, baking powder, baking soda, and salt in a large bowl.
04 - Whisk buttermilk, eggs, melted butter, and vanilla in a separate bowl. Pour wet ingredients into dry ingredients and stir gently until just combined. A few lumps are acceptable.
05 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil.
06 - Pour approximately 1/4 cup batter onto the skillet for each pancake. Place a heaping teaspoon of cheesecake mixture on the surface and swirl gently with a knife tip or skewer.
07 - Cook for 2-3 minutes until bubbles form on surface and edges appear set. Flip and cook an additional 1-2 minutes until golden brown and cooked through.
08 - Continue with remaining batter and cheesecake swirl, greasing the skillet as needed. Serve warm topped with strawberry sauce and additional fresh strawberries if desired.
