01 - Combine strawberries, sugar, and lemon juice in a small saucepan. Cook over medium heat for 5–7 minutes, stirring occasionally, until strawberries release their juices and the 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 until well combined.
04 - Whisk buttermilk, eggs, melted butter, and vanilla extract in a separate bowl until blended.
05 - Pour wet ingredients into dry ingredients and gently fold until just combined. Do not overmix; small lumps are acceptable for fluffy pancakes.
06 - Preheat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil.
07 - Pour approximately 1/4 cup of batter per pancake onto the skillet. Add a heaping teaspoon of cheesecake mixture to the surface and swirl gently with a knife tip or skewer. Cook for 2–3 minutes until bubbles form and edges appear set. Flip and cook for an additional 1–2 minutes until golden brown and cooked through.
08 - Repeat with remaining batter and cheesecake swirl, greasing the skillet as needed. Serve warm with strawberry sauce and additional fresh strawberries if desired.
