Step 1: Make the Donuts

1. Preheat oven to 350°F (175°C) and grease a heart-shaped donut pan (or use a regular donut pan).
2. In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
3. In another bowl, whisk buttermilk, egg, melted butter, and vanilla extract until combined.
4. Add wet ingredients to the dry ingredients and mix until just combined (do not overmix).
5. Spoon or pipe the batter into the prepared donut pan, filling each about ¾ full.
6. Bake for 10-12 minutes, or until donuts are lightly golden and a toothpick comes out clean.
7. Let donuts cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Step 2: Make the Strawberry Cheesecake Filling

1. In a bowl, beat cream cheese, powdered sugar, and vanilla extract until smooth.
2. Fold in finely chopped strawberries and mix until combined.
3. Transfer to a piping bag fitted with a small tip.

Step 3: Fill the Donuts

1. Using a small knife or piping tip, gently poke a hole into the side of each donut.
2. Pipe strawberry cheesecake filling into each donut until slightly puffed.

Step 4: Make the Glaze & Decorate

1. In a bowl, whisk together powdered sugar, milk, and vanilla extract until smooth.
2. Add a drop of pink or red food coloring for a festive touch.
3. Dip each donut into the glaze, letting excess drip off.
4. Sprinkle with freeze-dried strawberries or heart sprinkles before the glaze sets.
