Prepare the Donut Dough

• In a large bowl, combine the warm milk and active dry yeast. Let it sit for 5 minutes until frothy.
• Stir in the granulated sugar, egg, melted butter, and salt. Mix until combined.
• Gradually add the all-purpose flour, mixing until a soft dough forms. If the dough feels sticky, sprinkle in a little more flour.

Knead and Let Rise

• Transfer the dough to a floured surface and knead for 5-7 minutes until it’s smooth and elastic.
• Place the dough in a greased bowl, cover with a damp cloth, and let it rise in a warm place for 1 hour, or until it doubles in size.

Shape the Donuts

• After the dough has risen, gently punch it down to release air.
• Roll out the dough to about ½ inch thick on a floured surface.
• Use a 3-inch round cutter to cut out donut shapes. Place them on a parchment-lined baking sheet, cover with a damp cloth, and let them rise for another 30 minutes.

Fry the Donuts

• Heat vegetable oil in a deep fryer or pot to 350°F (175°C).
• Fry a few donuts at a time, cooking each side for 1-2 minutes until golden brown.
• Remove with a slotted spoon and drain on a paper towel-lined plate.

Make the Strawberry Cream Filling

• In a medium bowl, whip the heavy cream with an electric mixer until stiff peaks form.
• Gently fold in the strawberry jam and vanilla extract until well combined.

Fill the Donuts

• Once the donuts are cool enough to handle, use a piping nozzle or small knife to create a hole in the side of each donut.
• Spoon the strawberry cream into a piping bag fitted with a round tip. Pipe the filling generously into each donut.

Serve and Enjoy

• Dust the donuts with powdered sugar for an extra touch of sweetness, if desired.
• Serve fresh and enjoy the perfect combination of fluffy donuts and creamy strawberry filling.
