Activate Yeast
In a small bowl, mix warm water, 1 tbsp sugar, and dry yeast. Let sit for 10 minutes until frothy.

Make Dough
In a mixing bowl, combine flour, sugar, egg yolks, milk, and softened butter. Add activated yeast and knead for 15–20 minutes until smooth.

First Proof
Transfer the dough to a greased bowl, cover, and let rise in a warm place for 1.5 hours or until doubled in size.

Shape Donuts
Roll the dough to 0.1-inch (0.25 cm) thickness. Cut into 2.5-inch rounds using a cookie cutter. Place on parchment paper squares.

Second Proof
Let the cut dough rest and rise for 30 minutes until puffy.

Fry the Donuts
Heat oil to 175°C (347°F). Fry 2–3 donuts at a time for 2 minutes per side until golden. Drain on paper towels.

Prepare Cheesecake Filling
Mix softened cream cheese and powdered sugar until smooth. Add strawberry jam and stir until creamy.

Fill Donuts
Use a piping bag to inject filling into each donut through the side or top.

Decorate
Top with a dollop of jam, a fresh strawberry, and a dusting of powdered sugar
