In a medium bowl, whisk together egg yolks, sugar, and cornstarch until smooth. Gradually pour hot milk over egg mixture while whisking continuously to temper the eggs.
03 -
Strain mixture back into saucepot. Cook over medium heat, whisking constantly, until mixture boils and thickens to a soft pudding consistency, approximately 5-10 minutes.
04 -
Remove from heat and whisk in butter and vanilla. Transfer to a heat-safe bowl and cover with plastic wrap directly touching the surface to prevent skin formation.
05 -
Refrigerate pastry cream for 1-2 hours until cold and set.
06 -
Warm milk to approximately 43°C. In a large bowl, whisk together milk, 1 tablespoon sugar, and yeast. Let stand 5-10 minutes until surface becomes foamy, indicating active yeast.
07 -
Add remaining sugar, egg, vanilla, and melted butter to the yeast mixture. Whisk until combined.
08 -
Add half the flour to wet ingredients and mix with a spatula or wooden spoon until a rough, sticky mixture forms. Add remaining flour and salt, then mix until it forms a cohesive dough ball.
09 -
Turn dough onto a floured surface and knead for 5-10 minutes, adding flour as needed to prevent sticking, until smooth and elastic.
10 -
Oil a large bowl and place dough inside, turning to coat all surfaces. Cover and let rise in a warm place for 45-60 minutes until doubled in size.
11 -
Line two large baking sheets with parchment paper.
12 -
Punch down risen dough and turn onto a lightly floured surface. Roll dough to approximately 1.3cm thickness. Use a 7.5cm round cookie cutter to cut donut shapes.
13 -
Place cut donuts on parchment-lined baking sheets, leaving at least 7.5cm between each. Gather and reroll scraps to cut remaining donuts. Cover and let rise in a warm place for 30-45 minutes until doubled.
14 -
Preheat oven to 190°C. Bake donuts in center rack for 10-12 minutes until puffed and golden brown on top. Avoid overbaking to prevent dryness.
15 -
Immediately transfer baked donuts to a wire rack and cool completely before filling.
16 -
Create a hole in the side of each donut using a sharp paring knife. Fill a piping bag with chilled pastry cream, cut tip off, and pipe filling into each donut until cream begins to push out of the hole.
17 -
Place filled donuts in refrigerator until ready to apply sugar topping.
18 -
In a medium skillet, combine sugar, water, and salt. Heat over medium-high until boiling, swirling pan gently to ensure even melting. Do not stir to prevent crystallization.
19 -
Continue boiling until sugar begins to brown to a honey color. Remove from heat and allow residual heat to continue browning to amber color, approximately 1 minute.
20 -
Using long-handled tongs, dip tops of donuts into caramelized sugar. If sugar hardens during process, warm over low heat to liquify again.
21 -
Place topped donuts on wire rack or parchment paper to set for 5-10 minutes until sugar hardens. Serve immediately for optimal texture and flavor.
