1-First Step: Activate the Yeast Begin by dissolving 2 ¼ teaspoons of active dry yeast (7 g) in ¾ cup of lukewarm milk (200 ml). Let it sit for about 5 minutes until it becomes foamy, which ensures the batter will rise properly and give those airy pockets.

2-Second Step: Mix the Dry Ingredients In a large bowl, combine 2 cups of all-purpose flour (250 g), 2 teaspoons of granulated sugar (10 g), and 1 teaspoon of salt (5 g). Make a well in the center of this mixture to prepare for adding the wet ingredients, which helps blend everything evenly without overmixing.

3-Third Step: Combine Wet and Dry Ingredients Pour the foamy yeast mixture into the well, then add 1 egg, 1 teaspoon of vanilla extract, and 1 tablespoon of melted butter. Mix everything together until the batter is smooth and slightly sticky, taking care not to overwork it for the best texture; this step should take about 2-3 minutes.

4-Fourth Step: Let the Batter Rest Cover the bowl and let the batter rest for 45 minutes in a warm place. This rising time is crucial as it allows the yeast to work its magic, creating those soft, airy interiors that define Belgian Croustillons.

5-Fifth Step: Heat the Oil Heat vegetable oil in a deep fryer or heavy pot to 180°C (350°F). Use a thermometer to maintain this temperature, as it’s key for achieving even frying and preventing the fritters from absorbing too much oil.

6-Sixth Step: Fry the Fritters Using a spoon or ice cream scoop, drop small portions of the batter into the hot oil, frying in batches to avoid overcrowding. Each batch should cook for 3 to 4 minutes, turning occasionally until they turn golden brown and puff up nicely; this ensures a crisp exterior while keeping the inside tender.

7-Seventh Step: Drain and Dust Remove the fritters with a slotted spoon and drain them briefly on paper towels to remove excess oil. While they’re still warm, dust them generously with powdered sugar for that classic finish, enhancing their sweet appeal.

8-Final Step: Serve Immediately Serve your Belgian Croustillons right away with optional accompaniments like melted chocolate, fruit preserves, or honey. For a fun twist, consider variations such as adding apples or raisins to the batter.
