Place milk, flour, egg whites, applesauce, vanilla extract, sucralose sweetener, and salt in a bowl. Whisk batter thoroughly.
Heat a large skillet over medium heat. Spray with cooking spray. Pour half of batter into the center of the skillet; turn skillet several times to spread evenly. Cook until golden brown, about 2 minutes. Flip carefully; add 1/2 the blueberries to the center of the crepe. Cook until bottom is golden brown, about 2 minutes more.
Spoon 1/4 of the yogurt over the berries. Fold sides of crepe over the center; remove from skillet. Sprinkle lightly with 1/2 the sugar. Spoon another 1/4 of the yogurt on top; sprinkle with 1/2 the almonds. Repeat to make the second crepe.
