Ingredients
  

The Dough
  • 72 g all-purpose flour
  • 84 g protein powder Whey/Casein blend recommended
  • 20 g cold unsalted butter cut into small pieces
  • 90 g nonfat Greek yogurt
  • 20 g zero-calorie sweetener granulated
  • 0.5 tsp baking powder

Method
 

  1. In a medium bowl, whisk together the flour, protein powder, sweetener, baking powder, and salt.
  2. Add the cold butter and work it into the dry ingredients with your fingers or a fork until the mixture looks sandy.
  3. Mix in the Greek yogurt and vanilla extract. Add the cold water and stir until a soft dough forms.
  4. Cover the dough and let it rest for 15 minutes to allow the flour and protein to hydrate.
  5. Roll the dough between two sheets of parchment paper into a rectangle. Cut into 8 rectangles.
  6. Place 15g of jam on 4 of the rectangles. Top with the remaining rectangles and crimp edges with a fork. Poke vent holes in the top.

Notes

High Protein Toaster Strudel Tips & Expert Strategy

WHEY VS CASEIN: This recipe requires a whey/casein blend. Using 100% whey can result in a rubbery texture that is difficult to roll and chew.
TEXTURE EXPECTATION: These are softer and breadier than a traditional flaky pie crust. They are meant to be moist and satisfyingly dense to hold the high protein content.
PATCHABLE DOUGH: Because of the yogurt, this dough is forgiving. If it cracks while rolling, pinch it back together with your fingers.
THE MELLOW EFFECT: These pastries taste better after resting for 5 minutes after air frying. The steam settles and the crust develops a better bite.
