Method
- Grate cold (fridge-temperature) butter on a box grater onto a plate and freeze it before starting anything else. Room-temperature butter turns mushy and will not create layers.
- Whisk the dry ingredients together: 29 g packed whey protein isolate, 30 g coconut flour, 30 g oat fiber, a pinch of salt, 1 tsp gelatin, and 1 tsp xanthan gum. Weight matters here – measuring cups for coconut flour and oat fiber rarely hit the same gram count twice.
- Add the frozen grated butter to the flour mixture. Work it in with a fork so the butter stays in big cold chunks; touching it with your hands starts melting it immediately.
- Start with 5 Tbs ice water and mix with a fork. Add more water a half-tablespoon at a time until the dough just comes together with visible chunks of butter – about 6.5 to 7 Tbs, up to 8 in a warm house. Do not overwork it.
- Press the dough into a rough rectangle on plastic wrap, wrap it, and chill 15 minutes in the freezer (or 30 minutes in the fridge).
- Laminate: dust the work surface with oat fiber (it adds no carbs and does not dry the dough the way coconut flour does), roll the dough out, then book-fold it – fold the edges into the middle and fold over again. Re-dust if it starts sticking, fold once more if it stays cold, then return it to the freezer for 15 minutes. Repeat the fold-and-freeze cycle at least twice, ideally three times, for the flakiest layers.
- Meanwhile, make the strawberry filling: bloom 1/2 tsp gelatin in 1 tsp water, microwave until melted, and stir into 3 Tbs strawberry jam. Chill so it firms up enough to stay put inside the strudels.
- Make the cream cheese filling: mash 57 g softened cream cheese with 1-2 Tbs powdered sweetener, 1/2 tsp lemon juice (optional), and 1/4 tsp vanilla until smooth.
- Preheat the oven to 425 F.
- Roll the chilled dough out thin – about 1/16 to 1/8 inch – into a rectangle roughly 13 x 9.5 in. Trim the edges and cut it into 3 x 4 in rectangles (12 pieces total).
- Assemble: egg-wash the edges of four bottoms at a time so the wash does not dry out, spoon a little strawberry filling and cream cheese filling into the center of each, lay a second rectangle on top, press the edges to seal well, and crimp with a floured fork.
- Brush the tops with egg wash and bake at 425 F for a little over 15 minutes, until golden brown on top and around the edges.
- Transfer to a wire rack to cool for about 30 minutes before icing.
- Make the icing: whisk 3 Tbs powdered sweetener with 2 Tbs heavy cream and 1/4 tsp vanilla until smooth. Pipe or drizzle it over the cooled strudels.
Notes
Servings: 6 (per strudel). Per serving: 204 kcal, ~7 g protein, 13.5 g total carbs, 18 g fat, 11.1 g fiber, 2.4 g net carbs. Calorie/carb/fat/fiber values are from the video description; protein is estimated from ingredient totals.
Quantities: exact from the video description and narration. Only the egg-wash amounts are approximate (1 yolk thinned with a splash of water).
Filling leaks are the classic failure mode. The creator’s tested fixes: cut 3 slits in the top of each strudel before baking, seal the edges with your fingers instead of a fork, or freeze the sealed strudels for a few hours before baking. She also had clean results at 450 F for 14 minutes, and in an air fryer at 390 F air crisp – 8 minutes, flip, 2 more minutes.
The whole batch of puff pastry dough is about 8 g net carbs, so it works as a freezer staple: defrost in the fridge, roll out, and use it for anything you would wrap in crescent roll dough.
