Ingredients
Scale
- 6 Large egg whites (room temperature)
- 1/3 cup Granulated sugar or monk fruit sweetener
- 3 Large egg yolks
- 1/2 cup Low-fat vanilla Greek yogurt
- 3/4 cup All-purpose flour
- 2 tablespoons Cornstarch
- 1 teaspoon Pure vanilla extract
- 1/2 teaspoon Baking powder
- 1/4 teaspoon Sea salt
- 1/2 cup Low-sugar fruit jam or preserves
- 1 cup Fresh mixed berries
- 1 cup Greek yogurt (for filling)
- 1–2 tablespoons Powdered sugar (optional, for dusting)
Instructions
- Preheat your oven to 375°F (190°C) and position the rack in the upper-middle position for even browning.
- Line a 10 by 15-inch jelly roll pan with parchment paper, ensuring it extends slightly beyond the edges for easy removal.
- Lightly coat the parchment with cooking spray or brush with neutral oil to prevent sticking during baking.
- Separate your eggs carefully, ensuring absolutely no yolk gets into the egg whites, which prevents proper whipping.
- Add the six egg whites to a spotlessly clean bowl and beat with an electric mixer on high speed for two minutes until foamy.
- Gradually add half the sugar while continuing to beat, then add the remaining sugar slowly, creating stiff peaks that hold their shape.
- In a separate bowl, whisk together the three egg yolks, Greek yogurt, and vanilla extract.
- Sift together the flour, cornstarch, baking powder, and salt, then gently fold into the yogurt mixture using a rubber spatula.
- Carefully fold one-third of the whipped egg whites into the batter to lighten it, then fold in the remaining whites in two additions.
- Pour the prepared batter onto your parchment-lined pan and spread evenly using an offset spatula.
- Bake for 10 to 12 minutes until the top springs back when lightly touched and a toothpick inserted comes out clean.
- While still warm, turn the cake onto a clean kitchen towel dusted with powdered sugar to prevent sticking.
- Peel away the parchment paper carefully, working from one corner across the surface of your warm cake.
- Starting from the short end, tightly roll the warm cake in the kitchen towel, creating a traditional spiral.
- Allow the rolled cake to cool completely, approximately 20 to 30 minutes, resting seam-side down so it maintains its shape.
- Gently unroll the cooled cake onto a clean work surface, handling it delicately to prevent cracking.
- Spread the low-sugar jam evenly across the cake surface, leaving a quarter-inch border around the edges.
- Distribute the fresh berries over the jam in an even layer, adding natural sweetness and nutrients.
- Combine the Greek yogurt with a tablespoon of powdered sugar if desired, creating a spreadable consistency for the topping.
- Spread the yogurt mixture over the berries, sealing in the filling.
- Starting from the short end again, carefully roll the cake, using the towel to guide it into a tight spiral.
- Wrap the completed jelly roll tightly in plastic wrap and refrigerate for at least one hour before slicing and serving.
Notes
- Beat egg whites until they form stiff, glossy peaks; underbeaten whites won’t support structure, while overbeaten become grainy.
- Keep hands and equipment scrupulously clean when handling eggs, since even microscopic amounts of fat prevent proper whipping.
- Fold egg whites gently using a spatula in broad strokes from the bottom of the bowl upward to maintain air bubbles.
- Roll the warm cake immediately after removing it from the oven while flexibility remains to prevent cracking.
- Use a serrated knife dipped in hot water and wiped clean between cuts when slicing to create clean edges.
- Serve chilled, as cold temperatures firm the yogurt and jam, making each slice hold its shape beautifully.
