   • In a mixing bowl, combine the egg yolks, whole eggs, salt, and baking powder. Use an electric mixer to whisk the mixture until it becomes thick and forms a trail when you lift the whisk.
   • Gradually add the keto-friendly cake flour to the egg mixture at the lowest speed. Mix just until combined.
   • Slowly incorporate the melted unsalted butter into the batter, folding gently until fully combined.

2. Bake the Cake:

   • Preheat your oven to 200°C (392°F).
   • Line a 28 x 28 cm baking tray with baking paper and pour the batter evenly into the tray. Gently tap the tray on the counter to release any air bubbles.
   • Bake for approximately 12 minutes or until the cake is lightly golden and springs back when touched.

3. Prepare the Filling:

   • Drain the canned tuna thoroughly. If you prefer a drier filling, you can sauté the tuna in a pan until slightly crispy.
   • In a bowl, combine the drained tuna with mayonnaise, sweetener, and a pinch of salt. Mix well and refrigerate until slightly set.

4. Assemble the Swiss Roll:

   • Once the cake has cooled slightly, carefully invert it onto a clean kitchen towel. Peel off the baking paper.
   • Spread the tuna mayo filling evenly over the cake base.
   • Using the towel, roll the cake tightly from one end to the other. Allow it to cool completely, about 10 minutes.

5. Set the Roll:

   • Wrap the rolled cake in the kitchen towel and place it in the freezer for about 30 minutes to help it hold its shape.

6. Slice and Serve:

   • Remove the Swiss roll from the freezer, unwrap it, and slice it into desired portions. Serve immediately or store in the refrigerator for later.

Notes

• Ensure you tap the baking tray before placing it in the oven to remove any air pockets; this step is crucial for achieving a dense texture.
• If you prefer a thicker cake, you can use a 26 x 26 cm baking tray instead.
• Each slice contains less than 0.5 net carbs, making it a guilt-free treat to enjoy!

This Swiss roll tuna mayo is a fantastic addition to your keto recipe repertoire. With its fluffy cake and savory filling, it’s sure to impress friends and family alike while keeping your meals exciting and delicious. Enjoy!
