Make the protein cream

• Spoon the Greek yogurt into a bowl.
• Add the protein powder and whisk until smooth and thick.

Dip the biscuits

• Pour the cooled espresso into a shallow dish.
• Dip each ladyfinger briefly so it is soaked but not falling apart.

Layer the tiramisu

• Place a layer of soaked biscuits in a glass or dish.
• Spread half of the protein cream on top.
• Repeat with the remaining biscuits and cream.

Chill

• Cover and refrigerate so the layers set.

Finish and serve

• Dust the top with cocoa powder through a sieve.
• Top with sliced strawberries and serve.
