Method

1️⃣ Whisk

In a separate bowl, mix the self-raising flour, Whey Protein Isolate Vanilla, baking powder and salt.
Slowly fold the dry ingredients into the wet mixture until fully incorporated.

4️⃣ Divide & Bake

Divide the batter evenly between two small lined cake tins.
Bake at 170°C for approximately 60 minutes, or until a skewer comes out clean.
Allow to cool completely before icing.

5️⃣ Prepare the Icing

Beat the cream cheese on low speed until smooth.
Gradually add the icing sugar.
Increase speed and beat for 2 minutes until light and creamy.

6️⃣ Assemble

Spread icing between the two cake layers, then cover the top (and sides if desired).
Slice and celebrate.

FAQs about Birthday Vanilla Whey Protein Cake

Can I use another protein flavour?

Yes. Vanilla works best for a classic cake base, but you can experiment with other flavours depending on the result you want.

Will the protein make the cake dry?

Not with the yoghurt and oil included. They help maintain moisture and structure.

Can I make it as cupcakes instead?

Absolutely. Reduce baking time to around 18–25 minutes and check with a skewer.

How should I store it?

Store in the fridge due to the cream cheese icing. Best enjoyed within 3 days.
