Devour this coffee walnut streusel cake on Father's Day

Posted by Lauren Scaroni on

I thoroughly enjoyed making this easy and delicious Coffee Walnut Streusel cake on Sunday morning to share with my family.

I used the beautiful and Certified Fairtrade Organic Sunshine Coast Blend (our coffee of the month) in the ingredients and substituted the flour with cassava flour for a gluten free cake.

The Streusel, lightly sweet and nutty, paired beautifully with the Sunshine Coast Blend's buttery chocolate and almond flavours.

It was devoured quickly, so I had to be quick to grab this photo.
