Recipe: Berry Buttermilk Slice

Back in January we ran a morning tea fundraiser at work for bushfire relief so obviously I had to take something along. This berry buttermilk slice was my contribution and it didn’t stick around for long, so I took that as a very good sign! It’s not too sweet, simple to whip up and all happens in one bowl – my kind of baking!

  3. Add the eggs one at a time, beating well between each addition
  4. Add the flour and buttermilk in two batches, until smooth

This berry buttermilk slice takes a little while in the oven, but the actual hands-on time is pretty limited, which is excellent. I recommend letting it properly cool before cutting it so it keeps its shape. It’s also best to use berries straight from the freezer so they don’t ripple the batter, but at the end of the day it all tastes the same!

I think it’s safe to say this berry buttermilk slice is going to be high on my regular-baking list pretty quickly. It doesn’t hurt that it gives me an excuse to make pancakes with the remaining buttermilk too!

Any combo of berries will work as well – I went with a mix of blueberry, raspberry and blackberry this time but just raspberry would be excellent as well. Basically whatever you have in your freezer will be delicious!
