In a bowl first mix the dry ingredients: flour, cinnamon, nutmeg, baking powder, salt and sugar.
Then add the olive oil, about 1 cup of the frozen berries, the sourdough discard and eggs. Mix well.
Grease the loaf pan.
Fill the dough into the loaf pan.
Scatter the second cup of berries onto the top. Sprinkle with a bit of sugar.
Bake the cake in the oven for about 1 hour 15 minutes.
Once the cake has cooled down, prepare the cream cheese frosting: in a bowl mix the butter, cream cheese, vanilla extract and pink food coloring. Cream well until you have a smooth frosting.
Spread the frosting on the cake. Decorate with sprinkles if you want to.
