Black Forest tray bake - recipe

This Black Forest tray bake was a thrown together affair and I made it up as I went along, I wanted a quick easy cake to give to some of the family yesterday; but it worked a treat and tasted good so here is the recipe...just keep an eye on your baking times...if its shrinks away from the sides and has no wobble in the centre its done.

I used frozen loose berries that I had bought from my local supermarket where they sell them loose, a packet or box of frozen berries will do. We ate this as it cooled after baking...the chocolate and sharp hit of some of the fruits were a nice mix.

Ingredients:
4 medium free range eggs - beaten
225 g soft margarine
225 g caster sugar
1/2 tsp vanilla paste
25g ground almonds
50g cocoa powder
150g self raising flour
1 tsp baking powder
2 tbsp milk
approx 400g frozen berries (Black/red currants, raspberries, blackberries - that type of thing)
Method:
1. Pre heat the oven to 170C fan. Grease a deep sided tray.

2. Sift the flour, baking powder and cocoa powder in a bowl and then mix in the ground almonds. 3. Cream the margarine and caster sugar until pale and then gradually beat in the eggs, add a tablespoon of the dried ingredients mix if this starts to curdle. Add the vanilla paste and mix again.
4. Fold in the dry ingredients mix until just combined. Add the milk to loosen the batter.
5. Put the batter into the baking tray and spread out with a pallet knife or spatula. Add the frozen berries to the top as evenly as you can.
6. Bake in the oven for about 35 minutes.
7. When baked dust with icing sugar and cut into squares to serve.
