Okay... I'm back with the recipe, Alix.
(I dont know if you are even interested, but I'll post it anyway) This recipe includes the brownie batter, but I'm sure you could use your favourite brownie batter recipe and then just use the blueberry cream cheese filling with it.
GrumbleBee's Blueberry Cream Cheese Stuffed Brownies
Ingredients for brownies:
1/5 cup butter
1 cup chopped dark chocolate
2 cups sugar
2 tsp vanilla extract
4 large eggs (I've tried with less and the texture isnt as nice)
1 and 1/2 cups regular, white flour
1/2 tsp salt
Ingredients for blueberry cream cheese filling:
1 and 3/4 cup softened plain cream cheese
1/2 cup sugar
1 tsp vanilla extract
1 large egg
Blueberries (fresh or frozen and thawed... measurements are up to you... i think i use about 1 and 1/2 cups)
Make the Cream Cheese filling first.
Blend the cream cheese, sugar, egg and vanilla extract in a mixer until smooth and creamy. Then add half the blueberries and blend some more. This should break the blueberries down a bit and start oozing out the juices, so that you get that luscious purple colour. When that is done, stir through the remaining blueberries so that they stay whole in the mix. Add more blueberries at this stage if you wish, I did. Set mix aside.
To make the brownie mix. Blend eggs, sugar and vanilla extract in a mixer until light and fluffy. Melt the butter in a saucepan and add the chocolate, stir over a low heat until smooth and glossy. Beat chocolate butter mixture into the egg mixture. Lastly stir in the flour and salt. You should have a gorgeous sweet chocolate batter.
Next it is all about the layering. Put half the chocolate mixture into a lined slice pan and spread out evenly. Then add all your cream cheese filling across the top of the chocolate mixture, spread that out to make a nice even layer. Then add the last of the chocolate mixture on top. Spread out evenly. The cream cheese filling might mix a little with the chocolate mixture - that's okay! Then bake in an oven for 40 minutes. Turn off the oven and allow them to cool completely in the oven. Lastly dust with some icing sugar and your done.
They are so good!
