Sourdough Sharing - Brownies

This month's sourdough challenge was brownies.  I decided to try a blondie recipe that I have made in the past and a new brownie recipe.

Now I love to eat them - both brownies and blondies but often seem to have trouble with the centres falling.  Help anyone?  It doesn't seem to matter which recipe I try (regular or sourdough) my brownies often have a cakelike texture around the edges and are almost sticky in the centre.  If I bake them longer, the edges get too dry with the centre usually not being much different from before (just a little more cooked).  Ideas?  Suggestions?

My brownies were taken from Rita Davenport's Sourdough Cookery book.  
Chocolate Peanut Butter Brownies.

Ingredients
1/4 c butter
2 squares unsweetened chocolate (I substituted 3 Tbsp cocoa and 1 Tbsp butter for each square.)
1 c sugar
1/4 c peanut butter (I used chunky)
2 eggs
1/2 c sourdough
1 tsp vanilla
1/2 c flour
1/2 tsp baking powder
1/2 tsp baking soda

You are to melt the butter and chocolate over low heat.  Then add sugar and peanut butter.  For this step, I just used very soft marg. and my mixer.

 

Add eggs, sourdough and vanilla.  Mix dry ingredients and stir into batter.

 

Spread in a greased 9" x 9" pan.  Bake at 350°F for 20 to 25 minutes.  Cool and then frost, if desired.  I don't usually frost mine.

 

Here you can see the sunken middle.  :(

 

Here is one middle piece and one edge piece.  The brownies taste great with the chocolate and the peanut butter.  I will try them again, once I get help with the sunken middle problem.



The blondies are from a Robin Hood Flour pamphlet on sourdough.
Sherwood Blond Brownies

Ingredients
1 c brown sugar
1/2 c sourdough
1/4 c butter, melted
1 egg
1 c flour
1/2 tsp baking soda
1/2 c chopped nuts or coconut

Beat together sugar, sourdough, butter and egg.  Again I used softened not melted butter.  (You don't think that is my problem, do you?)  Add in the rest of the ingredients and mix well.

 

Spread batter in a greased 8" x 8" pan.  Bake at 350°F for 20 to 25 minutes. 

Again you can see the dropped centre.  It is not as bad as the chocolate ones, though.

Again you can see how much higher and drier the edge piece was compared to the middle piece.  These taste great with the brown sugar and nuts - a nutty butterscotchy flavor.
