Peanutbutter isnt  a stapel here and it is a bit on the expensive side of things so I need a tried and true recipe of a sponge cake that had peanut butter in the batter and if  it possible one that also has chocolate.

My daughter has dreamed up a cake with  peanut butter chocolate sponge and tablet topping, tablet I can do but I dont have the recipe for the sponge.  Oh and she wanted to use bacon powder to in it, but I think we can skips that.

Could you please help me?

Hmm.  I don't have a recipe with chocolate and peanut butter in it.  I've had a good amount of success using the modified cake mix recipe with butter cake mix and adding peanut butter to it.  You could do a chocolate/peanut butter marble!  

Sift together:

1 yellow cake mix

1 c flour

1 c sugar

1 t salt

Add:

1 1/3 c water (sometimes I add more if the batter is really thick)

3 eggs

1 c sour cream

1 T vegetable oil

1 c peanut butter

1 T vanilla 

Mix and place in pans.  Makes a little over enough for 2 8" rounds.  Bake about an hour at 325 degrees.  

PS - you could try this with chocolate cake mix instead.  I bet that would be yummy.

PPS - I have used PB2 (peanut butter powder) too if you have that available, although I can't remember how much.  They make a PB2 with chocolate and peanut butter too.  

At my last cooking position we used the  white commercial Pillsbury cake mix and added a cup of creamy peanut butter. Everyone loved it. I have not tried making a scratch one yet.

Cake mixes  is rare here and if I find it, it is way to expensive for me and peanut powder I have never seen, so I am back on looking at the net.
