With summer upon us graduations, pot lucks, picnics, barbecues, and family gatherings are in full swing. With every new summer I like to create new desserts or tweak ones that I have found. Classic desserts are great, however I found that tweaks can be just the thing for a new and perfect summer dessert.

If you are like me, and are looking for a new dessert recipe to try out this summer this peanut butter cake and icing will be one of the most moist cakes you have ever had.

Peanut butter lovers will continue to come back to this melt in your mouth peanut butter cake. This recipe is super easy and simple to make, created from a simple yellow cake mix it could not be easier.

Preparing Peanut Butter Icing:

  1. In a small sauce pan whisk together flour and milk and stir constantly until it thickens (You will want it to be very thick almost like brownie batter).
  2. Remove from heat and let cool to room temperature, add in vanilla.
  3. While this is cooling cream peanut butter and sugar until light and fluffy.
  4. Add completely cooled flour/milk/vanilla mixture to the creamed peanut butter/sugar and beat it until it is completely combined (If it looks separated you didn't beat it enough).
  5. Frost on cooled cake.

If you wish, this cake can be topped with crushed nuts or even a brown sugar/flour streusel. The cake pictured has neither of these two extras, however I have made it with both of these extras together and it tastes just as good with or without them.

The moist melt in your mouth peanut butter cake topped with a thick and rich peanut butter icing is sure to be a crowd pleaser. Do not be surprised if you have nothing to take home, it always seems to disappear at the functions I take it too.
