Best Ever Peanut Butter Sheet Cake

Peanut-Butter-Sheet-CakeThis is the best peanut butter cake I’ve ever baked.  Richard loves peanut butter, so I’ve made several attempts over the years for a successful recipe.  To me, there’s never been enough peanut butter flavor, but this one did not disappoint.

It’s a rich sheet cake with a yummy peanut butter frosting that you cook on the stove top in a jiffy and pour over the warm moist cake.  You get plenty of creamy fudge-like frosting with each piece.  The directions for this recipe are a little different for me.  You boil the peanut butter, butter, and water before added to the dry ingredients.  No creaming the butter and sugars.  Sure makes for a nice moist cake.

This recipe calls for a “jelly roll pan.”  A little search on the Internet and I learned that a standard size is 15″ x 11″ x 1″, but I found others as large as 12″ x 17″ x 1″ basically a cookie sheet/jelly roll pan.  I was afraid the larger pan would make the cake layer too thin.  I’ve also tried sheet cake recipes where there was so much batter, the cake spilled over the sides of the pan as it began to bake, and dribbled on the oven floor.  I love sheet cakes – I hate to clean the oven.

I ventured out and found a 15″ x 11″ x 2.5″ Wilton sheet cake pan – Perfect!  The cake won’t rise all the way to the top of the pan, but it doesn’t have to.  I just didn’t want to clean up a mess.  And I’ll be using it for all my other sheet cake recipes.

Honestly, I can’t stop eating this cake.  It’s sitting on my kitchen butcher block, and I have to find something else to occupy me or I’ll get a fork and whittle away right out of the pan.  Hope all you peanut butter lovers will give it a try.
