Peanut Butter Sheet Cake with Chocolate Glaze

Peanut Butter Sheet Cake with Chocolate Glaze

I am going to sound like a broken record saying this, because I have said it a million times before, but there is no better combination in the world than peanut butter and chocolate. This Peanut Butter Sheet Cake with Chocolate Glaze is a delicious dessert that is perfect for parties and get togethers. Because it is a sheet cake, it bakes much faster than some other cakes, and it is much more convenient to serve.

Tips for making my Peanut Butter Sheet Cake with Chocolate Glaze:

  • You can use a regular creamy peanut butter, or natural. I do not recommend using crunchy because the nuts will probably all settle at the bottom of the cake.
  • When you are mixing the wet ingredients together, it will seem VERY liquidy. Also, the peanut butter may not fully combine with the other ingredients. Both of these things are okay and to be expected.
  • Whatever you do, DO NOT overcook your cake! There is nothing worse than a dry cake.
  • Let the cake cool slightly before adding the glaze, but the best thing about using a glaze rather than an icing is that it pours on, so the cake can still be warm when topping it.
  • I know waiting is hard, but do your best to allow this cake to cool before slicing. You don’t want it falling apart on you!
