Peanut butter and banana has to be one of THE best food combinations of all time (alongside cake and pretty much everything).

I love cake. And I love cake decorating. But sometimes I am just not in the mood. I can’t be bothered to whip out my off-set spatula and a big batch of buttercream or ganache and spend a few hour on meticulous frosting.

Loaf cakes or banana cakes in general are one of my definite go-to’s for a lazy but not too lazy bake and an addition of peanut butter makes this cake super moist and yummy.

If you want to go the extra mile like me (yup, this is becoming less and less of a lazy bake), top this beauty with some caramelised bananas and a peanut butter glaze! Even though they are technically “extra” effort, they are super easy to whip up and take this loaf cake to the next level and, anyways, you might as well do something while the cake is baking.

Probably the best thing about this cake and all non-frosted cakes is that I don’t have to wait until it’s completely cooled. Warm banana cake is one of life’s finer beauties.

Plus, let’s be honest, is there anything more indulgent than peanut butter? Well, that is, aside from chocolate, of course. Just show me a huge tub of generic brand crunchy PB and my heart starts going mental and my eyes dilate. True love.

The cake’s texture has a perfect crumb; fluffy, spongy and light which saves this cake from being too rich.

So please, for the love of everything wonderful in this world, bake this baby! Check out the original post HERE and for more indulgent recipes, click HERE.
