    I love butterscotch.  I love cake.  And that is the inspiration for this Butterscotch Peanut Butter Cake!

    Peanut Butter Cake

    I made a peanut butter cake.  It’s a GOOD peanut butter cake! Soft and moist and full of peanut butter. Then I made a butterscotch sauce infused with peanut butter.  Then I busted out a can of marshmallow fluff.

    Ready for the details?

    Bake cakes and let them cool.  Place one cake on cake stand and spread an entire 7ounce jar of marshmallow fluff.  Place the other layer on top.  Marshmallow will ooze out the sides.

    This is good.  Very good.

    Next, make the butterscotch sauce.

    Put a thin layer of the sauce on top of the cake.  (This is to help the mini marshmallows to stay in place) Then disperse mini marshmallows all over the top of the cake.  (I used about half a bag)

    Pour sauce over cake.  Now, at this point in the picture, I had poured about half the mixture.  This is plenty for the cake.  The remaining mixture you can put in an 8×8 pan and make butterscotch bars! (Just make sure you mix in the remaining marshmallows first)

    I highly recommend you do that instead.  Or you could just half the recipe.  I mean, whatever works for you.

    But I did not do that.

    I kept pouring.  And scooping out the chunky bits.  And pouring.  And I made a HUGE mess.

    I just couldn’t stop.

    Don’t be like me.

    But do grab some of those butterscotch-y peanut butter chunk-y bits from the bottom of the pan and spoon them over the top of your cake.

    Then, out of seemingly nowhere,  I had visions of butterscotch hot chocolate with mini marshmallows but did not want to do that if it was 75 degrees outside.  Maybe on the next nice cool day, I could.  And then the temperatures went from 75 to 30 in one day and I actually made myself a hot cocoa.  And then I felt bad and figured I caused the cold temperatures so I didn’t tell anyone.  Except now I am telling you.  Don’t be mad.  It will get warm again.  I think.  I mean, I cant say for sure.  I live in Minnesota.  We are known for weird weather.  So yeah.

    Moving on.

    Or save some of that awesome sauce and drizzle it over a slice.  I wish I could say that I had thought of that before pouring rich thick butterscotch sauce all over my white linens and table.

    Did I mention I made a big mess?

    It was sorta worth it.  This cake is delicious.

    3. Bake in two prepared 9-in round cake pans at 350 for 25-35 minutes.
