Why I Love these Marshmallow Blondies!

These awesome blondies are quick to make, and have a simple base.  The marshmallow melts into the blondies and also get golden toasty  on top, making them even more irresistible? Seriously….yes I know, I said that before, but seriously!!

I know this, because they will magically disappear right before your eyes mouth, never to be seen again. Hide and seek into thy mouth!  

And it’s all Annalise Thomas‘s fault, right there, as plain as the nose on your face, “Butterscotch Marshmallow Chocolate Chip Blondies” on page 99 of her brand new cookbook “The Make-Ahead Kitchen“.

What I love about her cookbook is, it’s stocked with 75 fabulous Slow-Cooker, Freezer, and Prepared Meals for your busy lifestyle, which is pretty much how life is, right?  She has her own personal tips that she also shares with you. Her style of writing is genuine and guess what? She uses salted butter in her baking recipes — she’s classic old school.

 The food photography is amazing and I’m committing myself to make so many of her delicious recipes because I DO have a busy lifestyle, and this cookbook makes perfect sense to get ahead of the game, and not be rushed. Thank you Annalise!

I did modify Annalise’s recipe, only because I have an intense obsession for marshmallow and Reese’s Peanut Butter Cups, so I doubled the marshmallow and added in the peanut butter cups.
