I am so happy for Becca that she is about to marry the man of her dreams. While I have not met them personally, it truly seems that although she has been through some ups and downs, he has stuck by her and supported her through it all. That is so special and amazing. So to celebrate this wonderful event, a group of us came together to throw Becca a Virtual Wedding Shower. With as amazing as my foodie friends are, you know we are in for a delicious party! Make sure you check out what’s on the menu at the bottom of this post. And also stop by to see her on Facebook and say, “Congrats!”

Beccas Virtual Bridal Shower

What could be more fun than a Halloween wedding?! I have told Becca that Halloween is a great day to get married – my aunt and uncle were married on Halloween, and now, over 25 years later (26? 27? Geez, I forget), they are as happy as ever. And it is already such a festive day – the crisp fall air, excited anticipation, laughter and joy. And chocolate. Definitely the perfect recipe for an amazing wedding day.

And what could be more fun than colorful, chewy, chocolaty, delicious cookies?!?!

And besides fun, these monster brownie cookies couldn’t be easier or faster to make!

Perfect for when the kids tell you the night before that you have to bring cookies to their class Halloween party the next day. Add a few ingredients to your favorite brownie mix, scoop them out onto a tray, and press in your favorite General Mills Monster Cereal pieces and marshmallows. Naturally, the kids’ cookies will end up looking like this…

    The good news is they taste great. The bad news is they spread waaaaaay too much. Mine dont look like this at all. Not sure I would try again. Sad face.
