So, if you guys follow me on Snapchat (find me at bunsinmyoven1), you probably already heard about the drama that happened last week.

My husband works out of state, about 3 hours from home. He’s home every Friday night and heads back to work on Monday mornings. Since last week was a holiday week, he was only at his apartment from Monday until Wednesday, so we let the kiddos go up with him.

The plan was that the kids would stay in his apartment while he worked and then they’d get some good dad time in the evenings.  They’re 15 and 10, so they’re perfectly capable of being home alone all day and they were pretty excited about the idea of playing video games alllllll day long without me around to ask them to take out the trash and empty the dishwasher.

Of course, Monday evening the ten year old got sick. She was up all night, every 30 minutes, doing gross things that I won’t talk about on a food blog because ew.

I was super sad for her, obviously. But, let’s have some real talk for a minute, shall we?

My husband has never in his life had to deal with a sick kid on his own. He has never pulled a night shift with a puker. He has never, not once in his life, called in sick to work to take care of a child. That’s Mom territory in our house. Except this time, Mom was 3 hours away, blissfully sleeping in her cozy bed, drinking glasses of wine, eating cheese for dinner because there was no one demanding she cook, and basically enjoying the crap out of the single life.

I have never laughed so hard about anything in my life. My poor husband. It was a shock to the system, I think.

Anyway, that’s the story of how I won at life last week. Fingers crossed no one else ends up sick!

Now, let’s talk about Christmas cookies! It’s time, guys. I can not wait another second to share these peanut butter oatmeal bars! I took my favorite monster cookies, doctored them up with some Oreo cookies and peanut butter m&m candies, and turned them into a bar. I love this cookie base because it’s infinitely soft and chewy. It’s my favorite cookie base in all of the land and it gets made more often than I’ll admit. We eat the heck out of some monster cookies in this house and now we get to make them Christmas-y! Yay!

Promise me you’ll make these cookie bars! And also, let me know who pulls the night shift in your house when there’s a sick kid. I’m curious if it’s mostly the mamas or if the dads get in on the action, too!
