So summer tv is pretty lousy, am I right? There’s just not much on, with the exception of wonderful guilty pleasures like ‘The Bachelorette’.

To make up for the lack of interesting things to watch recently, I finally jumped onboard the Downton Abbey train.

Hooked, I tell you! I finally finished the fourth season last night.

Honestly, I found the end of the fourth season to not be nearly as exciting as the ends of seasons two and three, but certainly less depressing than the end of season three.

When the hubs was out of town last weekend, I was constantly at war with myself over whether or not to bake or watch Downton Abbey. Most of the time I tried to multitask and do both.

At one point, I won’t say what happened in case you haven’t watched it and don’t want to know what happens, I was crying over the loss of a pretty major character when the hubs called. He’d just left from visiting his family. His mom was crying as he left, as mom’s often do in our experience, and when I answered crying he was like ‘what is going on with all the crying?’ 🙂

If you haven’t seen it yet, you should totally catch up. I laugh, cry and everything in between. I am always thrilled when the grandmother comes on. I don’t think there’s ever a scene with her that I don’t laugh and want to rewind to see it again. I love her little comments. Always so perfect. I wish I was as clever as her. 🙂

It’s been a while since I shared my last cookie cake. I love the fun variations and alternatives to a regular cake. Plus, they are super easy to make! Even better than making cookies because you don’t have to make a bunch of balls and do multiple rounds of baking.

Customize Your Lemon Cookie Cake

The lemon flavor in this cookie comes from fresh lemon juice and lemon zest. I considered adding a lemon pudding mix, but decided against it. You totally could add it if you want, but I decided I wanted a little lighter lemon flavor.

And I added white chocolate chips, because I love them, but that would be optional too. It’ll be tasty either way.

If you love lemon as much as I do, there’s no doubt that you’ll love this cookie cake. It’s fresh tasting and not overwhelming at all. Lemon cookie heaven!
