For a girl who lived in Phoenix for as long as I did, I was not made for the heat.

At all.

Though I would laugh at my current self if the old Phoenix me knew that I melt when it’s the high 70’s now. 😀

So the fact that we are in the mid-80’s right now it not my idea of fun.

Nor to my poor little dogs who have heart conditions enjoy it.

The Pacific Northwest used to only get a few days above 80 a year.

And some years it wouldn’t ever reach that.

Which means when all the buildings were built most of them did not come with air conditioning because it wasn’t really needed.

When I moved here I was shocked that there were people who owned cars up here that didn’t come with a/c because it wasn’t standard up here.

Coming from Phoenix I so could not imagine that.

In AZ if I wanted to bake in the summer I would have to wake up super early and bake.

And by summer in AZ I mean March to October. 😛

I find myself having to do that here.

Because while our house has air conditioning it’s not central.

It’s a whole bunch of portable ones scattered throughout the house.

I am super happy we have them but they don’t work nearly as well as central air.

I got up at 5 am because the dogs get me up but I stayed up to make this Mixed Berry Cornbread Dump Cake.

Dump cakes are easy and so I make them often.

This one takes a little more time because it uses fresh berries instead of buying canned.

If you want to use canned berries you will need about 3 cans of 20 oz mixed berries.

While I don’t normally use Jiffy cornbread I used it in this because it’s less coarse in texture.

Cornbread can be coarse and while I like the texture not everyone does which is why it’s combined with yellow cake mix as well.

If it’s warm where you are I hope you can stay cool.

And as always it’s a great day to order my cookbook.
