Cake Mix Cookie Bars for Summer

There are so many fun Patriotic desserts out there, this super easy cake mix cookie bars are perfect for any summer outing. 

We made these patriotic cookie bars for my son’s send off to the USAFA a few weeks ago, and obviously they would be great for Memorial Day, Fourth of July and Labor Day desserts. 

Obviously you don’t have to use red, white and blue sprinkles and you can use any sprinkle you have on hand. 

We have made a few different cake mix bars like these double chocolate cake mix bars and sprinkle blondie cake mix bars.


Since we were going with red white and blue, we chose a white cake mix for our base of our simple cookie bars.

For a bit of chocolate flavor and additional white throughout our bars we added white chocolate chips.

The batter of these blondie cake bars should be thick, otherwise you will have more of a cake bar,  I did this the first time. They will taste fine, but just very cakey.

We prefer these with a little cookie crunch. 

What you need to make Patriotic Funfetti Cake Mix Blondies

Can I freeze Cake Mix Blondies

Yes, we made them a few weeks before our event.  Allow the entire block of cookie to cool and then freeze in tact.

We wrapped it in tin foil and then placed it in a freezer bag. 

Allow the block to thaw almost all the way,  then cut.  If you are cutting smaller pieces it may be easier to cut it while it is still slightly frozen.

If you just want to eat slices and not serving to a crowd,  cut into individual slices, wrap and freeze. 



Will you bring these to your next Fourth of July Picnic?
