Have you ever made millefeuille? The name might be intimidating (it's French for "a thousand layers"), but this version of the dessert is so easy that even the littles can help with it! I got the idea here, and made a few changes since we had just gone blackberry picking.

First, start with a sheet of frozen puff pastry, following the instructions for thawing. Roll it out into a rectangle, and cut the rectangle into three equal pieces (I used a pizza cutter to make this easy). Put the pieces on a baking tray lined with parchment paper or a silicone sheet, and poke them all over with a fork to make sure they don't get too bubbly.

Sift powdered sugar on top to help them caramelize in the oven.

Bake them at 425 degrees for 12-15 minutes, until they're puffy and golden-brown.

Make a whipped cream (or use store-bought!) with whipping cream and powdered sugar. We also added blueberry nectar to make it a pretty lavender color! Layer the whipped cream on top of one of the pastries, and add whatever summer berry you'd like on top (we used blackberries). 

Stack the next pastry on top, and keep going! When you're done, sift some more powdered sugar on the top. The dessert is so fresh and light, and not overly sweet! And it looks much trickier than it really is, so it's a fun one to do with the kiddos for a party. 

I'm already dreaming about more flavor combinations! I think a Nutella-whipped cream with strawberries might be next for us. :)
