I made this for my family for our Mothers' Day cookout and everyone LOVED them. I Used blackberries instead of blueberries (I don't like blueberries..) and I added a sprinkle of sweetened coconut shavings to the top of half of them to try it out, and it was a big hit, added a nice little extra sweetness. I don't remember which angel food cake mix I used, but it came out perfect, nice and fluffy!
I will definitely be making these to share with my friends later this summer!
