88 All-Time Best Dinner Recipes

I always use 2 cans pineapple crushed, 2 box pistachio pudding mix, half or 3/4 bag mini marshmallow, and large bowl cool whipped. Chopped pistachio nuts bout 1/2 cup and 1/2 cup sprinkled on top. Always chi mine at least 2 hours before serving. It's a must have foe holidays or picnics. First bowl emptied and gone. Kids favorite. Kid friendly to help add and stir ingredients together. Kids like flavored or colored marshmallows instead regular. Remember Always Enjoy.

The recipe looks good, I am just wondering if it is do able with gluten free flours and how much say of brown rice flour would I use. Also could I use buttermilk instead of regular milk?
