Hello...New poster but old lurker here LOL Anyway, saw your request and believe it or not MY MIL gave me this recipe at least 30 years ago and may be the one you are looking for. Have not thought of it in years and may just make it myself this year.
IceBox Fruitcake
1 pound vanilla wafers crumbed fine
1 pound miniature marshmallows
1 can sweetened condensed milk
1/2 pound butter
1 quart nuts (4 cups) pecans and brazils coarsely cut up
1 8 oz package candied pineapple red and green
1 4 oz package candied pineapple yellow
1 16 oz package candied cherries red
1 4 oz package candied cherries green
1 16 oz package mixed fruit
1 can coconut

Warm milk - open and set in hot water
melt butter, and add to warm milk in large bowl
add vanilla wafer crumbs. Mix with all fruits, nuts, coconut, and marshmallows.
Mix well. Best tool for this is your hands.
Line pan with wax paper and pack mix in lightly. Refrigerate for a day or so and store in refrigerator.

Any size pan will work, tube, loaf, bundt.

Thank you for making me remember this recipe. It is really good.

My mother used to make this with the graham crackers and she always melted the marshmallows with the milk in the top of a double boiler until completely melted and then poured this over the crackers, fruits, and nuts. Mixed well and packed into a buttered loaf pan. Then removed from pan and wrapped with wax paper and then stored in the refrigerator. The longer it lasted the better it was. Glenda

I made this one once several years ago - we liked it, but it made a huge batch, and was almost too rich (and that's not normally a problem for me LOL). I haven't frozen it, but the recipe I have included those instructions, so I'm passing them on for what it's worth.

My grandmother's recipe is similar to the Eagle Brand Jeweled Fruitcake. Instead of mincemeat, she used chopped dates and all the candied fruit was chopped. I'm sure you could use vanilla wafers in place of the graham crackers. If you use the Eagle Brand Jeweled recipe's combined measurement of candied fruit you could add whatever you remember from the past just as long as you use that amount. My grandmother's says 2 c. candied fruit and one package of chopped dates. She used the marshmallows uncooked. After mixing all the ingredients by hand she pressed the mixture into a wax paper lined loaf pan with another piece on top used to press it in good. I use little loaf pans and give them to my children at Christmas time. You should refridgerate it for a couple of days and serve thin slices because it is so rich. Its not meant to eat in thick slices. Hope this helps. The first time I remember eating this was Christmas 1946. Write me if you want my grandmother's recipe.
