There's a Dutch Sugar Lump Loaf recipe in this 1972 newspaper article.

Here is a link that might be useful: Dutch Sugar Lump Loaf

Thank You, ginger_st_thomas. Might be it, but i can not open it......

SUGAR LUMP CINNAMON BREAD

1 cup milk
½ cup margarine
½ cup sugar
1 teaspoon salt
2 packages yeast
1/3 cup warm water
1 tablespoon vanilla
1 egg
5½ to 6 cups flour

Combine milk, and margarine and heat to scalding. Add sugar and salt and cool to lukewarm. Soften yeast in 1/3 cup warm water. Add vanilla and egg to milk mixture. Add softened yeast. Add flour gradually as needed. Knead dough on floured surface until smooth. Let rise until double. Punch down and divide in half. Roll each half to 12 by 15 inch rectangle. Mix ¼ cup soft margarine or butter, 1 tablespoon cinnamon and 50 sugar cubes. Mix together. Use half on each rectangle, spreading as evenly as possible. Roll up and pinch edges to seal. Place in greased bread pan and let rise until double for 30 to 35 minutes. Bake for 30 to 40 minutes at 375°.

It's from an interesting website called Open Line which apparently is a radio cooking call-in show in Iowa, going back many years. This recipe is from their 1971 Bulletin.

I was able to pull up the link, and tried to C&P but it didn't work real good, it didn't come out as a single column but rather as a jumble of all the columns on the page. Someone would need to read and type the recipe off the site.
