The batter is a creamed butter cake made moist with half a cup of sour cream. Half goes into the loaf pan, then most of a pecan, brown sugar, cinnamon and melted butter mixture, then the rest of the batter.

A light swirl pulls the pecan ribbon through, the last of the mixture goes on top, and after nearly an hour in the oven and a full cool, a thin white glaze is drizzled over.

How to Make It

  1. Pan lined

    Heat oven to 350°F and line a 9-by-5-inch loaf pan.

  2. Dry mix

    Whisk the flour, baking powder and salt.

  3. Batter

    Beat the softened butter and granulated sugar until fluffy. Beat in the eggs one at a time, then the vanilla and sour cream. Fold in the dry ingredients.

  4. Pecan mixture

    Mix the pecans, brown sugar, cinnamon and melted butter.

  5. Layered and swirled

    Spread half the batter in the pan, add most of the pecan mixture, cover with the remaining batter and swirl lightly. Sprinkle the remaining pecans over the top.

  6. Baked

    Bake 50 to 55 minutes until a tester comes out clean. Cool completely.

  7. Glazed

    Whisk the powdered sugar with the milk and drizzle over the loaf.

Filling the Loaf Pan

Batter, ribbon, batter, topping.

  1. Half the batter

    Spread level in the lined pan.

  2. Pecan mixture

    Most of it scattered over the batter.

  3. Remaining batter

    Spread over, then swirled lightly.

  4. Last of the pecans

    Sprinkled on top before baking.

Glaze only once the loaf has cooled completely.

Ingredient Notes

Sour cream
Half a cup, beaten in after the eggs.
Toasted pecans
Half a cup chopped, mostly for the ribbon, a little for the top.
White glaze
Powdered sugar and milk, drizzled once the loaf is cool.

Why This Recipe Works

  • Sour cream keeps a dense loaf cake moist.
  • Melted butter binds the pecan mixture so it bakes into a ribbon rather than dry crumbs.
  • Swirling lightly keeps a visible marbled line.
  • Pecans on top toast as the loaf bakes.

Success Tips

  • Add the eggs one at a time so the batter stays smooth.
  • Swirl with a knife in two or three strokes only.
  • Tent with foil if the top browns before the centre is done.

Serving Ideas

Cut thick slices to show the pecan ribbon, and serve with coffee.

Storage and Reheating

Refrigerate

Wrap the cooled loaf and keep at room temperature for two or three days.
