Whole wheat pain de mie is a soft, fine-crumbed sandwich bread baked in a lidded Pullman pan, which gives the loaf its square slices and thin, tender crust. This version uses three parts whole wheat flour to two parts bread flour, enriched with milk, honey and butter, and is sized for one standard 13x4x4-inch pan.
Two things keep the loaf light instead of heavy. First, the whole wheat flour soaks in the warm liquid for 20 minutes before kneading, so the bran softens and takes up water instead of drying out the dough later. Second, the dough is kept fairly soft and kneaded thoroughly; the bread flour supplies the extra gluten that whole wheat flour lacks.
Timing the final rise matters more than the clock: the lid goes on when the dough is about 1/2 inch below the rim, so the loaf fills the corners without being squeezed into a dense crumb. For another soft wheat loaf, see the old-fashioned whole wheat potato bread.

Ingredients
Method
- Warm the 1 cup milk and 2/3 cup water together until just warm to the touch, 100 to 110°F. Pour into a large bowl or the bowl of a stand mixer and stir in the 3 tablespoons honey and the yeast.
- Stir in the 3 cups whole wheat flour until no dry spots remain. Cover the bowl and let the mixture rest for 20 minutes so the bran can absorb liquid.
- Add the 2 cups bread flour, the 4 tablespoons soft butter and the 2 teaspoons salt. Mix until a shaggy dough forms.
- Knead until the dough is smooth, elastic and only slightly tacky: 7 to 8 minutes with a dough hook on medium-low speed, or 10 to 12 minutes by hand on a lightly floured surface. If the dough feels stiff, work in 1 to 2 tablespoons of water; if it sticks heavily, dust with a little bread flour. Keep it on the soft side.
- Shape the dough into a ball, put it in a lightly greased bowl, cover, and let it rise in a warm place until doubled, 60 to 90 minutes.
- Generously butter a 13x4x4-inch Pullman (pain de mie) pan and the underside of its lid.
- Press the risen dough down to deflate it. On a lightly floured surface, pat it into a rectangle about 13 inches long and 8 inches wide. Roll it up tightly from a long side, pinch the seam closed, and set the log seam side down in the pan. Press it gently so it reaches the ends and lies level.
- Slide the lid on most of the way, leaving a gap to look through, or cover the pan with plastic wrap. Let the dough rise until its top is about 1/2 inch below the rim of the pan, 45 to 60 minutes. Toward the end of the rise, heat the oven to 350°F.
- Close the lid completely. Bake for 25 minutes.
- Carefully slide off the lid and bake for 15 to 20 minutes more, until the top is golden brown and an instant-read thermometer in the center reads 190 to 195°F.
- Turn the loaf out of the pan right away and cool it completely on a wire rack, at least 2 hours, before slicing.
