Perfectly Moist Irish Wheaten Bread

Preheat oven to 400 degrees F (200 degrees C).

Prepare a shallow baking pan with cooking spray.

Sift together the bread flour, whole wheat flour, salt, baking soda, and 2 teaspoons sugar in a bowl.

Cut the margarine into the flour mixture until pieces are nearly indistinguishable.

Make a well in the center of the mixture and pour in the oil and buttermilk.

Stir with a spatula until dry mixture is completely moistened.

Move the dough to a lightly-floured surface.

Lightly knead the dough for no more than 1 minute.

Place the dough into the prepared pan; pat down and around to form a round loaf.

Cut a cross into the top of the loaf with your finger.

Brush the top with 1 tablespoon buttermilk; sprinkle 1 teaspoon sugar over the top of the loaf.

Bake in the preheated oven for 30 minutes.

Reduce heat to 375 degrees F (190 degrees C); rotate pan and bake another 30 minutes.

Allow loaf to cool on a wire rack before slicing.
