Irish brown soda bread

Cut about a quarter stick of cold butter into small cubes.

Mix the dry ingredients (all-purpose and whole wheat flour, sugar, baking powder, baking soda, salt) in a bowl and add the cold butter.

Preheat the oven to 375F and line a cast iron skillet with parchment.

Cut the butter into the dry mixture with a pastry cutter, then check with the hands for any missed pieces.

Stir about a quarter cup of molasses into the buttermilk and add it to the dry ingredients.

Work it together with a spatula, then by hand, until it feels a little tacky but not wet.

Set it in the skillet, flatten it a bit and cut a deep cross.

Brush the top with a little more buttermilk and sprinkle with oats.

Bake at 375F for 45 minutes or so, until deep golden brown and hollow-sounding when tapped; cool a bit.
