Traditional Irish Brown Loaf

Preheat your oven to 375 degrees Fahrenheit, which is equivalent to 190 degrees Celsius. To prevent the baking sheet from sticking, lightly coat it with a thin layer of oil or cooking spray.

In a large mixing bowl, combine 2 cups of all-purpose flour, 1 cup of granulated sugar, 2 teaspoons of baking powder, 1 teaspoon of baking soda, and a pinch of salt. Use a pastry blender or your fingers to break down the butter into small pieces and mix it with the flour until you achieve a crumbly texture. Add 1/2 cup of whole wheat flour and 1/4 cup of quick-cooking oatmeal, stirring until everything is well combined.

Next, add 1 cup of yogurt to the mixture and gently stir until it's fully incorporated. If the dough starts to feel too dry, you can add a little milk at a time until it reaches your desired consistency. Be careful not to overdo it, as you want the dough to hold together without being too sticky.

Turn the dough out onto a lightly floured surface and use your hands to knead it gently about 5 times, until it forms a cohesive ball. Place the dough in the center of your prepared baking sheet and use a sharp knife to cut an 'X' shape on top of the loaf.

Bake the bread in your preheated oven for about 40 minutes, or until it's nicely browned. Remove the bread from the oven and transfer it to a wire rack to cool completely. You can serve your warm or cold bread, whichever you prefer.
