Let’s get baking! Here’s a detailed, step-by-step guide:

Step 1: Preheat Oven and Prepare Baking Sheet

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Step 2: Combine Dry Ingredients

In a large bowl, whisk together the self-rising flour and baking soda.

Step 3: Cut in Butter

Add the very cold, cubed butter to the flour mixture.

Using a pastry blender (or two knives), cut the butter into the flour until the mixture resembles coarse crumbs. You want the butter to be in small, pea-sized pieces. It’s important to work quickly and keep the butter cold.

Step 4: Add Buttermilk

Make a well in the center of the flour and butter mixture.

Pour in the buttermilk.

Stir with a fork just until the mixture starts to come together to form a shaggy dough. Don’t overmix.

Step 5: Fold and Roll Dough (First Time)

Transfer the dough to a lightly floured work surface.

Press the dough into a roughly shaped rectangle.

Fold the dough into thirds (like a letter) using a bench scraper (or your hands).

Press the dough again into a rectangle. Lightly flour the surface if the dough seems sticky.

Roll the dough with a rolling pin to about 1/2-inch thickness.

Step 6: Add Cheese and Onions (First Layer)

Sprinkle the dough with 1/4 cup of the shredded Irish Cheddar cheese and 1/8 cup of the sliced green onions.

Step 7: Fold and Roll Dough (Second Time)

Fold the dough into thirds again.

Dust with flour if necessary, and roll out again to about 1/2-inch thickness.

Step 8: Add Cheese and Onions (Second Layer)

Top the dough with the remaining 1/4 cup of cheese and 1/8 cup of green onions.

Step 9: Fold and Roll Dough (Third Time)

Fold the dough into thirds one last time.

Roll out the dough again to about 1/2-inch thickness.

Step 10: Cut Out Biscuits

Use a 2- or 3-inch round cutter to cut out the biscuits. Press straight down and don’t twist the cutter, as this can seal the edges and prevent the biscuits from rising properly.

Step 11: Prepare for Baking

Transfer the biscuits to the prepared baking sheet, placing them close together (they can touch).

Brush the tops of the biscuits lightly with additional buttermilk.

Sprinkle the tops with a little extra shredded cheese (about 1 teaspoon per biscuit).

Step 12: Bake

Bake in the preheated oven for about 20 minutes, or until the biscuits are cooked through and golden brown.

Step 13: Cool and Serve

Transfer the baked biscuits to a wire rack to cool slightly.

Serve warm, with butter, jam, honey, or your favorite toppings.
