Step-by-Step Instructions

Step 1: Preheat & Prepare the Pan

Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper for easy removal.

Mix in the egg and vanilla extract until well combined. Then, stir in milk until smooth.

Step 5: Combine Everything

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.

Spread the dough evenly in the prepared pan. Bake for 18-22 minutes until the edges are golden brown.
