Equipment
Method
Step 1: Preheat & Prepare Pan
- Preheat your oven to 350°F (175°C).
- Line an 8x8 baking pan with parchment or grease well.
Step 2: Mix Wet Ingredients
- In a medium mixing bowl, add melted butter and brown sugar. Stir until smooth.
- Add the egg and vanilla extract. Mix until fully incorporated.
🥄 No electric mixer needed — just a whisk or spoon and a little elbow grease!
Step 3: Add Dry Ingredients
- Add flour, cinnamon, and a pinch of salt.
- Stir until a thick batter forms. Don’t overmix.
Step 4: Pour & Sprinkle
- Pour batter into prepared pan and smooth the top.
- Sprinkle the 5 teaspoons of sugar evenly across the surface. This gives a sweet, sparkly crust.
Step 5: Bake
- Bake for 22–25 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
- Let cool for at least 10 minutes before slicing into squares.
🍂 Your kitchen will smell like brown sugar and cinnamon heaven.
