Small-Batch Birthday Cake Blondies

Step 1: Preheat the oven to 350°F with a rack in the center. Lightly grease a 9-inch by 5-inch loaf pan. Line the pan with a parchment sling and lightly grease the parchment.

Step 2: In a medium bowl, use a flexible spatula to combine the sugars, vanilla, salt, and almond flavoring.

Step 3: In a small saucepan over medium heat or in a microwave-safe bowl, melt the butter, then pour it directly over the sugar mixture while it's still hot.

Step 4: Stir gently with the spatula to combine, then mix vigorously for 20 seconds. The mixture will become thicker and slightly lighten in color.

Step 5: Add the egg and continue stirring until combined, then mix in the flour and baking powder until a few dry streaks of flour remain. Add about 2 teaspoons of the sprinkles, then continue mixing until fully incorporated.

Step 6: Transfer the batter to the prepared pan and spread it evenly to the edges. Sprinkle the remaining 1 teaspoon of sprinkles over the top of the batter.

Step 7: Bake the blondies for 24 to 28 minutes, until the center is set, the top is brown, and a toothpick or thin knife inserted into the center comes out with a few moist crumbs. The toothpick does not need to come out clean, but there should be no raw batter.

Step 8: Remove the blondies from the oven and cool completely in the pan on a rack. Use the parchment to lift the blondies out of the pan and transfer them to a cutting board before slicing and serving.

Step 9: Store leftover blondies in an airtight container at room temperature for several days, or freeze them for longer storage.
