Method
Make the blondies
- Heat the oven to 350°F.
- Grease an 8x8-inch metal baking pan and line it with parchment paper, leaving overhang on two sides.
- Whisk the melted butter and brown sugar in a large bowl until combined.
- Whisk in the egg and vanilla.
- In a medium bowl, whisk the flour, baking powder, cinnamon, and salt.
- Fold the dry mixture into the butter mixture just until no dry streaks remain.
- Fold in the apple.
- Spread the batter evenly in the pan.
- Bake for 30–36 minutes, until the edges are golden and set and a toothpick inserted in a spot without apple comes out with a few moist crumbs.
- Cool completely in the pan on a wire rack, about 1 1/2–2 hours.
Make the frosting
- Beat the cream cheese and softened butter in a medium bowl with an electric mixer on medium speed until smooth, about 1 minute.
- Add the powdered sugar, maple syrup, vanilla, and salt.
- Beat on low until incorporated, then on medium until fluffy, about 1 minute.
- Spread the frosting over the cooled blondies.
- Cut into 16 pieces.
Notes
For clean cuts, frost the blondies only after they have cooled completely. Store covered in the refrigerator for up to 5 days; freezing is suitable for up to 2 months. For a gluten-free variation, use a cup-for-cup gluten-free flour blend.
