Method
Reduce the apple cider
- Bring apple cider to a simmer over medium heat until reduced to 1/4 cup, then cool completely.
Prep the oven and pan
- Preheat the oven to 350F and grease an 8x8 square baking pan.
Mix the dry ingredients
- Whisk together all-purpose flour, baking powder, cinnamon, nutmeg, allspice, and salt.
Mix the wet ingredients
- Whisk melted unsalted butter, granulated sugar, eggs, vanilla extract, reduced cider, and sour cream until smooth.
Combine batter
- Fold the flour mixture into the wet ingredients just until combined, then pour the batter into the prepared pan.
Bake
- Bake for 25-30 minutes at 350F until a toothpick inserted in the center comes out clean.
Butter and coat
- While warm, brush the top generously with melted unsalted butter.
- Mix cinnamon and sugar together, then shower evenly over the buttered cake.
Slice and serve
- Cut into squares and serve.
Notes
For the cleanest crumb, fold the flour in only until no dry streaks remain, then bake promptly. Store covered at room temperature for up to 2 days or refrigerate for up to 5 days; freeze cooled squares for up to 2 months. If you want a lighter option, swap sour cream with plain low-fat Greek yogurt for a similar tang and moisture.
