Soft, gooey blondies with rich nutty browned butter, sweet spiced apple butter, fresh apples, and topped with a creamy cinnamon maple glaze. A cozy fall treat bursting with warm spices and comforting flavors.
Use salted butter to balance sweetness; if using unsalted, add a pinch of salt to batter or glaze., Do not overmix the batter after adding flour to avoid tough blondies., Choose crisp apples like Honeycrisp, Fuji, or Gala; peeling is optional., Swirl any apple juice pooling on top into batter and bake extra to prevent sogginess., For neater cuts, chill bars 15-30 minutes or dip knife in hot water and dry between cuts., Chilling bars 10-15 minutes before glazing helps set the glaze quickly., Mix-ins like chopped toasted nuts or chocolate chips can be added according to preference., Make ahead by baking and storing unglazed; add glaze before serving., Store covered at room temperature for 3-4 days or refrigerated 5-6 days; freeze unglazed bars for up to 3 months., Glaze is optional; bars are delicious without it.
