Caramel-Like Brown Sugar Glaze

- 1/2 tsp vanilla extract

Step-by-Step Instructions
Step 1: Prep the pan and preheat
Heat the oven to 350°F (175°C) with a rack in the center. Lightly grease a 9×5-inch loaf pan, then line it with a parchment sling (long strip that overhangs the long sides) for easy removal. Grease the parchment, too.
Step 2: Prep the plums
Halve and pit the plums, then dice into 1/2-inch pieces to make 2 cups (about 280 g). In a small bowl, toss the diced plums with 1 tsp cornstarch and 1 tsp lemon juice (if using). Set aside.
Step 3: Mix the dry ingredients
In a large bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, and cloves until evenly combined and no spice clumps remain.
Step 4: Whisk the wet ingredients
In a separate medium bowl, whisk the eggs, brown sugar, oil, yogurt, milk, and vanilla until smooth and glossy.
Step 5: Combine and fold in the plums
Pour the wet mixture into the dry. Use a spatula to fold just until a few dry streaks remain. Add the prepared plums (reserve a tablespoon or two to dot the top if you like) and fold gently until evenly distributed. Do not overmix; a few small lumps are fine.
Step 6: Pan, top, and bake
Scrape the batter into the prepared pan and smooth the top. Sprinkle evenly with the turbinado (or brown) sugar and dot with the reserved plum pieces if desired. Bake for 55–65 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs, and the center registers about 205°F (96°C). If the top is browning too quickly around 40 minutes, tent loosely with foil.
Step 7: Make the brown sugar glaze
Near the end of baking, combine butter, brown sugar, milk, and salt in a small saucepan. Bring to a gentle simmer over medium heat, stirring, and cook for 1 minute. Remove from heat and stir in vanilla. Keep warm.
Step 8: Glaze, cool, and slice
Cool the loaf in the pan for 10 minutes. Use the parchment to lift it out onto a wire rack. Brush the warm glaze over the top (and sides if you like) until it soaks in and leaves a glossy, caramel-like sheen. Cool at least 1 hour before slicing for the cleanest cuts.
Pro Tips
- Weigh your flour for consistent results; too much flour makes quick bread dry. If measuring by cups, fluff, spoon, and level.
- Tossing plums with a touch of cornstarch helps keep their juices from sinking or creating gummy pockets.
- Check doneness early. Every oven runs differently; start checking at 50 minutes.
- If you love a crackly crust, stick with turbinado sugar on top; it keeps its crunch under the glaze.
- Let the loaf cool fully before slicing. The crumb sets as it cools and slices much more neatly.
Variations
- Almond–Plum: Add 1/2 tsp almond extract to the batter and 1/2 cup (50 g) sliced almonds over the sugar topping.
- Cardamom Twist: Replace cloves with 1/2 tsp ground cardamom for a fragrant, slightly floral note.
- Whole-Wheat: Swap 3/4 cup (90 g) of the all-purpose flour for white whole wheat flour; add 1 extra tbsp milk if the batter seems thick.
Storage & Make-Ahead
Store the cooled bread airtight at room temperature for up to 3 days or refrigerate for up to 5 days. For longer storage, wrap whole or sliced loaf tightly in plastic, then foil, and freeze up to 2 months. Thaw wrapped at room temperature. To refresh, warm slices in a 300°F (150°C) oven for 8–10 minutes or briefly toast.
