Ingredients

  • Raisin & Baking Soda Mixture Secret Moisture Step
  • 1 cup 150 g golden raisins (or regular raisins)
  • cups 360 ml water
  • 1 tsp baking soda
  • Wet Ingredients
  • ½ cup 115 g unsalted butter, softened
  • 1 cup 200 g granulated sugar
  • ¼ cup 60 ml vegetable oil (or neutral oil)
  • 2 large eggs room temperature
  • tsp vanilla extract
  • Dry Ingredients
  • 2 cups 250 g all‑purpose flour, spooned and leveled
  • tsp ground cinnamon
  • ¼ tsp ground cloves
  • ½ tsp kosher salt
  • Fresh Carrots
  • –2 cups 150–200 g fresh carrots, freshly grated (about 3–4 medium carrots)
  • Crumb Topping
  • ¾ cup 85 g chopped pecans (or walnuts; omit for nut‑free)
  • ½ cup 100 g dark brown sugar, packed
  • ½ cup 85 g semi‑sweet chocolate chips (or white chocolate / butterscotch chips)

Instructions

  • Boil the Raisins (Moisture Secret)
  • In a small saucepan, combine raisins and water; bring to a gentle boil over medium heat.
  • Stir in baking soda (it will foam — this is normal).
  • Remove from heat; let cool to lukewarm. Do not drain — you will use the liquid too.
  • Preheat and Prep
  • Preheat oven to 350°F (175°C).
  • Grease and lightly flour a 9×13‑inch (23×33 cm) baking pan.
  • Cream Butter and Sugar
  • In a large bowl, beat softened butter and granulated sugar together until light and fluffy, about 2–3 minutes.
  • Add vegetable oil and mix until combined.
  • Add Wet Ingredients
  • Add eggs one at a time, mixing well after each.
  • Stir in vanilla extract.
  • Fold in the raisin mixture (raisins + liquid) until combined.
  • Add Dry Ingredients
  • Stir in flour, cinnamon, cloves, and salt until just combined — do not overmix.
  • Gently fold in freshly grated carrots.
  • Pour Batter and Add Topping
  • Pour batter evenly into prepared pan; smooth with a spatula.
  • In a small bowl, mix chopped pecans, brown sugar, and chocolate chips.
  • Sprinkle crumb topping evenly over the batter.
  • Bake
  • Bake 35–40 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  • Note: a melted chocolate chip on the toothpick is not unbaked batter — check the actual crumb.
  • If the topping browns too quickly, tent loosely with foil after 25 minutes.
  • Cool and Serve
  • Let cake cool completely in the pan on a wire rack before covering or slicing.
  • Cut into squares and serve directly from the pan.

Notes

Secret to moistness: The boiled raisin and baking soda method plumps the raisins, adds liquid to the batter, and creates a caramel‑like depth of flavor — don't skip it.
Grate carrots fresh: Always grate your own carrots just before using for maximum moisture and sweetness; packaged pre‑shredded carrots are too dry.
Don't overmix: Once you add flour, mix only until just combined to keep the crumb tender.
Optional buttermilk glaze: Whisk ½ cup powdered sugar with 2–3 tbsp buttermilk until smooth; drizzle over cooled cake instead of (or alongside) the crumb topping. Let set before packing.
