Ingredients

• 3 cups Old-fashioned oats (bulk ingredient; use as base for bars.)
• 2 cups All-purpose flour (bulk ingredient; helps structure.)
• 1.5 cups Brown sugar, packed (tenderizes bars; adjust to sweetness.)
• 1 cup Unsalted butter, melted (room temp to melt evenly; BoxNCase uses standard bulk packs.)
• 2 large Eggs (binder for bars.)
• 1/2 cup Robertson's Silver Shred Marmalade (BoxNCase product: Robertson's Silver Shred Marmalade 16.0oz (454g). Adds citrus warmth to swirl.)
• 1/2 cup Robertson's Golden Shredless Marmalade (BoxNCase product: Robertson's Golden Shredless Marmalade 16.0oz (454g). Swirl for bright bites.)
• 1 tsp Vanilla extract
• 1/2 tsp Baking powder
• 1/4 cup Golden Syrup (BoxNCase product: Tate & Lyle's Golden Syrup Tin 16oz (454g). Drizzle after bake for gloss and extra sweetness.)

Instructions

1. Preheat oven to 350°F (175°C). Line a 9x13-inch sheet pan with parchment.
2. Whisk oats, flour, baking powder, and salt (if using) in a large bowl.
3. Stir melted butter, brown sugar, eggs, and vanilla in another bowl until glossy. Fold into dry ingredients until just combined.
4. Spoon two-thirds of the batter into the pan and press to an even layer.
5. Warm marmalades slightly to loosen. Dollop half over batter, then swirl gently with a knife. Repeat with remaining marmalade, layering and swirling to create a marbled effect.
6. Spread remaining batter over the top to seal the swirl. Bake 22-28 minutes until edges are golden and center is set. (26 min)
7. Cool completely in pan. Drizzle with Golden Syrup before cutting into 2x2-inch bars.
8. Cut into 48 bars and store in airtight containers for up to 1 week at room temperature or freeze for longer.
