Description

Biscoff flapjack magic blends caramelized cookie spread with classic British oat bars. Rich butterscotch notes and crumbled Biscoff cookies create an irresistible sweet treat you cannot resist.


Ingredients

Scale
  • 1 cup (225 grams) unsalted butter
  • ¾ cup (180 grams) Biscoff spread (smooth or crunchy)
  • 3 ½ cups (300 grams) rolled oats
  • ⅓ cup (100 grams) light brown sugar
  • 3 tbsps golden syrup or honey
  • 1 pinch of salt
  • tbsps melted Biscoff (optional topping)

Instructions

  1. Prepare Baking Setup: Preheat oven to 350F (175C) or 160C fan. Line a square baking tin completely with parchment paper, ensuring full base and side coverage.
  2. Create Liquid Base: Melt butter, Biscoff spread, sugar, and golden syrup in a saucepan over low heat. Stir continuously until ingredients merge into a smooth, glossy mixture with uniform consistency.
  3. Combine Flapjack Mixture: Remove saucepan from heat and fold in oats and salt. Ensure thorough coating and even distribution of ingredients throughout the mixture.
  4. Mold and Compress: Transfer mixture into lined baking tin. Use a spatula to press and compact the ingredients, creating an even, dense layer that will transform into a delectable treat.
  5. Bake and Monitor: Slide tin into preheated oven and bake for 20-25 minutes. Watch for golden-brown edges while maintaining a slightly soft center, which indicates perfect texture and doneness.
  6. Cool and Finish: Remove from oven and let flapjack rest in tin for 10 minutes to set. Optional: Drizzle additional melted Biscoff spread across the surface for enhanced flavor. Allow to cool completely at room temperature.
  7. Serve: Once fully cooled, slice into uniform squares or rectangular bars using a sharp knife, revealing the perfectly baked flapjack.

Notes

  • Prevent Burning: Low heat is crucial when melting ingredients to avoid scorching butter or caramelizing sugar too quickly, which could create bitter undertones.
  • Create Consistent Texture: Press mixture firmly and evenly into the baking tin to ensure uniform thickness, guaranteeing balanced baking and a perfect chewy-crisp flapjack texture.
  • Customize Dietary Needs: Substitute dairy butter with coconut oil or vegan butter for a plant-based version, maintaining the recipe’s rich, indulgent flavor profile.
  • Control Sweetness Level: Adjust Biscoff spread quantity based on personal preference – less spread means lighter sweetness, while more creates a more intense caramelized flavor.
