Estimated values based on one serving size.


  1. Generously grease a 10 inch heart shaped baking pan with butter and coat in flour. Shake out excess and set aside.
  2. In a large saucepan, melt butter over medium heat for 5-7 minutes or until browned, remove from heat. Working in the saucepan add sugars and whisk until combined. Quickly whisk in eggs, one at a time to prevent scrambling. Add vanilla, lemon juice, flours and salt and whisk again until smooth. Pour into the prepared heart-shaped pan, set aside.
  3. To a medium bowl add jam, maple syrup and food colouring, mix. Reserve ½ cup of mixture for later. Add 2 tbsp of blondie batter to the original medium bowl and mix until combined.
  4. Dollop rhubarb and batter mixture in a random pattern on top of the blondie in the heart-shaped pan. Use a butter knife to swirl in a decorative pattern vertically and horizontally, keeping your knife on the surface of the blondie. Bake at 350F for 25-30 minutes until golden brown.
  5. Serve blondie with ice cream and drizzle over extra Rhubarb ripple if desired, enjoy!
