  • Pulse until combined.
  • Add butter, a little at a time, pulsing after each addition.
  • Continue to pulse until the mixture looks like cookie crumbs.
  • Place 2/3 of mixture in bottom of prepared pan.
  • Spread evenly and press down firmly.
  • Bake for 15 to 18 minutes until just starting to brown.
  • Remove from oven and spread top with jam.
  • Sprinkle the remaining 1/3 of crust mixture evenly over the top of the raspberry jam.
  • Return to oven and bake for about 40 minutes, until set and light golden brown.


  • If you use vegan butter, this recipe will be a delicious vegan treat!
  • You can use your favorite store-bought raspberry jam.
  • You could also use any other flavored jam that you like! Strawberry, blackberry, blueberry, etc.
Expert Tips:
  • Keep the layers thin! The thicker the layers of crumble and jam, the longer it'll take to cook.
  • Try and get the base layer as even as you can. Use your hand or anything flat to press the crumble down.
  • This recipe keeps really well!
