How to Make Icelandic Happy Marriage Cake

  1. Preheat oven to 400°F (200°C).
  2. Grease a 9-inch square baking pan.
  3. In a large bowl, combine 1 ½ cups rolled oats, 1 cup all-purpose flour, ¾ cup packed brown sugar, ½ cup granulated sugar, and 1 teaspoon baking soda.
  4. Cut in 1 cup (2 sticks) cold unsalted butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  5. Beat in 1 large egg and 1 teaspoon vanilla extract until just combined.
  6. Press two-thirds of the dough into the bottom of the prepared pan.
  7. Spread 1 cup rhubarb jam evenly over the dough layer.
  8. Crumble the remaining dough evenly over the jam layer.
  9. Bake for 20-25 minutes, or until the topping is golden brown and the crust is set.
  10. Let cool completely in the pan before slicing and serving. For best flavor, let it sit for at least a few hours, or even overnight!
