Ingredients

  • 1 ½ cups all-purpose flour
  • 1 ½ cups old-fashioned rolled oats
  • ¾ cup brown sugar packed
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ¾ cup unsalted butter melted
  • 1 teaspoon vanilla extract
  • ¾ cup jam or preserves, strawberry, raspberry, apricot, your choice

Instructions

  • Preheat to 350°F (175°C). Line an 8×8-inch pan with parchment paper or grease well.
  • In a large bowl, mix flour, oats, brown sugar, baking soda, salt, and cinnamon (if using). Stir in melted butter and vanilla until a crumbly dough forms.

  • Press ⅔ of the oat mixture firmly into the bottom of the pan. Spread jam evenly over the top, leaving a little space around the edges. Crumble the remaining oat mixture on top.

  • Bake for 30–35 minutes, or until golden brown on top and bubbly around the edges. Let cool completely before slicing (seriously, it's worth the wait).

Notes

  1. Jam type: Use thick, high-quality jam or preserves, runny jam can leak and burn around the edges.
  2. Oats: Rolled oats give you that hearty texture; quick oats make the bars softer and less defined.
  3. Add-ins: Toss in a handful of chopped nuts or shredded coconut to the topping if you like.
  4. Slicing tip: Let them cool completely for clean cuts, warm bars = crumble city.
  5. Make ahead: These bars actually get better the next day. The flavors settle and the oat base firms up.
