Oat Bars With Raspberry Jam Recipe

Last Update: November 4, 2025

These oat bars feel like cozy dessert meets comfort snack—rich, nutty, sweet and just the right kind of indulgent. The recipe calls for chopped pecans, walnuts and almonds toasted until golden, combined with nut flour, rolled oats, dark brown sugar and monkfruit sweetener, then layered with a ribbon of raspberry jam and baked until the top and edges are slightly crisp.

When served warm, the bars hit the sweet-spot between a cookie and a crumble: the oat-nut crust gives texture, the jam adds a glossy tart onset, and the warm bars bring that freshly baked-dessert feel—ideal for those afternoons when you want something special yet simple. Because the core ingredients skip wheat flour and rely on nut flour, this recipe naturally aligns with gluten-free baking (assuming all components are certified gluten-free) and vegetarian diets.

Bake them for an hour in an 8×8-inch pan, let them cool slightly so they hold shape, then slice into squares. Serve warm with a scoop of dairy-free vanilla ice cream or a dollop of Greek-style yogurt if you’re keeping it lighter. They’re perfect for treating yourself, sharing with friends, or wrapping up as a thoughtful homemade gift.

How to Make Oat Bars

  1. Preheat oven to 350 degrees. Spray an 8-inch square baking pan with non-stick spray and line with parchment paper.
  2. Place mixed nuts on baking sheet and roast in oven 5 to 7 minutes, until a light golden brown. Let cool and then coarsely chop.
  3. In a large bowl, whisk the nut flour with the rolled oats, monkfruit sweetener, brown sugar, salt, baking soda, and toasted nuts. Stir in the melted butter until the oat mixture is thoroughly combined.
  4. Press two-thirds of the oat mixture in an even layer on the bottom of the prepared baking pan and top with raspberry jam.
  5. Sprinkle the jam with the remaining oat mixture. Bake bars for 35 to 45 minutes, rotating the pan halfway through baking.
  6. Let cool completely before cutting into squares.

Oat Bar Variations & Tips

  • Nut-free crust variation: Replace the chopped pecans, walnuts and almonds with ground pumpkin seeds or sunflower seeds for a nut-free version.
  • Jam substitution: Use apricot, strawberry or mixed berry jam in place of raspberry for a different flavor ribbon.
  • Sweetener tweak: If you prefer less sweetness, reduce the dark brown sugar by 2 tablespoons or use a lower-glycemic sweetener alternative.
  • Texture tweak: For more chew, increase the rolled oats by ¼ cup; for crisper bars, spread the mixture slightly thinner in the pan before baking.
  • Warm serving tip: Slightly rewarm slices in a 300 °F oven for 5 minutes before serving — the jam ribbon becomes soft again and the edges crisp up.

Best Oat Bar Pairings

  • Dairy-free vanilla ice cream: A cold buttery scoop balances the warm bars and adds a creamy contrast.
  • Greek-style yogurt with honey drizzle: Adds tang and lightness if you’re serving for brunch or breakfast-style treat.
  • Fresh raspberries or berries on the side: Echo the jam flavor while bringing freshness and color.
  • Hot herbal tea or coffee: A warm beverage complements the baked-in-oven warmth of the bars and rounds out the dessert experience.
  • Almond milk latte or oat milk cappuccino: Match the nut base of the bars with a nut-milky drink for a harmonized pairing.

When to Make Oat Bars

  • Afternoon snack time: Warm these bars after school or mid-day when you want something more special than a standard cookie.
  • Brunch dessert option: Serve alongside fruit and yogurt for a casual weekend brunch treat.
  • Homemade gift idea: Slice and wrap squares in parchment with ribbon for a thoughtful homemade gift for friends or neighbors.
  • Cozy evenings dessert: Serve warm straight from the oven at family gatherings or while watching a movie.
  • Gluten-free friendly baking: These bars are a welcome option when you’re preparing treats for guests with gluten-free dietary needs.
