Jammy Oat Blondies

Recipe: Camilla Wynne

Oat and white rice flours lend a pleasant texture to these rich blondies that are punctuated by tangy jam and topped with streusel. The xanthan gum isn’t necessary but helps give gluten-free treats better texture (or you can substitute all-purpose flour in a pinch).



  • ⅓ cup oat flour
  • 3 tbsp rolled oats
  • 2½ tbsp packed brown sugar
  • ⅛ tsp salt
    2½ tbsp cold unsalted butter, cubed


  • 1¼ cups packed brown sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • ¾ cup unsalted butter, melted
  • 1 cup oat flour
  • ¾ cup white rice flour
  • 1 tsp baking powder
  • 1 tsp salt
  • ¾ tsp xanthan gum (optional)
  • ½ cup jam


Yield: Makes 16 blondies

Make Blondies

  1. Preheat oven to 350°F. Grease 8″-sq. pan and line with parchment paper.
  2. In bowl of stand mixer fitted with whisk attachment, whip brown sugar, eggs and vanilla on high speed, until pale, fluffy and doubled in volume. With mixer running on low, slowly stream in butter until incorporated.
