A soft and chewy Oat Slice that takes just minutes to make.


  • 140 grams (1 cup) plain flour or all purpose flour
  • 100 grams (1 cup) whole rolled oats
  • 60 grams (1/2 cup) shredded coconut
  • 135 grams (3/4 cup) brown sugar
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 115 grams (1/2 cup or 1 stick) unsalted butter, melted
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup mix-in’s of your choice (see notes)


  1. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line an 8-inch square pan with baking or parchment paper, ensuring two sides overhang (this will make it easier to remove the slice later).
  2. In a large mixing bowl, add flour, oats, coconut, brown sugar, baking powder and salt. Give it a quick stir.
  3. In a small bowl, add melted butter, egg and vanilla. Beat briefly with a fork, just to break up the egg yolk.
  4. Add butter mixture to dry ingredients and stir using a spatula until combined. Stir through your mix-in’s.
  5. Transfer mixture to your prepared pan. Use the back of a spoon to press down firmly to form one even layer.
  6. Bake for approximately 25 minutes or until golden. Leave to cool for 15 minutes, then carefully remove from baking pan and set on a wire rack to cool completely.
  7. Cut into small squares to serve. Store leftovers in an airtight container at room temperature.


Coconut: You can use shredded coconut or desiccated coconut for this recipe. Be sure to use unsweetened coconut. If you want to omit the coconut, add an extra 35 grams (1/4 cup) plain flour or all purpose flour.

Mix-in’s: This recipe is highly customisable. I recommend adding 1 cup (total) mix-in’s, but you can choose to add two different mix-in’s (1/2 cup each). The slice pictured has 1/2 cup of chocolate chips and 1/2 chopped pecans. Great options include: chocolate chips, sultanas or raisins, dried cranberries or apricots, almonds, walnuts or macadamias, or even M&M’s.

Storage: Keep slice in an airtight container at room temperature. Or you can freeze the slice.
