An oat slice recipe is one of these Australian classic recipes that kids love to eat in New Zealand for a snack. It’s not as soft as my peanut butter banana oatmeal bars. It’s crunchier with a slightly crumbly texture, similar to cookies. Like oatmeal cookies, it’s made with rolled oats and flour.

Instrucciones para la impresión en alta definición
- Preheat the oven to 350°F (180°C). Line an 8-inch x 8-inch slice pan (20cm x 20cm) or pan with parchment paper. Slightly oil the paper with coconut oil. Set it aside.
- In a large bowl, whisk dry ingredients: flour, rolled oats, baking powder, desiccated coconut, and soft brown sugar.
- Stir in almond milk, melted margarine, maple syrup, and vanilla extract.
- Stir the liquid ingredients into the dry ingredients and fold in sultanas just before the end.
- Transfer the batter to the prepared pan and sprinkle chocolate chips on top.
- Bake in the center rack of the oven for 25 to 30 minutes, until golden brown, and a pick inserted in the center comes out with just a few crumbs on it. Don't over bake or they get very dry and crumbly.
- Cool down on a wire rack then slice into 16 squares.

Ingredientes
It’s pretty easy to make oat slices, and you can play with flavor by adding some delicious seeds, dried fruits, or chocolate chips to the batter.
Let me share with you how I make them
- Copos de avena tradicionales – this is the coarse version of oats, also called jumbo oats in New Zealand. Don’t use quick oats, or the texture won’t be as good.
- Harina para todo uso – You can also use half oat bran or oat flour and half all-purpose flour. To make this recipe gluten-free, use my Guía de conversión a una dieta sin gluten and pick a gluten-free certified oats brand. In New Zealand, the label gluten-free certified doesn’t exist on oats brands. Check for wheat-free instead.
- Levadura en polvo – To give them a nice airy texture.
- Canela – For added flavors.
- Azucar morena – Or coconut sugar. To make this recipe low-sugar, you can use sugar-free brown erythritol in this recipe from brands like Mother Earth. You can also replace the dried fruits with chopped nuts or seeds.
- margarina – We use dairy-free butter. Brands like Naturli Vegan Block or Nuttelex work well.
- Extracto de vainilla – For the perfect taste and flavor.
- Jarabe de arce or any liquid sweetener you like, such as coconut nectar or agave syrup. This adds a chewy texture to the bars. Honey is not vegan, so we don’t use this in our recipe, but it works if you prefer this option.
- Sultanas – or any dry raisins.
