Healthy Ingredients in the Chocolate Slice
Oat Flour – Oat flour is simply blended rolled oats and is naturally rich in fibre, complex carbohydrates, vitamins, minerals, and antioxidants. Oats contain beta-glucan fibre, which may help support heart health and keep you feeling fuller for longer. Note: Rolled oats are naturally gluten-free; however, they may be processed in facilities that handle gluten-containing grains, so use certified gluten-free oats if required.
Spelt Flour – Spelt flour is an ancient grain related to wheat that provides fibre, vitamins, and minerals. It has a slightly nutty flavour and works beautifully in baked goods, creating a soft texture in this chocolate slice.
Cacao Powder – Cacao powder gives this slice its rich chocolate flavour while also providing antioxidants, magnesium, fibre, and essential minerals. Because cacao powder is less processed than cocoa powder, it retains more nutrients.
Coconut Sugar – Coconut sugar is a less refined alternative to regular sugar and contains small amounts of minerals like iron, potassium, calcium, and zinc. It adds a rich caramel-like sweetness to the slice.
Maple Syrup – Pure maple syrup is a natural sweetener made from maple tree sap. It adds sweetness while also providing antioxidants and minerals such as manganese and zinc. Always use pure maple syrup rather than maple-flavoured syrup.
Coconut Oil – Unrefined coconut oil adds healthy fats and helps create a soft, moist texture in both the base and icing. It also helps the slice firm up once refrigerated.
Desiccated Coconut – Desiccated coconut adds texture and natural sweetness while also providing dietary fibre and minerals including manganese, copper, and selenium.
How to Make Healthy Chocolate Slice
Preheat the oven to 180°C/350°F and line a baking dish with baking paper.
In a large mixing bowl, combine the oat flour, spelt flour, desiccated coconut, coconut sugar, and cacao powder.
Add the melted coconut oil and hot water, mixing until a slightly sticky mixture forms.
Press the mixture firmly into the prepared baking dish and bake for 10–12 minutes, being careful not to overbake.
While the base is baking, prepare the chocolate icing by mixing together the cacao powder, maple syrup, and melted coconut oil until smooth and glossy.
Pour the icing over the warm slice base and spread evenly using the back of a spoon.
Sprinkle with extra desiccated coconut if desired and allow the slice to cool completely before refrigerating.
Refrigerate for at least 2 hours before slicing for the best texture.
Ingredient Substitutions for Chocolate Slice
Plain (all-purpose) flour – Can replace spelt flour 1:1 for a more traditional bake. Gives a softer, lighter texture.
Wholemeal flour – Can replace spelt flour 1:1 for a more traditional, higher-fibre option. Creates a denser texture and may need a little extra water if dry.
Cocoa powder – Can be used instead of cacao powder (less nutrient-dense but works well).
Honey – Can replace maple syrup if not vegan. Brown rice malt syrup also works.
Butter or ghee – Can replace coconut oil in a 1:1 ratio if not vegan.
Coconut flakes – Can replace desiccated coconut for a chunkier texture.
Tips for Making the Best Chocolate Slice
The base mixture should be slightly sticky when pressed together.
If the mixture feels too dry or crumbly, add an extra tablespoon of hot water at a time until it comes together.
Do not overbake the base or the slice may become dry and crumbly.
Line the baking dish with baking paper for easier removal.
Refrigerating the slice before cutting helps it hold together better.
A smaller baking dish will create a thicker slice.
Store the slice in an airtight container in the fridge for up to 7 days.
