Instructions
1
Preheat oven to 180°C/gas mark 4. Grease two 8 inch cake tins with dairy-free spread
2
Add the avocado flesh to a food processor, then fold in eggs, vanilla and water. Blend all of the ingredients until creamy
\n
3
Add the sugar, cocoa powder, rice flour, melted chocolate, pecans and chocolate chips. Stir together all of the ingredients, fold in the baking soda and stir until just combined
4
Transfer the mixture to your prepared tins, levelling out the top and spreading the mix out to the edges
5
Sprinkle with sea salt flakes and bake in the oven for 20-25 minutes, or until a toothpick inserted comes out clean
6
Allow to cool completely before removing from the tins and placing on a cooling rack
7
Meanwhile, prepare the buttercream. Mix together the dairy-free spread and icing sugar, gently pour in the coffee and beat the mixture until creamy and smooth. Keep in the fridge until ready to use
8
Spread the buttercream over one of the cakes and place the remaining cake upside-down on top
9
To prepare the glaze, melt the chocolate in a heatproof bowl over a pan of boiling water. Once melted, mix in 1 tbsp of water and allow to cool a little
10
Pour the chocolate glaze over the brownie cake, making sure it's evenly coated on all sides
11
Decorate the edges of the cake with chopped pecans and almonds, making sure you work quickly before the glaze sets
12
Top with halved pecans, allow to set and serve at room temperature or slightly chilled. You can store in the fridge in an airtight container for up to 2 days if not serving immediately. Enjoy!

Tips & Notes
Pro tips
Melt dairy-free chocolate gently over low heat or in a double boiler to prevent seizing; let it cool slightly before folding into the batter.
Measure avocado by weight and ensure it's ripe but not oxidized — browning will discolor the batter. Use immediately after blending.
Fold ingredients gently by hand after mixing the wet base; overmixing develops gluten-like structure in rice flour and can toughen the cake.
Check doneness at 25–30 minutes; this dense cake cooks quickly and is best eaten with a fudgy center rather than fully set.
Substitutions
Rice flour → cornstarch or buckwheat flour (1:1 ratio; cornstarch may slightly reduce chewiness)
Dutch process cocoa powder → natural cocoa powder (reduce water by 1 tbsp; cocoa will taste slightly more acidic)
Demerara sugar → coconut sugar or caster sugar (1:1 ratio; texture and sweetness remain the same)
Storage & make-ahead
Store in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days. Warm gently in a 160°C oven for 5 minutes before serving.
Common Questions
Can I use regular chocolate instead of dairy-free?
No — standard chocolate contains milk. Use certified dairy-free dark chocolate to keep the recipe dairy-free.
Why is avocado used in this brownie cake?
Avocado replaces butter and adds fat and moisture for a tender, fudgy texture while keeping the cake dairy-free.
Can I substitute pecans with another nut?
Yes — walnuts or almonds work equally well as a 1:1 swap.
How do I know when the cake is done?
A toothpick inserted into the center should come out with a few moist crumbs, not wet batter. Overbaking will dry it out.
Can this recipe be scaled up?
Yes — double all ingredients for a larger cake. Increase baking time by 5–10 minutes and check for doneness.
