Fudgy Flourless No-Sugar-Added Brownies
You know those days when only the deepest, darkest chocolate will do? When the situation calls for something properly fudgy and rich, and nothing else is going to cut it? These brownies make their grand entrance exactly when needed.
The crackly top is real. The fudgy centre is real. The dense, satisfying chew that makes a brownie worth making is also very much real. What is not real is the 28g of added sugar that usually comes with it.
Allulose is the entire reason these work. It creates the crackle, keeps the centre moist, and doesn't leave you with the hollow cooling sensation that other sweeteners produce. Chill them for an hour before serving and they reach their full potential.

Ingredients
Serves 16 squares · Scale as needed
- 150g (1½ cups) ⇄ almond flour — the flour swap ⇄ the swap
- 45g (½ cup) unsweetened cocoa powder
- 150g (¾ cup) ⇄ allulose — the sweetener swap ⇄ the swap
- ½ tsp baking powder
- ¼ tsp sea salt
- 3 large eggs
- 115g (½ cup) unsalted butter, melted
- 1 tsp vanilla extract
Instructions
- 1
Preheat your oven to 175°C (350°F) and line an 8x8 inch baking pan with parchment paper.
- 2
In a large bowl, sift together the almond flour, cocoa powder, allulose, baking powder, and salt.
- 3
In a separate bowl, whisk the eggs with the melted butter and vanilla until smooth.
- 4
Pour the wet ingredients into the dry and stir until a thick, glossy batter forms.
⇄ Swap NoteAllulose is essential here — it creates the crackly top and keeps the centre fudgy without the cooling effect of erythritol.
- 5
Spread the batter evenly into the prepared pan, smoothing the top with a spatula.
- 6
Bake for 18–22 minutes. Do not overbake — a toothpick should come out with moist crumbs, not clean.
- 7
Allow to cool completely in the pan before slicing into 16 squares.
- 8
For the best fudgy texture, refrigerate for 1 hour before serving.
Why I Made This Swap
A standard brownie contains around 28g of added sugar per square — most of it refined white sugar that delivers a quick spike followed by the characteristic afternoon slump. Allulose is specifically good in brownies because it creates the same caramelisation and moisture retention as regular sugar, producing that crackly top and dense interior without contributing to blood sugar in the same way.
Common Mistakes
- Overbaking. This is the most common brownie mistake. They look underdone when they come out. They're not. Trust the timer.
- Cutting while warm. Warm almond flour brownies fall apart. Cool completely, then refrigerate. Then slice.
- Using cocoa that has been sitting in the cupboard for two years. Old cocoa tastes flat. Good, fresh cocoa powder makes a significant difference in a recipe this simple.
Storage
Store in an airtight container in the fridge for up to 1 week. Freeze individual squares for up to 2 months — they defrost at room temperature in about 20 minutes.

Frequently Asked Questions
Can I add chocolate chips?
Yes — fold in 60g of sugar-free dark chocolate chips with the batter. Allulose-sweetened chips keep it completely sugar-free.
Can I use coconut oil instead of butter?
Yes, same quantity. The texture will be slightly different but still good.
Why is allulose better than monk fruit here?
Monk fruit doesn't caramelise or create the crackly top effect. Allulose behaves like sugar in the oven, which is exactly what gives these brownies their character.
