Mummy brownies aren’t just a recipe; they’re a little ritual rooted in childhood chaos. I love how the crispy top gives way to gooey, rich chocolate beneath, like a secret waiting to be uncovered. It’s weird how a simple bake can evoke so much nostalgia, especially in times when comfort is needed most. Baking these feels like a small rebellion against the plain, predictable desserts.
Why I Keep Coming Back to These Brownies
They’re imperfectly perfect—crackly top, gooey center, a bit chaotic. Baking them reminds me of childhood kitchens, where everything was about messy love and sweet chaos. They’re quick to whip up, forgiving, and always a hit when I need a little spoonful of comfort.
Breaking Down the Ingredients
- Dark chocolate: : Rich and intense, it creates that deep chocolate flavor and glossy finish. Swap for semi-sweet if you prefer milder.
- Butter: : Adds moisture and a tender crumb. Salted butter balances the sweetness, but unsalted works too.
- Eggs: : Bind everything together, giving that fudgy texture. Use fresh for best rise.
- Sugar: : Sweetens and helps develop that shiny crust. Brown sugar adds a caramel note if you prefer.
- Flour: : Gives the brownies structure. Consider almond flour for a nutty twist.
- Crushed cookies: : Adds crunch and nostalgia. Graham crackers or digestive cookies are classic.
- Vanilla extract: : Enhances everything with a warm aroma. Vanilla bean paste can elevate the flavor.

Cooking Checkpoints & Tips for Success
- Brownie edges should be firm and slightly crackly when done.
- Center jiggle indicates a gooey, fudgy interior—don’t overbake.
- A faint chocolate aroma signals it’s nearly ready.
- Use a toothpick to check doneness; a few moist crumbs are perfect.
Common Mistakes & How to Fix Them
- Leaving brownies in too long.? OVERBaking leads to dry brownies; remove from oven when edges are set.
- Not baking long enough.? Underbaking makes them too gooey; bake a few minutes longer.
- Adding eggs straight from the fridge.? Using cold eggs causes lumps; whisk eggs well before adding.
- Over-processing toppings.? Crushing cookies too finely; leave some chunks for texture.

Ingredients
Equipment
Method
- Preheat your oven to 180°C (350°F) and line an 8-inch square baking pan with parchment paper, leaving some overhang for easy removal.

- Chop the dark chocolate into small pieces and melt it together with the butter in a saucepan over gentle heat, stirring until smooth and glossy. The aroma of rich chocolate will fill your kitchen as it melts.

- In a large bowl, whisk the eggs and sugar together until the mixture becomes slightly frothy and pale, about 2-3 minutes. This helps incorporate air for a tender crumb.

- Pour the melted chocolate and butter mixture into the egg mixture, gently folding until well combined and smooth, releasing a rich chocolate scent.

- Stir in the vanilla extract if using, then sift the flour over the batter and fold it in gently until just incorporated, avoiding overmixing to keep the brownies tender.

- Pour the batter into the prepared pan, spreading it evenly with a spatula. The batter should be thick but spreadable, with a glossy finish.

- Sprinkle a handful of crushed cookies evenly over the top, pressing them slightly into the batter to ensure they stick during baking and add that nostalgic crunch.

- Bake the brownies for about 25-30 minutes, until the edges are set and slightly crackly, but the center still jiggles when gently shaken. The house will fill with a deep chocolate aroma.

- Remove the pan from the oven and let it cool in the pan for 15 minutes. This helps the brownies set and develop their chewy, gooey texture.

- Transfer the brownies to a wire rack using the parchment overhang and allow them to cool completely. As they cool, the crackly top will become firm, contrasting with the soft interior.

- Slice into squares and enjoy the perfect balance of crispy top and gooey, fudgy center—best served with a glass of milk or your favorite cold beverage.
