- 100g plain flour

Step-by-Step Mary Berry Brownie Recipe Guide (Easy & Detailed)
These brownies follow a classic traybake approach — perfect for all levels of home bakers.
Step 1 — Prepare the Baking Tin
- Line a 20 × 30 cm tray with parchment paper.
- This helps with easy removal and clean slicing.
- This step is essential for brownie pan preparation.
Step 2 — Melt Chocolate and Butter
Place the butter and chocolate in a heatproof bowl over simmering water.
This chocolate melting method avoids burning and ensures smoothness.
Anecdote:
I once rushed this step by melting chocolate directly in a pan… let’s just say it became a grainy disaster. Since then, I’ve trusted this gentler approach — and it has never failed.
Step 3 — Add Sugar
Stir in the sugar until dissolved.
This helps achieve a glossy brownie top later.
Step 4 — Add Eggs and Vanilla
Beat in eggs one at a time.
This prevents curdling and keeps the brownies silky.
Add vanilla extract for flavour balance.
Step 5 — Add Dry Ingredients
Sift together flour, cocoa, and salt.
Fold gently (not whisk!) to avoid introducing too much air.
This is key for maintaining how to achieve fudgy brownies.
Step 6 — Fold in Walnuts
Add chopped walnuts.
For better distribution, try light flour coating to prevent sinking.
Step 7 — Bake
- Bake at 180°C (350°F) for 25–30 minutes.
- Remember brownie baking time and temperature may vary by oven.
- Brownies are done when the top is set but the centre is slightly soft.
Step 8 — Cool Completely
Proper cooling is part of proper cooling technique for brownies.
Cooling firms them up and prevents crumbly slices.

FAQs
Why are my brownies turning cakey instead of fudgy?
Brownies become cakey when you overmix the batter or bake them too long. Fold gently after adding the dry ingredients and remove them from the oven while the centre is still slightly soft.
How do I get that shiny, glossy top on my brownies?
A glossy top appears when sugar dissolves properly into the warm chocolate–butter mixture. Mix well while the chocolate is still warm to achieve that shiny finish.
Should I toast the walnuts before adding them?
Toasting is optional but recommended. Lightly toasting walnuts enhances their flavour and keeps them crunchier inside fudgy brownies.
How do I know when the brownies are perfectly baked?
The edges will look set, and the centre will feel slightly soft when pressed. A skewer inserted should come out with moist crumbs, not fully clean.
Why did my walnuts sink to the bottom?
Walnuts sink when the batter is too thin or when they are added without coating. Toss them lightly in a spoonful of flour before folding them into the batter.
How do I prevent brownies from crumbling when slicing?
Let the brownies cool completely. Warm brownies crumble because the structure hasn’t set yet. Use a sharp knife and clean it between cuts.
Can I make these brownies without nuts?
Yes, simply omit the walnuts or replace them with chocolate chips, dried fruit, or other mix-ins.
Can I freeze Mary Berry walnut and chocolate brownies?
Absolutely. Wrap individual pieces tightly and freeze for up to 2 months. Thaw at room temperature for best results.
Why is my brownie centre too raw?
Your oven temperature may be too high, or the tray may be too small, causing uneven baking. Bake on the middle rack and check 5 minutes before the suggested time.
Can I use milk chocolate instead of dark chocolate?
Yes, but the brownies will be sweeter and slightly less rich. Dark chocolate gives the deepest flavour and best fudgy texture.
