Dark Chocolate Walnut Blondies are rich, gooey and decadent. Undeniably more-ish, this easy to make, one- bowl, small batch recipe will be a hit with the kids and adults alike.
The brown sugar adds a rich intense, molasses flavour that is cut through with the dark chocolate chunks. The walnuts add a textural dimension along with the added nutty taste- such a bonus!
What ingredients are in Dark Chocolate Walnut Blondies?
Dry ingredients:
- Flour: stableises and bulks out the blondies
- Baking powder: adds extra leavening to them
- Salt: Always a necessary addition to sweet bakes
- Sugar: Brown sugar is used for that extra intense molasses flavour
Wet ingredients:
- Eggs: One whole egg is used as a binding agent plus an extra yolk for richness
- Vanilla Extract: For taste
Add-ins:
- Dark Chocolate: To cut through the sweetness but milk chocolate can be used if preferred.
- Walnuts: For added flavour but also textural crunch


How to make these blondies
I have to say that these are so easy to make. Like one bowl easy to make. In just a couple of steps and in under an hour, you can enjoy these blondies at home.
These Dark Chocolate Walnut Blondies have been made in small batch quantities. But if you’d prefer to make a standard serving then simply double the recipe. Instead of 1 egg and 1 yolk, use 3 whole eggs instead. This minimises the wastage which I prefer.
Step 1: Mix your brown sugar and butter together.
Step 2: Add wet ingredients (eggs and vanilla extract) and stir.
Step 3: Sift into bowl dry ingredients (flour, baking powder and salt). Stir to combine.
Step 4: Add the add-ins, chocolate and walnuts, setting aside 1 teaspoon of each.
Step 5: Pour batter into a greased and lined loaf pan and sprinkle over remaining chocolate and walnuts. Bake for 22-25 minutes for a soft centre, or for 5-8 minutes longer for a more set centre. Cool in pan before cooling on a wire wrack.
I truly hope that you love this recipe. If you love chocolate chip cookies, then the flavour profile of this will remind you of them. The morsels of melted dark chocolate and the crunch of the walnuts are the perfect addition to elevate each bite.

Subbing Ingredients
Brown Sugar: If you don’t have brown sugar then light brown or golden caster will do.
Dark Chocolate: I know my kids aren’t a fan of the bitter notes of dark chocolate and prefer the sweeter milk chocolate. I however, prefer the bitter dark taste against the sweet interior of the blondie. Either will work- take your pick!
Walnuts: Sub these with any nuts of your preference such as pecans, hazelnuts or almonds. Or leave out altogether if you prefer.

Description
Dark Chocolate Walnut Blondies are rich, gooey and decadent. Undeniably more-ish, this easy to make, one- bowl, small batch recipe will be a hit
THIS SMALL BATCH RECIPE CAN BE DOUBLED IN SIZE TO MAKE A REGULAR SERVING SIZE OF 12
Ingredients
60g butter, melted
80g brown sugar
110g plain flour
¾ teaspoon baking porder
¼ teaspoon salt
1 egg plus 1 egg yolk, beaten
1 teaspoon vanilla extract
100g dark chocolate chopped
70g walnut halves, chopped
Pinch flaked sea salt, optional
Instructions
- Preheat oven to 180C/350F. Grease and line a 2lb (9 x 5.5 inch) loaf pan with grease proof paper. (Tip: leave an overhang on the sides so that it makes it easier to lift the blondies out afterwards.)
- In a large bowl combine the melted butter and sugar and stir together. Add the egg and vanilla extract and stir again.
- Sift the flour, baking powder and salt into the sugar mixture bowl and stir until just combined.
- Add chopped chocolate and walnuts, reserving some of each to sprinkle on the batter after. Fold the chocolate and nuts into the batter. Pour batter into your prepared loaf pan and sprinkle with remaining chocolate chunks and walnuts, pressing gently into the batter.
- Bake for 22-25 minutes until set around the edges and with a slight jiggle in the centre. This ensures fudgy centres. Cook for 5 more minutes if a more set centre is preferred. Remove from the oven and allow to cool in the pan for ten minutes. Gently use the baking paper sling to lift the blondies out of the pan and onto a wire baking tray to cool before cutting.
- Sprinkle with flaked sea salt before serving.
Notes
- To double this recipe. Double all the ingredient. For the eggs use 3 eggs beaten. Bake according to the instructions. Grease and line a square 9×9inch brownie pan to bake the blondies.
- For neat slices/squares: Refrigerate the blondie for one hour or more. Then cut into slices – the blondies will have much neater edges.
- To Store: Store Blondies in an air tight container for up to 3 days at room temp or 5 days in the refrigerator.
- To Freeze: Cut blondies into squares or slices. Wrap individual slice in parchment paper and store in an airtight container. Freeze for up to 3 months. To de-frost, thaw overnight in the fridge. Microwave for a couple of seconds to get that gooey interior.
