Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.
Step 1 – Prepare The Peanut Butter Mix
Preheat oven to 160 degrees celsius (fan-forced) and line a 20cm square tin with baking paper. Set aside.
Place the butter and peanut butter into a microwave-safe bowl. Heat for 1 minute to melt.
If using a Thermomix – Place the butter and peanut butter into the Thermomix bowl. Melt for 3 minutes at 80 degrees, Speed 2.
Step 2 – Add More Ingredients
Add the caster sugar and sifted cocoa powder and stir. Heat in the microwave on 30-second bursts (50% power) until the sugar has dissolved and ingredients combined – stirring each time.
If using a Thermomix – Add the caster sugar and cocoa powder and mix for 10 seconds on Speed 4. Scrape down the sides of the bowl and repeat for a further 10 seconds.
Allow to cool slightly.
Add the vanilla extract and the eggs and whisk until combined.
If using a Thermomix – Add the vanilla extract and the eggs and mix for 10 seconds on Reverse, Speed 4. Scrape down the sides and repeat.
Step 3 – Add The Flour
Sift the plain flour into the bowl and gently fold through.
If using a Thermomix – Add the plain flour and mix for 5 seconds on Speed 4. Scrape the sides of the bowl and repeat.
Step 4 – Bake The Brownies
Pour the peanut butter brownie mixture into the prepared tin. Dollop the extra peanut butter over the top of the brownie. Use a knife or a skewer to swirl the peanut butter through the brownie batter.
Bake for 25-30 minutes or until cooked through.
Leave in the tin to cool completely.
Expert Tips
- For extra peanut butter flavour, add some Reese’s Pieces or mini peanut butter cups to the batter.
- For an extra indulgent treat, serve these peanut butter brownies warm with a scoop of vanilla ice cream.
- For best results use store-bought smooth and creamy peanut butter.
- Don’t overcook the brownies – they should be dense and fudgy.
- Store in an airtight container at room temperature for up to 4 days or in an airtight container in the fridge for up to 5 days.
- Freeze in an airtight container for up to 3 months.
FAQ’s
What makes a brownie fudgy?
The fat-to-flour ratio is higher in fudgy brownies than in ‘cakey’ ones. In this recipe the ‘fat’ content comes from the butter, cocoa and peanut butter. A cakey batch uses extra flour and baking powder as the leavening agent. My peanut butter brownies contain no leavening agent, meaning that the brownies stay fudgy and dense!
Can I make peanut butter brownies in a Thermomix?
Absolutely! You can make my peanut butter brownies in a Thermomix or in a mixing bowl (both methods are included below).
How do I know if my peanut butter brownies are cooked?
The top of the brownies will be flakey and set. Insert a skewer into the centre of the brownie. If it comes out with moist crumbs on it (not wet) then it’s ready. The brownie will continue to cook while cooling. Do NOT overcook the brownies or they will lose their fudgy texture.
