    INGREDIENT NOTES

    These are some of the key ingredients for this recipe. For a full list of ingredients, check out the recipe card below.

    • Butter: The butter is melted and mixed together with the dark chocolate. 
    • Eggs: Take them out of the fridge 1-2 hours before baking.
    • Semi-sweet chocolate: I recommend a dark chocolate on the sweeter side, e.g. 54,5%, and therefore a not too bitter of a dark chocolate.
    • Cornstarch: Cornstarch breaks down the gluten in the flour, making for a more soft and fudgy brownie.
    • Cocoa powder: I use high quality dutch processed unsweetened cocoa powder for the best flavor, my favorite is from Valrhona.
    • Peanut butter: I recommend using a smooth natural peanut butter
    • Peanut Butter Cups: Use either Reese's mini or full size Peanut Butter Cupcakes.

    STEP BY STEP INSTRUCTIONS

    Here is how to make and bake this Chocolate Peanut Butter Brownies. This recipe needs an electric hand mixer or a stand mixer with a whisk attachment.

    The full recipe is down below in the recipe card.

    Before starting preheat the oven to 160ºC /320ºF conventional oven. Prepare a 20x20 cm square baking pan with parchment paper.

    STEP 1: Melt the butter and in a small bowl add chocolate chips to the butter. Let it melt together until smooth. Sift together the all purpose flour, cocoa powder, cornstarch and salt.

    STEP 2: In a large bowl, with an electric hand mixer, whisk together the large eggs, brown sugar and granulated sugar until light and fluffy for 4 minutes. Add the melted butter and chocolate, oil and vanilla extract into the batter and mix until combined. 

    STEP 3: Add dry ingredients to the batter and on the lowest setting gently mix it together until combined. Scrape down the sides of the bowl with a spatula.

    STEP 4: Pour half of the brownie batter into the prepared pan, smooth it out with the spatula to an even layer. Heat up the peanut butter for 1 minute in the microwave so it is more fluid. Pour the peanut butter on top of the brownie batter and spread it out. Add 15 mini peanut butter cups, cut in half. Then add the other half of the brownie batter and even it out.

    STEP 5: Bake for about 45-50 minutes. Immediately out of the oven drizzle with extra peanut butter and halved mini peanut butter cups on top of the brownies. Let it cool down completely on a cooling rack. Serve once it’s cooled down.

    EXPERT BAKING TIPS

    • Use a kitchen scale: My default setting for my recipes is grams. It is the most precise way of measuring out your ingredients, I therefore highly recommend using a kitchen scale.
    • Don't over mix your batter: I always use a spatula after everything has mixed together, to give it one final gentle fold together. This makes sure everything in the bottom of the mixing bowl has been mixed into the batter.
    • Light vs. dark baking pans: For the best result, use an aluminum baking pan, greased with butter and lined with baking paper in the bottom. Aluminum pans are light in color and therefore attract less heat. That means it bakes more gently which results in a softer cake. If you use a black baking pan it'll attract a lot more heat. That will then give a darker crust, which can result in a dryer cake.

    FAQ

    How do I know when it's done?

    You'll know the brownie is done, when the brownie has just set. When taken out of the oven, insert a butter knife and if it has wet batter on it, give it 5 more minutes but if it has moist crumbs on the knife it's done.

    Are they best cold or room temperature? 

    I personally love eating brownies cold, so they are also really good to make a day ahead of serving and storing them in the fridge overnight. They can also be stored at room temperature, if you prefer them not to be cold.

    Can it be made a day ahead?

    Yes, absolutely. As mentioned above, this brownie get super rich and fudgy by staying in the fridge overnight or at room temperature.

    Can I use almond butter instead of peanut butter?

    Yes absolute! Use it 1:1 with the peanut butter.

    STORAGE

    Here are two option on how to store the chocolate peanut butter brownies:

    • Room temperature: To keep these brownies fudgy I recommend storing it at room temperature in an airtight container. To keep the edges from drying out, I suggest waiting to cut them until you're ready to serve them. They will stay soft for 2-3 days when stored properly.
    • Fridge: I personally love a cold brownie. It tightens up the texture of the brownie and makes them extra fudgy. They are therefore really good to make a day ahead of serving. Just store them in the fridge overnight uncut.
