Guinness Brownies with Peanut Butter Buttercream


There is a little bit of Irish in all of us on St. Patrick’s Day. Perhaps we can thank the luck of the Irish for blessing us with this mouth-watering dessert! Raise your pint of Guinness to all things peanut butter!

Note to all the sweet-tooth lovers: we’ve used minimum required sugar here so this brownie is on a rich and flavoursome side, not sugary. 

Note to everyone on a gluten-free diet: although chocolate itself is without gluten, it is often mixed with ingredients that do contain it. If you want to make this brownie gluten free, make sure you buy high quality, gluten free 85% dark chocolate.



For Brownie

1 c. Guinness Stout

250g dark chocolate, chopped

1 c. unsalted butter

1/2 c. cane sugar

3 large eggs

1 tsp. vanilla extract

3/4 c. all-purpose flour (skip this step if you want it gluten-free)

1 tsp. sea salt

For Cream

3/4 c. icing sugar

1 c. unsalted butter

2 tbsp. peanut butter

Line a 10 x 8 baking tray with baking parchment. Preheat oven to 350°F.

In a medium saucepan, bring the Guinness to boiling. Stir frequently until reduced by half. Remove and let it cool.

Place a medium heat-safe mixing bowl over a saucepan of simmering water. Add chocolate and 1 cup of butter to the bowl. Stir until melted and smooth.

Whisk together eggs, sugar and vanilla in a large mixing bowl. Slowly whisk in the chocolate/butter mixture until thoroughly combined. Then stir in 1/3 cup of the reduced Guinness stout. Gently fold in flour and sea salt.

Pour into baking dish, and bake for 45 minutes until the surfaces begin to crack and cake tester comes out almost clean. Cooking time may vary depending on thickness.

Remove from oven and place on a wire rack. Brush the top of the brownies with the remaining Guinness stout. 

Let it cool completely. 

For the cream, Add: 1 c. room temperature butter, 1 c. icing sugar and some ManiLife peanut butter (thought we’d forgotten!?) into a blender. Mix together on low speed while adding icing sugar until desired consistency is reached (think: THICK). Spread on top of the brownies and serve with a pint of Guinness!
