Peanut Butter Mousse Brownies

Chocolaty Peanut Butter Mousse Brownies are stuffed with Reese’s Peanut Butter Eggs and topped with a creamy No Bake Peanut Butter Mousse.

Peanut Butter Mousse BrowniesI must confess, I love brownies, I am actually obsessed with brownies and I might’ve just developed an addiction to these Peanut Butter Mousse Brownies stuffed with Reese’s Eggs. If you check my brownie recipes, you can see that I have Chocolate Mousse Brownies, Red Velvet Creme Brûlée Brownies (yes, I went that far!), I also have 7 Layer Brownies, Pomegranate Mousse Brownies a Brownie Cake and Brownie Cupcakes. Well, those are a lot of brownies in one paragraph, but all of them are unbelievably good.

If you have been a reader for some time, you also might’ve noticed that I have a thing for mousse. Mousse makes everything so much better! I mean, its sweet, its creamy and it adds another level of taste and texture, its good on its own, but its even better when combined with other desserts, just like in these Peanut Butter Mousse Brownies that are topped with a thick layer of No Bake Peanut Butter Mousse.

With Catholic Easter just around the corner, if you are like me you stocked up on Reese’s Eggs, cause that stuff is insanely delicious. And if you are like me, you will end up with a basket full of candies, that you can either eat, hoard or much better bake them into brownies.

Seriously, these brownies are amazing! A cross between peanut butter brownies and peanut butter pie, its actually combining both in this easy and indulgent dessert. The brownies are extra chocolaty, with huge bites of Reese’s Eggs, and every single bite is topped with a huge amount of creamy and delicious peanut butter mousse.

  9. In a separate bowl, whisk on medium speed cream cheese, peanut butter and confectioner's sugar, reduce speed to low and add ½ cup of heavy cream, mix on medium low speed until fully combined. Stop to crape the sides of the bowl with a spatula.
  10. Gently, using a spatula, manually fold in the whipped cream into the peanut butter mixture. Gently still until well blended.
  11. Pour the peanut butter mousse on top of the completely cooled brownie pan and level the top layer. Place in the fridge overnight, or for at least 4-6 hours.
  12. Before serving, remove from fridge, lift the mousse brownies from the pan using the parchment paper edges, dust with cocoa powder, run a knife thru cold water and cut into square bars.
