Peanut Butter Frosted Brownies

When I was a kid, my school cafeteria sometimes served a peanut butter and chocolate graham cracker square for dessert.  You could only get them on certain days and only if you bought the lunch.  They were so good that I’d specifically buy lunch on those days even if I didn’t like the lunch option.  Ever since that dessert, I’ve been a huge peanut butter and chocolate fan.

These peanut butter frosted brownies take me back to when I was a kid and I adore them every bit as much as those cafeteria desserts.  These fudgy brownies are topped with sweet peanut butter frosting and they are my new favorite dessert.     🙂

I’m in love with my Fudgy Brownie recipe.  I have made it a bazillion times (i.e. a lot) and just by themselves they are sheer chocolate perfection.  Now I’ve taken that brownie base and added some sweet peanut butter frosting on top.

This brownie recipe is as easy as box mix, but tastes better.  Melt the butter and chocolate chips.  When I make Fudgy Brownies, I don’t melt the chocolate chips because they melt on their own while baking which leaves little pockets of chocolate.  However for today’s brownies I wanted to make sure the brownie consistency was 100% smooth and fudgy so I decided to melt the chocolate chips.

Stir in the sugar and vanilla extract.  The batter will look gritty.  Beat in the eggs.

Add the flour, cocoa powder, and salt and stir until just combined.  I love how you only need one bowl to mix all the ingredients.

Spread the brownie batter evenly and bake it.

Are you ready for the perfect peanut butter frosting?  You only need four everyday ingredients and it’s super simple to make.  Beat the peanut butter and butter until it smooth.  Then add the vanilla extract and powdered sugar until it is combined well.

Make sure the brownies have cooled completely before you frost them.  I sprinkled some miniature chocolate chips on top for a little crunch, but mostly for presentation points.     🙂

This brownie is so moist and fudgy.  Need I say more?  If you’re looking for a chocolate piece of heaven then that’s your answer…Fudgy Brownie to the rescue again.

The fudgy brownie is…well, grand in all its fudgy-ness and as I said earlier, really amazing by itself.  However, the frosting makes this dessert.  It’s thick, smooth, and full of peanut butter flavor.  I could eat this by the spoonful (and might have).     😉

The moment your lips hit the frosting, it’s all over.  Peanut butter lovers, beware.  You may hear harps when you eat this sweet dessert.  The sweet frosting is a perfect match with the richness from the chocolate fudgy brownie.
