Every day requires a bit of adventure, and some days are more adventurous than others… Especially when you have a preschooler.

I decided to make you something St. Patrick’s(y), and this one little brown-haired girl wanted to help. Thinking that I would change her mind about hanging around with me in the kitchen, I told her that this was one bowl of buttercream that she couldn’t lick.

Ana: WHY?!?

ME: Because there’s alcohol in this.

Ana: WHY?

ME: Because.

Ana: Because WHY?

ME: Because it’s St. Patrick’s Day and I am going to make boozy Fudge Brownies with Baileys Buttercream.


At this point I just lost it! I had not laughed that hard in a long time!

Our conversation went on for an entire hour. In the end I had to make a deal with her – she couldn’t have a brownie, but I would let her spread the buttercream on top. She came back with a counter offer – she wanted to put the buttercream in a pastry bag and pipe it, like she does with the gazillion cupcakes that we make almost every weekend. Deal.

Don’t you love how that frosting turned out on top? Pretty, right? ;-D

I don’t mean to toot my own horn, but I am convinced that these brownies are seriously the best. Ever. Everrrrr. It’s the buttercream. It’s freakin’ ahhhhh-mazin’.

You know, after having two brownies, I sorta felt a bit tipsy. Seriously. I went to have two more for the full effect.

  1. The brownies have good flavor but I always find that butter is bubbling up at the sides of the pans, and the corners of the brownies look crystalize. It never says to cream so I just mix the sugar and butter/chocolate mixture together as directed. Is there something I’m doing wrong? Because my brownies are more oily and moist (not a terrible thing) than fudgy.

  2. Oh. Em. Gee. These are incredible. They are the fudgiest brownies I’ve ever made and the buttercream is to die for. Made this for a Baileys-loving friend’s birthday….she’s going to LOVE them. Great recipe. Thanks!

    Made these last night and they were amazing! You should be very proud of your daughter – her frosting skills quite exceed mine and my boyfriends.

  4. Can I say how much I love that the buttercream is just a big huge blob on top of each brownie? That’s my kinda brownies, girl!

    Oh how I miss those days in the kitchen with my little ones!! I had so much fun with them, and I have the pictures to prove that they had just as much fun with me, though my son will deny it!
    LOVE these brownies, but I have to admit that her topping is the prettiest brownie topping I’ve ever seen. She takes after you!

    Love anything flavored with Bailey’s …even if it’s flavoring the ice in the glass. 😉 Great recipe. Easy and perfect for St. Patty’s celebrations. Yum!

    Oh wow these look amazing! I love chocolate and baileys together (I just made some chocolate cupcakes with baileys buttercream, but I think your brownies might just beat that!)

  16. Love your daughters final thought. LOL! I’m glad I’m an adult and I can enjoy them… and I don’t have to be a saint. 🙂

    I need to get some Bailey’s, because this looks so yummy. Your daughter rocks the pastry bag.

  19. Oh, boozy brownies! But how are you able to keep a bottle of Baileys around long enough to actually use it in baked goods?

    Love your silverware!

    I can’t wait to have conversations like that with Olivia. If I was her and I saw these brownies I would want some too.

    Saints drink alcohol. Yup, that’s a keeper. What a cutie. 🙂 The brownies do look amazing, but I have to say I was entranced by your frosting job. I seriously think it’s awesome. Your daughter’s a natural.
