Ingredients for Your St Patrick’s Day Treats

Alright, let’s get down to what you’ll need. This is the easy part, I promise! Here’s the lineup for these awesome st patrick’s day treats:

1 box (18-20 oz) brownie mix (whatever your favorite brand is!)
1/2 cup water
1/4 cup vegetable oil
2 large eggs
1 container (12-16 oz) green frosting
Green sprinkles (because, duh!)

How to Prepare These Festive St Patrick’s Day Treats

Okay, here’s where the magic happens! Don’t worry, it’s not *real* magic, just easy-peasy baking magic. Follow these steps, and you’ll have amazing st patrick’s day treats in no time!

Preheat the oven to 350 degrees F (175 degrees C). This is super important! You don’t want to put your brownies in a cold oven. Give it time to heat up properly. I usually turn mine on as soon as I gather my ingredients so it’s good to go.
Mix brownie batter. In a large bowl, combine the brownie mix, water, oil, and eggs. Now, don’t just haphazardly throw everything in! I like to add the wet ingredients first, then the mix, to avoid getting a face full of brownie powder. Mix until *just* combined. Don’t overmix! Overmixing leads to tough brownies, and nobody wants that. A few streaks of brownie mix are okay.
Pour into a greased pan. Grab an 8×8 inch baking pan (or similar size). Grease it *really* well! I’m talking butter, oil, cooking spray – whatever you’ve got. You do NOT want these sticking. Alternatively, line the pan with parchment paper, leaving some overhang on the sides. Makes removing them a breeze! Pour that gorgeous brownie batter into the prepared pan and spread it out evenly.
Bake! Pop the pan into your preheated oven and bake for 25 minutes. Now, this is where you gotta pay attention. Every oven is different, so start checking around the 23-minute mark. You want a toothpick inserted near the center to come out with *slightly* moist crumbs. If it’s totally clean, you’ve overbaked them! Oops! Still edible but not as fudgy.
Cool COMPLETELY. This is the hardest part, I know! But trust me, you MUST let the brownies cool completely before frosting. Otherwise, the frosting will melt into a gloppy mess. And we don’t want that. Place the pan on a wire rack and just…be patient. Maybe go do the dishes or something.
Frost and sprinkle! Once the brownies are 100% cool (seriously, touch them!), grab your green frosting and slather it on! I like to use a butter knife or an offset spatula for this. Then, immediately add those green sprinkles! The frosting acts like glue, so you want to get those sprinkles on there before it sets. Go wild!
Cut and serve! Use a sharp knife to cut the brownies into squares. Wipe the knife clean between cuts for nice, neat squares. And that’s it! You’ve got delicious, festive st patrick’s day treats. Enjoy!

Tips for the Best St Patrick’s Day Treats

Want to take these st patrick’s day treats from good to *amazing*? I’ve got a few tricks up my sleeve that will make all the difference!

Don’t Overbake! Seriously, this is brownie rule #1. A slightly underbaked brownie is a million times better than an overbaked one. Keep an eye on them, and when a toothpick comes out with moist crumbs, they’re ready!
Cool Completely, I Mean It! I know I already said it, but it’s worth repeating. If you frost warm brownies, you’ll have a melty, sticky mess. Patience, grasshopper!
Gel Food Coloring is Your Friend. If you want a REALLY vibrant green, skip the liquid food coloring and go for gel. A little goes a long way, and it won’t thin out your batter. Plus, that bright green is super festive

Variations for Your St Patrick’s Day Treats

Okay, so you’ve mastered the basic green brownie – now what? Time to get a little wild! The beauty of these st patrick’s day treats is that they’re super adaptable. Here are a few ideas to kick things up a notch. Trust me, you’ll love these twists!

Chocolate Chips Galore! Everything’s better with chocolate chips, right? Toss in a handful (or two!) of your favorite chocolate chips into the batter before baking. Milk chocolate, dark chocolate, even white chocolate – go crazy!
Sprinkle Magic. Green sprinkles are classic, but who says you have to stop there? Use a mix of green, white, and gold sprinkles for extra shimmer and shine. Or, find some cute St. Patrick’s Day-themed sprinkles!
Cream Cheese Swirls. Oh. My. Goodness. This is my favorite part Let me tell you a secret: cream cheese frosting takes brownies to a whole new level of decadence. Whip up a batch of cream cheese frosting (or even use store-bought!), dollop spoonfuls over the brownie batter, and swirl it in with a knife or toothpick. Check out these cream cheese swirl brownies for inspiration! Seriously, do it.

Make-Ahead and Storage Tips for St Patrick’s Day Treats

Want to get ahead on your St. Patrick’s Day baking? These st patrick’s day treats are perfect for making in advance! You can bake the brownies a day or two ahead of time, let them cool completely, and store them in an airtight container at room temperature. Hold off on frosting until you’re ready to serve, though. Already frosted? They’ll keep in the fridge for 3-4 days! Freezing works too! Just wrap the cooled, unfrosted brownies tightly in plastic wrap and then foil. They’ll last for up to 2 months. Thaw them completely before frosting (or enjoying plain!).

Frequently Asked Questions About St Patrick’s Day Treats

Got questions about making these super fun st patrick’s day treats? Don’t worry, I’ve got you covered! Here are answers to some of the most common questions I get asked. And if you have more, just leave ’em in the comments below!

Can I use a different type of frosting?

Absolutely! If you’re not a fan of green frosting (gasp!), you can totally use a different color or flavor. Chocolate frosting would be decadent, or you could even go with a simple vanilla buttercream. Heck, even a dusting of powdered sugar works in a pinch! It’s St. Paddy’s day, a traditional Irish dessert like a Baileys cheesecake would also work great!

Can I make these gluten-free?

Yep, you sure can! Just use a gluten-free brownie mix. There are tons of great options out there these days, and they work just as well as the regular stuff. Be sure to check the label on your sprinkles, too, as some sprinkles contain gluten.

How long will these last?

If you store them properly (in an airtight container), these st patrick’s day treats will last for 3-4 days at room temperature. If you want to keep them longer, pop them in the fridge – they’ll stay fresh for up to a week! But let’s be honest, they probably won’t last that long because they’re so yummy!

Can I add anything else to the batter?

Go for it! Nuts, chopped-up candies, even mini marshmallows would be delicious additions to these st patrick’s day treats. Just don’t get too crazy – you don’t want to overload the batter!
