What You’ll Need
Grab your apron and let’s gather the goods! Here’s what you’ll need:
- ½ cup old-fashioned oats
- ¾ cup boiling water
- ½ cup + 3 tablespoons all-purpose flour
- ½ teaspoon baking soda
- ¼ teaspoon baking powder
- ¼ teaspoon fine sea salt
- ½ cup mini semi-sweet chocolate chips
- ¾ cup light brown sugar (packed)
- 3 tablespoons unsalted butter (softened)
- 2 tablespoons creamy peanut butter
- 1 large egg
- 2 teaspoons vanilla extract
- ¾ cup creamy peanut butter
- ½ cup unsalted butter (softened)
- 3 ¼ cups powdered sugar
- 5 tablespoons heavy cream
- 1 teaspoon vanilla extract
- 1 cup mini M&M’s
- ¼ cup mini semi-sweet chocolate chips
Let’s Figure This Out Together
Alright, let’s break this down step by step. Follow along, and we’ll do this together:
- Place the oats in a medium-sized heat-proof bowl. Pour the boiling water on top and let it sit until it cools to room temperature, about 90 minutes. (This step is crucial for achieving that chewy texture!)
- Preheat the oven to 350°F. Line a cupcake tin with liners, and set aside.
- In a small bowl, whisk together the flour, baking soda, baking powder, and salt.
- Add the chocolate chips to a small bowl. Add 1 tablespoon of the flour mixture and stir to combine so all the chocolate chips are coated, then set aside.
- In a large bowl, cream together the brown sugar, butter, and peanut butter until smooth using an electric hand mixer. (I once skipped this step and ended up with lumpy cupcakes—trust me, don’t skip it!)
- Add the egg and vanilla, mixing until smooth.
- Add the cooled oatmeal and mix it in. (Make sure it’s not too hot, or it will scramble the egg!)
- Then, add the flour mixture, and mix it in until there are no dry patches.
- Add the chocolate chips and stir them in until just combined.
- Divide the batter among the 12 cupcake liners in the tin, about 3 tablespoons each.
- Bake for 14-17 minutes until a toothpick inserted into the center comes out clean. Let cool in the tin for 10 minutes, then take them out to cool completely on a wire rack.
- Once the cupcakes are cool, make the frosting. Place the peanut butter and butter into the body of a stand mixer or into a large bowl with an electric hand mixer, and mix until smooth.
- Add the powdered sugar a little at a time until mixed in. Scrape down the sides as needed.
- Add the heavy cream and vanilla, slowly stirring it in. Once it’s incorporated, turn up the speed to medium-high and whip for 3 minutes until light and fluffy.
- Add the chocolate chips and M&M’s; I like to fold these in by hand until incorporated.
- Top the cupcakes generously with the frosting. I like to use an ice cream scoop to do this. The chunks from the chocolate chips and M&M’s are too big to pipe the frosting. Serve immediately!
Real Talk: What Actually Works
Now, let’s get real for a second. Baking can be a bit finicky, but you can totally do this! Here are some tips I’ve learned along the way:
Don’t skip the fun stuff: Coating the chocolate chips in flour helps keep them from sinking to the bottom of the batter. It’s a small step, but it’s a game changer!
Room temp ingredients: Make sure your butter and eggs are at room temperature. This helps to create a smoother batter and makes a noticeable difference in texture.
Know your oven: Every oven is different. Start checking your cupcakes around the 14-minute mark. If they’re not done, keep an eye on them; you want that perfect golden color.
Customization is key: Feel free to swap in different candies or nuts if you’re feeling adventurous. Want to use white chocolate chips instead? Go for it! Just remember to maintain the balance of dry and wet ingredients.
Leftovers and Storage Reality
So, what happens if you have leftovers? Honestly, they don’t last long in my house, but if you manage to save some, here’s what to do:
Store the cupcakes in an airtight container at room temperature for up to 3 days. They’re best enjoyed fresh, but they’ll still be tasty for a couple of days.
If you want to store them longer, you can freeze them without the frosting for up to 3 months. Just make sure they’re well-wrapped!
When you’re ready to enjoy them, let them thaw at room temperature, then frost them when you’re ready to serve.
Questions I’ve Actually Gotten
Can I make these cupcakes gluten-free?
Absolutely! Just swap out the all-purpose flour for a gluten-free blend. It should work just fine, but I’d recommend checking the package for any specific instructions.
What if I don’t have mini chocolate chips?
No worries! You can use regular chocolate chips. Just chop them up a bit if they seem too big to mix in.
Can I make the frosting ahead of time?
Yes! You can prep the frosting a day in advance. Just keep it in the fridge in an airtight container, and whip it up again before frosting the cupcakes.
Is there a way to make these healthier?
You could try substituting some of the butter with applesauce and using a natural sweetener instead of brown sugar. Just keep in mind, it might alter the texture a bit.
Closing reflection
So there you have it! These Monster Cookie Cupcakes are a fun, indulgent treat that’s easy to make and sure to impress. Trust me, once you take that first bite, you’ll be hooked. Whether you’re making them for a special occasion or just because you’re in the mood for something sweet, these cupcakes are a win.
And remember, even if things don’t go perfectly (because let’s face it, they rarely do in my kitchen), you’re still going to end up with something delicious. So roll up your sleeves, put on your favorite playlist, and get baking! You’re going to love these.
