Each Chapter in the beginning, I will say how old the kids are or when it is place if there is no kids in the one-shot.

Liam: 15

Jo & Megan: 13

Disclaimer: I DON'T own Castle

"Okay, Make sure you lock the doors after we leave." Kate said, walking in her dress, at the kitchen.

Castle and Kate are going on a date night for their wedding anniversary. Liam, Jo, and Megan sat at the bar in the kitchen, waiting for them to leave.

"Don't worry, Mom. We've done this before." Liam groaned as the twins nodded in agreement.

"Don't open the doors to strangers. Don't leave the loft unless it's an emergency. Don't-" Kate rambled as walking towards the door with Castle.

"We got it, Mom. We know what to do. Have a good night." Liam said, following them. "Okay. Bye kids." Kate sighed and waved at them. Castle waved at them as well.

They started to leave but Castle stopped and turned to Liam.

"And don't. Don't break the video game console like you did last time." He stared him down and Liam gulped.

Kate pulled Castle ears and dragged him out. "Bye!" They both yelled. Liam shut the door after that.

He walked towards the twins in the living room. He saw them watching TV and took the remote and turned it off.

"Hey!" They both shouted at the same time. "What are you doing?" They said, still at the same time.

"Tonight. Mom and Dad are out for a date. Which means that we will find Dad's treasure." Liam confirmed, standing in front of the girls.

"What? His laser tag?" Jo said.

"His hairspray?" Megan added.

"His secret wardrobe?" Jo continued.

"No. No. None of that!" Liam interrupted. "His recipe for smorelette." The three kids were the only ones who actually liked it. Love it even.

"Yeah. I doubt we'll find it. He never tells anyone." Megan doubtfully said, taking the remote out of Liam's hand.

"C'mon, Dad can be pretty predictable when it comes to hiding stuff. So maybe it's in the drawers at his desk." Liam pondered for more ideas.

"Maybe under his video game console." Jo questioned.

"Or maybe he just remembered how to cook it and doesn't need a recipe." Megan stated.

Liam and Jo looked a each other and looked at Megan. Soon, they were both laughing hysterically.

"Dad remembering a recipe? He can't even remember a grocery list!" Jo laughed.

Megan rolled her eyes and turned on the TV. After the laughing calmed down, Liam spoke up.

"Alright, you do what you want to do. Jo and I will search."

"You guys have fun at 'The Great Smorelette Recipe Hunt'". Megan said sarcastically, as they walked out of the living room.

Liam looked at Castle's office and pulled out the drawers and shoveled in.

"Nothing here." He sighed, closing all the drawers.

Jo looked under the video game console. Nothing. But she looked around it and open cases to see if it was in there. Still Nothing.

She groaned and met Liam in the kitchen. "Anything?" She asked him.

"Nope." He responded. "Maybe it's in one of his cookbooks." Liam opened a cookbook and looked through every page.

"Nothing." Liam and Jo sighed and sat on the bar in the kitchen. Soon after that, Megan walked in.

"Aw. Is someone sad that they can't find a silly recipe?" She taunted.

"Shut up." Liam and Jo said at the same time.

"I have an idea." Liam thought. He walked to the refrigerator and pulled out some eggs, butter, and milk. Then we got some graham crackers, chocolate, and marshmallows.

"What are you doing?" Jo asked.

"If we can't find the recipe, then we are going to figure out the recipe." Liam said mischievously.

"Can you believe it has been 16 years since we got married?" Beckett asked as they sat down at their reserve table.

"And we got three kids during that time." Castle beamed and picked up his menu. Kate smiled but suddenly had a weird feeling. Castle seems to notice.

"Everything okay?" He asked, concern. Kate looked at him.

"I got this weird feeling that the kids are up to something." Kate admitted.

"They're fine. They are all teenagers. They are responsible enough to not burn down the loft." Castle reassured her and hold her hand. "For now, let's just enjoy our anniversary."

Beckett smiled at him again and looked at her menu. But she still got that feeling.

"THAT'S THE THRID ONE YOU BURNT!" Megan yelled at Liam. "WE SHOULD STOP BEFORE WE BURN DOWN LOFT!"

"I'm sorry! I just don't know how he put the graham crackers in and how he flipped the egg." Liam rambled, trying to clear the smoke out with the help of Jo.

"You know, maybe Megan is right. Maybe this is a bad idea." Jo confessed.

"No. This is our only chance to figure it out." Liam pointed out.

"But Mom and Dad is going to be here in like an hour. So let's get this place to smell like something that's not smoke!" Megan shouted.

"I will make it this time. You two keep trying the clear the smoke. I will make the next one." Liam started working to cook.

"Okay. So I got the egg cooking." He whispered. "I put the grahams over it, and now I put the chocolate in. And now-" Just then, he was interrupted by a loud beeping noise.

"Oh great. Now you've managed to get the fire alarm to noticed!" Jo yelled over the noise. All three of them grabbed a towel and tried to blow the smoke away.

Once they thought cleared it, smoke from the stove started to come out.

"Crap!" Liam ran to pick up the frying pan. Then, the three heard the door opened. They all panicked and turned around, thinking it was their parents.

But it was Alexis.

"WHAT IS GOING ON?" Alexis shouted, walking towards the smoke to clear it.

"We were trying to make a smorelette but we can't figure it out." Liam stuttered.

"Oh for the love of god! You know can't do that without Dad." Alexis said strictly.

"Okay. All four of us need to-" Alexis was interrupted by the scary voice of their Mom.

"WHAT IS GOING ON?" Beckett stormed in with Castle and stood in front the the four. "Explain this."

Alexis, Megan, and Jo pointed at Liam. Liam pointed at Megan and Jo. The parents stared at Liam.

"Okay. We were trying to make a smorelette but we couldn't figure it out!" Liam got his knees in front of Kate. "I'm sorry, Mommy! Please forgive me. I love you!" He cried.

"Liam, get up!" Kate grabbed his ear and pulled him up. Liam finally stood and looked down at his Mom.

"Clean this up. Try to stop the fire alarm and then talk to us." She stared up at him. Liam nodded and rushed to the kitchen.

"And you two," Kate pointed at the twins. "Help your brother. You know you were helping him."

The twins didn't argue and ran to the kitchen. Beckett turned to Castle.

"So much for your smorelette! If it wasn't for it, none of this would happen!" Castle put his hands in the air.

"Well, don't shoot me for it." Castle defended. Beckett rolled her eyes.

Once the kitchen was clean and smoke-free, The five sat in the living room. Alexis left after the incident.

"Alright, we left for one date and trust you to not do anything bad. But then we came home into this! What do you have to say for yourselves?" Kate said, walking in the front of kids while Castle stood there.

"Liam started this!" The twins shouted at the same time.

"I just wanted a smorelette!" Liam cried. "So we looked around for an recipe."

"There's no recipe for it. I just remembered how make it." Castle confessed.

Megan looked at Liam and Jo and smirked.

"But you can't even remember a grocery list!" Jo stated.

Kate laughed. Castle looked at her.

"Well, I mean, they do have a point." Kate admitted.

The kids started laughing along.

Castle rolled his eyes and sat down on one of the chairs.

"So can you teach us how to make it, Dad?" Liam asked with his big blue eyes.

"After that, no. But maybe this weekend." Castle said, tiredly.

The kids got excited and thank their dad.

"Alright, now go to bed." Kate said, pointing at the stairs. The three said good night and went to bed.

"Way to go, Castle. You told me not to worried about the loft burning down and that almost happened." Beckett said as they walked into their room.

"Oh whatever. But in case you forgot, it is our anniversary." Castle said, shutting the door of their bedroom. "And I think we got plans tonight."

Castle grabbed Kate to the bed and kissed her.
