Don't worry cause here I have gathered 5 of the most fun ideas to opt for.
Just with a little creativity and imagination you can plan an ultimate surprise birthday party for your loved one, here are a few ideas that you can follow,

Let Your Kid Follow The Clues To Reach The Surprise Party

If your kid loves playing quests games or treasure hunts, this idea may prove to be his or her dream party that they'll never forget. Set up treasure hunt clues all along with the house that will lead to the area where you have set up the actual party while your kid is away, sleeping.
You will have to plan for everything ahead of time, start from the entrance of his or her bedroom, or somewhere they have their first glance when they wake up, it could be on a post-it note on the mirror. To make things more exciting and if you have the budget, try to put a little gift with every clue.
Set up alarms and hide in the party area before your birthday king/queen wakes up. The entire process will be memorable, and your kid will not forget about the experience he had. The joy of finding the big surprise in a form of a party will entice their mood to the fullest.

Breakfast Birthday Bash With Family

This one is the best idea and I like this a lot, if you want to have a surprise party only including the family members, then there’s nothing better than this. And your birthday kid day will be made.
It's simple if your kid is an early riser this can be the best surprise, he/she can have. This may be a little tiring for you but what's better than making your kid's day? Start by decorating the breakfast area and set up a themed breakfast with things your kid likes the most. Make sure to prepare your kid’s favorite breakfast. And don't forget about the cake, which kid doesn't wish to eat a cake full of frosting for breakfast?
This will be the ultimate dream come true for your kid. You can add a little more twist by making your kid think that you and other family members have forgotten about their birthday until they wake up on birthday morning.

How About A Movie Marathon With Your Loved Ones

This birthday idea includes your backyard or porch whatever place you want to incorporate in the plan. You can rent out an outdoor movie setup for the party, or you can simply buy one online or look out for one in your local Home Depot.
The next thing you need to do is, gather all the favorite movies of your birthday kid, or a new moving that your kid wishes to watch. Set up all the decorations and snacks. Make sure to get all the snacks that your kid love.
And, when the dark rise, it's showtime baby. Spend the night or evening watching your kid’s favorite movie after cutting the cake.

Plan A Fancy Dinner At Home Making It Look Like You Forgot The Birthday

If your kid's birthday is coming in between the weekdays, then this idea is best for you to surprise your kid. Make it look like a normal day and behave as if you have completely forgotten about their birthday. And when they are off to school prepare for the big surprise, get all the party supplies out, and start decorating the house or the backyard.
Invite some of your kid's favorite people, if you want to you can also ask your kid's friends to also be a part of the surprise and act like they don't know anything. And when they reach home surprise them with some confetti at the entrance and then to the party.

A Classic Magical Lights Out Never Goes Wrong

Plan a classic light out but with a twist, place a simple cake without much decoration and when your kid is going to cut the cake turn off the lights, switch the cake with a themed one and make your family help in placing small, themed decorations.
And when the lights will turn on it will look like the party is transformed magically. Call your kid's favorite people, like grandparents, favorite cousins, or a family member that lives far away to come and be a part of your kid's big day. Turn On the lights and have them appear behind them; they are truly going to love this surprise.
