Hi Bold Bakers!

Amazing, over-the-top cupcakes have been popular for years but my Crazy Cupcakes recipe is a real game changer! Why search for separate cupcake recipes when you can use this one to make delicious homemade cupcakes filled with your favorite flavors?

Not only will I show you how to make cupcakes, but this easy recipe will allow you to use your favorite flavors. Just like my Crazy Cookie Dough and Crazy Dough Recipes, this recipe is an easy recipe with endless possibilities.

What Are Crazy Cupcakes?

Crazy Cupcakes are made from one — yes, one — base cupcake batter that you can then turn into any flavor cupcake you want! I created this recipe to make it easier on everyone when you reach for a cupcake recipe — you can even make a batch of all different flavors for a picky crowd. The possibilities are truly endless.

What You’ll Need To Make Crazy Cupcakes

  • Cupcake Tray and Liners
  • Stand mixer with a whisk attachment
  • Measuring cups
  • Bowl

How To Make My Crazy Cupcake Recipe

My Crazy Cupcake recipe starts with a classic sweet sponge cake. This will act as your master recipe, your Best Cupcake recipe from now on!

This cake is fluffy, moist, and sweet, making it the perfect canvas for whatever flavors you and your family crave. And the end product is perfect for birthdays, special events, and so much more (and don’t forget to get the full recipe with measurements, on the page down below)!

  1. Preheat your oven and line a cupcake tray.
  2. In a stand mixer fitted with a whisk attachment, beat your butter.
  3. Add sugar, and cream the sugar and butter together in the stand mixer.
  4. One at a time, add your eggs before adding the milk.
  5. Add your dry ingredients.
  6. Add in extra flavor. Scoop in the batter in a bowl and add your mix-ins.
  7. Bake for 16 to 18 minutes before taking out and allowing to cool completely.

What Flavors Can You Make?

After you prepare the sponge batter you simply add in your choice of mix-ins. From classics like a vanilla cupcake recipe to fun flavors like Chocolate and Peanut Butter, I have you covered. My personal favorite is the Birthday Cake flavor!

What Flavor Frosting Can You Make?

All of these flavors are topped off with everyone’s favorite part: loads of frosting and extra toppings.

If you want to see all the flavors of frosting you can use, you have to check out my Crazy Frosting Recipe! I have a recipe for all your favorite frosting flavors from mint chip or coffee, to strawberry and of course chocolate!

Below are just a few of my flavor ideas but you can make so many more. Let me know in the comments below what you make!

Our Recipe Flavor Suggestions

The written recipe includes the master batter ingredients and instructions plus suggestions for 6 of my favorite flavors. Get creative and make your own as well! Here are some cupcakes I suggest you try making:

Red Velvet Cupcakes

Red Velvet Cupcakes are a classic, combining moist cake, a hint of cocoa powder, and cream or cream cheese-based frosting. The result not only looks so delicious and decadent with rich red color but tastes like chocolate heaven!

Lemon And Blueberry Cupcakes

Tangy lemon and sweet berries are one of my favorite combinations in this recipe! With its sweet lemon flavor, this easy recipe is a great one to make when berries are in season. However, if they aren’t you can always use frozen berries.

Carrot Cake Cupcakes

This happens to be one of my personal favorite flavors! I love the lightly spiced cake combined with the sweet grated fresh carrot. This carrot cake cupcake recipe is a great way to get in those extra veggies!

Cookies And Cream Cupcakes

The only thing better than a cupcake is one combined with an Oreo! That is exactly what these Oreo cupcakes are! Using crushed Oreos, they are rich, creamy and have a delicious chocolate flavor!

Birthday Cake Cupcakes

Another classic, these birthday cupcakes are so festive! I love to go crazy with the sprinkles here. There’s no such thing as too many sprinkles!

Chocolate And Peanut Butter Cupcakes

My husband, Kevin, loves chocolate and peanut butter, so this one was a must. These are a little salty, sweet, and pack that chocolate punch.

How To Store Them

After they’re decorated you can cover them in an airtight container and store them for up to 3 days. If you’d like you can freeze the baked and un-frosted ones for up to 3 weeks. To thaw, allow them to sit at room temperature until soft and fully defrosted. Once defrosted you can frost and enjoy!

Cookies and Cream Cupcakes


  • Preheat your oven to 350°F (180°C) and line a cupcake tray with cupcake liners.
  • In a stand mixer fitted with a whisk attachment beat your butter until fluffy.
  • Add your sugar and cream together the sugar and butter until light and pale in color.
  • Add your eggs one at a time, being sure they are fully incorporated between each one. Then add in the milk.
  • Add the dry ingredients and mix until a smooth batter is formed. Do not over-mix.

To flavor your cupcakes (This recipe makes 12 cupcakes with 1/4 c or 4 Tbsp of the base batter for each. The measurement for each flavor variation is for 1 cupcake. ) :

  • Scoop a 1/4 cup (4 tablespoons) of crazy cupcake batter in a bowl.
  • Next, depending on which flavor you'd like to make, mix in your add-ins.
  • Bake for 16 to 18 minutes then remove from the oven and allow to cool fully before frosting.
  • Enjoy!

Recipe Notes

1. This recipe makes 12 cupcakes with 1/4 c (4 Tbsp) of the base batter for each. The measurement for each flavor variation is for 1 cupcake. 
2. For peanut butter frosting: One tablespoon of peanut butter should flavor 4ozs/125g of buttercream frosting, but this depends on your taste. I suggest you taste as you go.
This amount should frost 4 cupcakes depending on how you use it.

I want to make the birthday cake cupcakes but if the recipe is to flavor one cupcake, to flavor all 12 I should need three teaspoons of vanilla and almond? Would that be right?

There is a mistake in ingredients quantity. If 1 cup is 225 g how 1 & 2/3 cups flour is also 225 g ?

Thank you for this recipe. I used it today in my homeschool baking class–since we are all home with our kids now. My girls each made their own flavor and they turned out great. Mint chocolate chip and Strawberry Lemonade.

Hi Gemma, this recipe saves so much time. Thank you! Could you kindly help with a coffee flavoured cupcake? Also, if I add vanilla essence to the basic batter, would this make plain vanilla cupcakes? And chocolate flavour?

I know I shared this on the Facebook page already. But Today at work, my boss was saying it should be cupcake Monday, after I made the chocolate peanutbutter cupcake and the cookies and cream cupcake for a friend for his birthday last week, and the extra I shared with my work colleagues and family, these cupcakes with the butter cream frosting were such a hit!

I’m now going to tackle the cookie recipe next.
