64 Recipes Using Cake Mix That Are Easy and Creative

From caramel cookies to gooey bars and apple pie cupcakes, these easy recipes using cake mix turn a basic boxed mix into something unforgettable.

Great desserts don’t always start from scratch—sometimes they start with cake mix. This pantry staple does more than save time, as it’s the base for cookies with crisp edges and fruit-filled trifles. These recipes using cake mix show how a simple boxed mix can help create something that feels bakery-made, especially with add-ins like pudding mix, soda or citrus zest. Whether baking for a party or looking for easy no-bake desserts, cake mix makes it easy to whip up treats that feel both clever and comforting.

We chose recipes that show off cake mix’s range, from soft muffins to pancakes and cinnamon rolls. These easy recipes with cake mix lean into comfort—like rhubarb custard cake with its gooey layers or pumpkin muffins that stay soft and spiced. Others get creative—strawberry brownies bake up with a chewy texture, while funfetti pancakes bring birthday-cake flavor to the breakfast table. You’ll also find red velvet cinnamon rolls with tender swirls or lemon snowflakes that disappear in one bite. When creamy meets crisp in chocolate chip cheesecake bars, it’s a reminder of how satisfying quick dessert recipes can be with just a few clever upgrades.

With a few boxed cake mix hacks, these recipes offer more than convenience. Sour cream adds richness, while egg whites or soda lighten the crumb, and a handful of chocolate chips can completely shift the texture. These recipes capture everything we love about boxed cake mix—they’re simple to make, endlessly adaptable and full of homemade baking.

Recipes Using Cake Mix FAQ

Can I use cake mix to make cookies?

Yes, cake mix is a handy shortcut for soft, chewy cookies with crisp edges. Mix one box of cake mix with two eggs and about 1/2 cup of oil or melted butter to form a soft dough. The texture is lighter than basic cookie dough but holds up well with add-ins like chopped candy, crushed pretzels or toffee bits. For neater edges and less spread, chill the dough for 30 minutes before baking. These cookies are great for bake sales, lunchboxes or quick weeknight treats.

What are some no-bake recipes with cake mix?

You can use cake mix to make easy no-bake treats like cake batter truffles, dessert dips and layered bars. Just heat the dry mix first, then blend it with creamy ingredients like whipped topping, sweetened condensed milk or cream cheese. The result is soft, sweet and full of cake flavor—perfect for warm days or when you want something quick without turning on the oven. You can shape the mixture into bite-sized truffles, spread it into bars, or turn it into a dip with cookies or fruit for scooping. These desserts store well in the fridge and are easy to customize with extracts, crushed candy or a swirl of jam.

How should I store desserts made from cake mix?

Most cake mix desserts keep well at room temperature for a couple of days if stored in an airtight container. Treats with perishable fillings like cream cheese, whipped topping or fresh fruit should be refrigerated and are best eaten within five days. Bars and cakes with no frosting also freeze well when wrapped tightly, using the same approach you would for freezing cakes and cupcakes. If you’re stacking cookies or bars, add parchment between layers to prevent sticking.
