Forget what you think you know about Rice Krispies treats — we’re keeping the snap, crackle, and pop, but giving them a fun cake-batter makeover. These Cake Batter Rice Krispies Treats use sweetened condensed milk, boxed cake mix, and a trio of extracts to create a rich, gooey bar studded with colorful sprinkles. The result is nostalgic, indulgent, and soft longer than the classic version.
Sweetened condensed milk is the game-changer here. It adds creaminess and extra chew, helping the bars stay soft for days. Paired with melted butter and plenty of marshmallows, it forms a velvety base that holds the Rice Krispies and cake-flavored mix together.
To create that unmistakable cake-batter flavor without baking a cake, this recipe combines boxed cake mix with multiple extracts. Warming the dry cake mix briefly makes it safe to eat and helps enhance its flavor. Clear vanilla keeps the color bright, while pure vanilla and a touch of almond extract round out the classic birthday-cake profile.
Here’s how the elements come together:
- Heat the cake mix briefly to treat the raw flour and intensify flavor.
- Melt butter with sweetened condensed milk to form a rich, creamy base.
- Add marshmallows and stir until fully melted for that signature gooey texture.
- Blend in clear vanilla, pure vanilla, and almond extracts for depth and authenticity.
- Coat the Rice Krispies thoroughly in the warm marshmallow mixture, working quickly to press into the prepared pan.
- Finish with lots of sprinkles for color and a bit of crunch.
These treats are flexible and forgiving. If you want extra gooey bars, increase the marshmallow-to-butter ratio slightly. If you need to work in batches because of bowl size, keep the marshmallow mixture warm over low heat while you coat the cereal. Press the mixture evenly into a well-buttered 9 x 13-inch pan and top generously with sprinkles before cutting.
These Cake Batter Rice Krispies Treats are great for parties, bake sales, school events, or just an everyday sweet craving. They capture the playful spirit of childhood while delivering a richer, more indulgent texture than standard cereal bars.
Ingredients
- 1 to 1/4 cup boxed cake mix (white or Funfetti)
- 12 tablespoons (170 grams) butter
- 2/3 cup (192 grams) sweetened condensed milk
- 12 cups (about 516 grams / 18 ounces) mini marshmallows
- 1 to 1/2 teaspoons clear vanilla extract
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon almond extract
- 10 cups (about 280 grams / 10 ounces) Rice Krispies cereal
- 1 cup sprinkles (your choice)
Instructions
- Place the cake mix in a microwave-safe bowl and heat in 30-second intervals, stirring between each, until the mixture reaches 165°F (this treats the raw flour and makes it safe to eat).
- Generously butter a 9 x 13-inch baking pan and set aside.
- In a large pot or Dutch oven, melt the butter over medium heat. Whisk in the sweetened condensed milk and the warmed cake mix until smooth. Add the marshmallows and stir frequently until completely melted and glossy.
- Transfer the Rice Krispies to the largest bowl you have. Pour the warm marshmallow mixture over the cereal and fold with a rubber spatula until every piece is coated. Work quickly: press the mixture into the prepared pan using a spatula or buttered fingers to create an even layer. Immediately sprinkle the top with sprinkles, press lightly, then allow to set before cutting into squares.
Notes
Because of the sweetened condensed milk, these treats remain soft for several days when stored in an airtight container.
