Cereal Milk Frappé (Real Steeping Technique)

Our Cereal Milk Latte covers the full steeping technique — corn flakes steeped in warm milk, strained out, treated like a tea bag rather than an ingredient that ends up in the cup. This is the same cereal milk, blended into a frappé with espresso and ice instead of steamed and poured hot.

Make the Cereal Milk First (Small Batch)

Steep 3 cups of corn flakes in 3 cups of warmed whole milk for 15-20 minutes, then strain, pressing the cereal to extract all the liquid. This yields about 20oz of usable cereal milk — enough for roughly 2.5 servings across the latte and this frappé combined. It keeps about 2 days in the fridge, shorter than this site’s cooked syrups.

Building the Frappé

1. Pull a double shot of espresso.
2. Add the espresso, 4oz of the strained cereal milk, and 1.5 cups of ice to a blender.
3. Blend on high for 30-45 seconds until smooth and slushy.
4. Pour into a 16oz glass and serve immediately with a straw.

Specialty/trendy café blended cereal milk drink (grande)~$6.95

Home cereal milk frappé (espresso, cereal milk, ice)~$0.85

Savings per drink$6.10

Assumptions: a 3-cup corn flakes/3-cup whole milk batch (about $3.11, yielding ~2.5 servings across both formats), grande-size blended drink, and a representative specialty-café price for this trendy, specialty-shop-only flavor. At 5 of these a week over the site’s standard 48-week year, that’s roughly $1,464/year back in your pocket versus the café version.

Swaps & Notes

• Want it a little sweeter? Add 1/2 tbsp Vanilla Syrup to the blender along with the other ingredients — the plain version above leans on the cereal’s own subtle sweetness alone.
• No blender? The Cereal Milk Latte uses the same cereal milk poured hot over espresso instead — a completely valid version, just a different format.
• Cereal milk keeps only about 2 days in the fridge — plan a batch size around using it across both the latte and this frappé within that window rather than making a large batch and letting it sit.

FAQ

Is this the same cereal milk as the latte version?

Yes — one batch (3 cups corn flakes steeped in 3 cups milk) covers both the Cereal Milk Latte and this frappé, split across roughly 2.5 servings total.

Does the frappé actually contain cereal pieces?

No — same as the latte, the cereal is strained out completely after steeping. What’s left is milk carrying the cereal’s flavor, blended smooth with espresso and ice, not a gritty or chunky texture.

Can I use a different milk for the steeping step?

Whole milk is the default because its fat content carries the cereal’s flavor best, but oat or 2% milk both work — expect a slightly less rich result with either.
