Grenade 12-Box Protein Bar - Birthday Cake
$59.90
Unit price perDescription
Twelve Birthday Cake bars to a box. It is the sweetest thing Grenade makes: a vanilla sponge centre with sprinkle pieces set into the coating, so it eats like a slice of frosted cake rather than a protein bar. Each one is 60g with around 20g of protein and typically 1 to 2g of sugar.
If this is the flavour you keep reaching for, the box is how you stop running out of it. Twelve sealed bars covers a couple of weeks of afternoons and still leaves a spare in the gym bag, without a top up shop every few days. The per bar cost sits on this page next to the box price so you can line it up against the singles.
Key Benefits
- 12 x 60g bars per box, 720g in total
- Around 20g protein per bar from a casein and whey blend
- Typically 1 to 2g sugar per bar
- Vanilla sponge centre with sprinkle pieces in the coating
- Individually sealed wrappers, so a box keeps in a cupboard or a desk drawer

Have one bar whenever you want the protein or the sweet hit, after training or mid afternoon. Store the box somewhere cool and out of the sun so the coating stays firm, and read the wrapper for that bar's exact panel because macros shift slightly between flavours.
People whose taste runs to the sweet, frosted end of the range and who get through more than a bar or two a week. A box also makes sense in a household where two of you are raiding the same snack cupboard. If you find Birthday Cake too sweet on its own, the Dark Choc Raspberry box sits at the opposite end of the scale.
How many bars are in the box?
Twelve 60g Birthday Cake bars, 720g of product in total.
Is the box better value than singles?
The per bar price is shown on this page beside the box price, so you can compare it against the single bar listing yourself.
Does it actually taste like cake?
It is vanilla sponge and frosting with sprinkle pieces rather than chocolate. It is the sweetest bar in the Grenade line up.
How should I store a full box?
Each bar is sealed on its own, so the box sits fine in a cupboard. Check the best before date printed on the wrapper.
