KODIAK MUG CAKE
This Kodiak mug cake turns a scoop of Kodiak Cakes mix and a spoon of peanut butter into a warm, tender, single-serve cake in about a minute. It is the rare quick treat that actually fills you up, thanks to the whole-grain, high-protein mix doing the heavy lifting.
Why you'll love this
- One mug, one spoon, ready in roughly a minute with almost no cleanup
- Genuinely filling and high in protein from the Kodiak mix plus peanut butter
- A thick, cookie-dough-like batter that bakes up soft rather than spongy
- Endlessly toppable: honey, banana, berries or a dusting of cinnamon
Key ingredients & swaps
- Kodiak Cakes mix — the whole-grain, protein-packed base that does all the work; measure half a cup and don't pack it, since extra mix is the fastest route to a dry, dense cake
- Peanut butter — adds richness, healthy fat and staying power in place of butter; warm it for a few seconds if it's stiff so it stirs in smoothly, or swap almond butter
- Water or milk — loosens the batter to the right thickness; add it a splash at a time, and use milk for a little extra protein and a softer crumb
- Honey (optional) — a finishing drizzle for sweetness, since the mix itself is only lightly sweet; maple syrup works just as well
How to make it (step by step)
-
1
Pick the right mug
Reach for a wide, microwave-safe mug rather than a tall narrow one so the batter cooks evenly and has room to rise without climbing over the rim.
-
2
Stir in the peanut butter
Add half a cup of Kodiak mix and the peanut butter to the mug and stir to combine; it will look thick and crumbly at this stage, which is exactly right.
-
3
Loosen the batter slowly
Add water or milk a little at a time, stirring after each splash, until the batter is thick like cookie dough and just smooth. Stop as soon as it comes together; overmixing develops the gluten and turns the cake rubbery.
-
4
Microwave in one short burst
Microwave on high for about 1 minute. The top should look set and spring back lightly; if you still see wet, shiny spots larger than a dime, it needs a few more seconds.
-
5
Rest, then finish if needed
Let it sit 30 seconds; carryover heat keeps cooking the centre. If it's still gooey underneath, microwave in 15 to 20 second bursts, checking each time so it doesn't overcook and dry out.
-
6
Top and eat warm
Finish with a drizzle of honey, sliced banana, berries or a pinch of cinnamon and eat straight from the mug while it's warm and at its softest.
Pro tips
- Overcooking is the number-one cause of a dry, rubbery mug cake; go in short bursts and pull it the moment the centre is just set.
- Add liquid gradually, not all at once: too much makes it gummy, too little makes it dry. You're aiming for thick cookie-dough batter.
- Stir just until combined; the more you beat the batter, the tougher the crumb.
Variations
- Chocolate: stir a teaspoon of cocoa powder into the mix, or press in a few chocolate chips before microwaving.
- Higher protein: mix with milk instead of water, or stir in a tablespoon of vanilla protein powder plus an extra splash of liquid.
- Banana bread style: mash in a few slices of ripe banana and a pinch of cinnamon for a softer, fruitier cake.
Storage & freezing
Mug cakes are best eaten fresh and warm, but you can cover and refrigerate it for up to a day and reheat for 10 to 15 seconds, accepting a slightly firmer crumb.

Frequently asked questions
Why did my Kodiak mug cake turn out rubbery?
Rubberiness comes from overcooking or overmixing. The high-protein mix toughens fast, so stir only until combined and microwave in short bursts, stopping as soon as the centre springs back.
Why is my mug cake dry?
Usually too much mix or too long in the microwave. Don't pack the half cup of Kodiak mix, add liquid until the batter is just smooth, and pull the cake the moment it's set rather than cooking it through fully.
Can I use water instead of milk?
Yes. Water works perfectly and keeps it simple; milk just adds a little extra protein and a slightly softer, richer crumb. Use whichever you have.
Do I need an egg?
No. This version relies on the Kodiak mix and peanut butter to bind, so no egg is needed. If you add one for extra protein, add a touch more liquid and expect a more custardy texture.
What size mug should I use?
A wide mug of at least 12 ounces. The batter puffs as it cooks, and a wide, roomy mug helps it cook evenly and stops it overflowing.
Can I make it without peanut butter?
Yes. Swap in almond butter, sunflower seed butter or a tablespoon of melted butter or oil; you just want some fat to keep the cake moist and rich.
Can I bake it in the oven instead?
You can. Pour the batter into a small oven-safe ramekin and bake at around 350F (175C) for 12 to 15 minutes, until a toothpick comes out clean.
