Microwave Tips
Every microwave heats differently! Start with 70 seconds and add more time if needed. Your mug cake is ready when the top looks just set but still has a tiny bit of shine – this keeps it super moist and gooey inside.
Let it sit in the microwave for that extra minute – it might seem like forever when you’re craving dessert, but this helps everything settle into cake perfection!
Quick Substitutions
No peanut butter? Any nut butter works great here! Try almond butter for a nutty twist, or cookie butter for something totally different. Out of regular milk? Plant-based milk works just fine. Want it extra rich? Use melted butter instead of oil.
For the chocolate chips, dark, milk, or white chocolate all taste amazing – or break up your favorite candy bar!
Make It Extra Special
Add a scoop of vanilla ice cream right on top while it’s warm – it melts into all the nooks and makes everything extra yummy! Love it extra chocolatey? Drizzle some chocolate sauce on top. For a fun twist, sprinkle crushed peanuts or cookie crumbs over everything. Want it fancy? Add a dollop of whipped cream and a few extra chocolate chips on top!
Storage Notes
This mug cake tastes best fresh and warm, right from the microwave. It’s made for eating right away, so try to finish it while it’s still warm and gooey. If you make too much, cover your mug with plastic wrap and eat it within a few hours – just know it might not be as soft as when it’s fresh.
