Microwave PB and Banana French Toast Cup
By the QuiteRecipes team (Jamy & Kaïna) | Food Service Professional, Early Childhood Expert & Parents
A warm, custardy French toast cup swirled with peanut butter and banana — cinnamon-sweet, protein-boosted, and made in minutes in the microwave.
French toast in a mug sounds like a fantasy, but this peanut butter and banana cup turns it real in about seven minutes. Cubed bread soaks up a cinnamon-egg custard, peanut butter melts through in warm pockets, and sliced banana sweetens every spoonful as the whole thing sets in the microwave. It's custardy, cozy, and genuinely satisfying — like a tiny brunch made for one. We love it on mornings that call for something warm, sweet, and a little special with no skillet to wash.

👨🍳 Instructions
**In a large microwave-safe mug**, whisk the egg, milk, syrup, vanilla, cinnamon, and salt.
**Stir in the cubed bread** and push it down to soak; fold in the peanut butter and half the banana.

**Top with the remaining banana and a drizzle of peanut butter**, and eat warm.
⚠️ Common Mistakes
- ✕
Soggy pockets from uneven custard; coat the cubes fully.
- ✕
Overcooked, rubbery cup — pull it at a just-set center.
- ✕
Bland base — the cinnamon and vanilla carry the flavor.
- ✕
Boil-over from too small a mug; always go large.
🔄 Variations
Chocolate-dream: add chocolate chips with the banana.
Berry swirl: a spoon of jam or fresh berries instead of PB.
French-toast-bee: use brioche for a richer, more indulgent cup.
Protein boost: a scoop of vanilla protein stirred into the custard.
🧊 Storage
- 📦
Best fresh and warm; reheating once gently is fine.
💡 Chef Tips
Stale bread soaks best — day-old cubes drink up the custard.
Push the bread down so every cube gets coated evenly.
Peanut butter in dollops melts into warm, surprising pockets.
Rest before eating so the custard sets up properly.
