Ingredients

  • Protein powder: for softness and a boost of protein try to pick one you love the flavor of since it is the main base
  • Oat flour: gives that classic cinnamon roll texture or swap for almond flour for gluten free
  • Baking powder: makes the mug cake rise and stay fluffy always check your baking powder is fresh
  • Ground cinnamon: for that essential warmth and spice pick a good quality cinnamon for more aroma
  • Salt: to balance the sweetness and round out flavors
  • Egg: for binding and extra protein always use the freshest large egg for best texture
  • Almond milk or milk of choice: for moisture unsweetened keeps things balanced
  • Maple syrup or honey: to sweeten gently and keep things moist choose pure maple syrup for the best flavor
  • Vanilla extract: for bakery worthy depth real vanilla gives better results than imitation
  • Coconut oil or melted butter (in the swirl): for richness and a gooey bite
  • Brown sugar or coconut sugar (in the swirl): for that signature cinnamon swirl choose one with deep molasses notes if possible
  • Greek yogurt and cream cheese (optional frosting): for tang and creaminess use full fat for a richer topping

My favorite part is the swirl of cinnamon sugar melting right into the cake It reminds me of Sunday mornings when my family would bake together We might not always have time now for traditional cinnamon rolls but this mug cake gives us all the cozy feelings in just a few minutes

Storage Tips

If you want to prep ahead you can mix the dry ingredients and keep in a sealed container Then just add the wet ingredients and swirl right before microwaving Leftover cake is best reheated gently with a splash of milk as it can dry out if left too long

Ingredient Substitutions

For dairy free swap in any plant based milk and dairy free yogurt or cream cheese Try pea or soy protein instead of whey if needed If you want to lower the sugar use a zero calorie sweetener just remember it may affect the texture

Serving Suggestions

This mug cake is delicious with a sprinkle of extra cinnamon or chopped nuts on top For a true treat swirl a little extra syrup over the frosting or add a handful of berries for a fresh bite Sometimes I add a spoonful of nut butter for even more staying power

Cultural Twists

Cinnamon rolls are beloved for their warmth and sweet aroma This mug cake brings the nostalgic flavor in a much faster form I sometimes sprinkle cardamom or a hint of nutmeg to echo flavors from northern European baking traditions

Seasonal Adaptations

In colder months try adding pumpkin spice or apple pie spice and swapping in applesauce for some of the almond milk In summer swirl in a spoonful of berry jam for a fruity take or top with fresh peaches for a southern twist
