Introduction
This mug recipe turns a granola bar or oatmeal/granola into a warm, thick drink with instant coffee, chai, hot chocolate, and a pinch of cinnamon. You break the granola down to oatmeal-size pieces, stir in boiling water until the mixture turns dark brown, then finish with milk. It fits as a fast breakfast or an afternoon pick-me-up when you want something more filling than a standard hot drink.
Recipe Details

- Cook Time: 5 minutes
- Total Time: 10 minutes
- Servings: 1
Ingredients
- Water
- 1 granola bar or oatmeal/granola
- 1 scoop of instant coffee powder
- 1 teabag or 1 scoop of chai powder
- 1 tablespoon of sugar
- 1 scoop of hot chocolate powder
- 1 pinch of cinnamon powder
- Milk
Instructions
- Put water on to boil.
- Break up the granola bar into a mug. You will want to ensure that it is very well ground up. The pieces of the granola bar should be about the size of pieces of oatmeal.
- Add the instant coffee, chai, sugar, and hot chocolate powder to the cup.
- Add cinnamon to taste.
- Pour in enough boiling water to fill the cup.
- Stir vigorously until everything is mixed and the mixture has a dark brown appearance.
- Add milk to taste.
Variations
- Change 1 granola bar to oatmeal/granola if you want a less sweet, more porridge-like texture.
- Use 1 scoop of chai powder instead of 1 teabag for stronger spice flavor and a slightly fuller body.
- Skip the instant coffee powder if you want the drink to lean more toward chai cocoa and contain less caffeine.
- Change Milk to oat milk or soy milk if you want a dairy-free finish with a slightly lighter texture.
- Reduce the 1 tablespoon of sugar if your granola bar and hot chocolate powder are already sweet; the final cup will taste less dessert-like.
Tips for Success
- Grind the granola bar down to oatmeal-size pieces, or it will stay chunky instead of blending into the drink.
- Add the boiling water while the dry ingredients are already in the mug so the instant coffee and hot chocolate powder dissolve more easily.
- Add Milk at the end, not before the boiling water, so the heat stays high enough to mix everything smoothly.
- If you use a teabag, let it sit in the mug for a minute or two before your final stir if you want a stronger chai note.
Storage and Reheating
You will get the best texture if you drink this right after making it. If you need to hold it, store it in a sealed jar or covered mug in the fridge for up to 1 day.
FAQ
Can you use plain oats instead of a granola bar?
Yes. Plain oats make the drink less sweet and more like a thin oatmeal, so you may want extra stirring to fully soften them.
What if you only have a teabag and not chai powder?
You can use the teabag as written. Let it steep briefly in the hot mixture if you want more spice before removing it.
Why did the mixture turn lumpy?
That usually means the granola pieces were too large or the powders were not stirred enough once the boiling water went in. Break the granola finer and stir hard until the color is evenly dark brown.
Can you make it without dairy milk?
Yes. Oat milk and soy milk both work well and keep the drink creamy enough to balance the coffee and cocoa.
