Breakfast Sludge

PIn it

Introduction

This is a no-fuss morning drink that delivers coffee, chocolate, and spice in one mug—you’re essentially brewing a flavored granola slurry with instant powders and milk. It takes about 5 minutes from kettle to cup and works as a grab-and-go breakfast or a warming afternoon pick-me-up when you need something more substantial than plain coffee.

Recipe Details

• Prep Time: 3 minutes
• Cook Time: 2 minutes
• Total Time: 5 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

1. Put water on to boil.
2. 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.
3. Add the instant coffee, chai, sugar, and hot chocolate powder to the cup.
4. Add cinnamon to taste.
5. Pour in enough boiling water to fill the cup.
6. Stir vigorously until everything is mixed and the mixture has a dark brown appearance.
7. Add milk to taste.

Variations

Use loose leaf tea instead of a teabag. This gives you more control over strength and eliminates paper flavor; steep for 30 seconds before adding other powders to extract the tea fully.

Swap the granola bar for quick oats. Use 2–3 tablespoons of rolled oats instead; they’ll soften just as quickly and create the same body without the binder and sweetness of a prepared bar.

Skip the hot chocolate powder and double the cinnamon. This shifts the drink toward spiced coffee and reduces sweetness if you prefer a less dessert-like breakfast drink.

Use cold milk and skip the boiling water step. Stir all powders and granola into cold milk in a blender for 20 seconds to create a chilled breakfast smoothie instead.

Add a pinch of salt. A tiny pinch balances the sweetness and rounds out the chocolate and coffee notes.

Tips for Success

Break the granola bar into very small pieces before adding hot water. Larger chunks won’t soften evenly and will leave gritty bits at the bottom; aim for oatmeal-sized crumbles to ensure everything dissolves or softens uniformly.

Stir vigorously for a full 10–15 seconds. The hot chocolate powder and instant coffee can clump if they hit water too quickly; vigorous stirring breaks these up and prevents a gritty mouthfeel.

Add milk after everything else is mixed. This prevents the milk from cooling the mug too much before the powders fully hydrate, and it lets you control the final texture and strength to your taste.

Check the color as you stir. The mixture should turn dark brown once fully mixed; if it stays light or mottled, stir longer or add a splash more water to help the powders dissolve.

Storage and Reheating

FAQ

Can I use a different type of granola bar? Yes—chocolate, oat, or nut-based bars all work; however, flavored bars (like strawberry or coconut) will change the overall taste profile noticeably. Stick with neutral or chocolate-based bars if you want the coffee and cinnamon to remain the dominant flavors.

What if I don’t have instant coffee powder? Use 1 teaspoon of finely ground espresso powder or dissolve 1 teaspoon of instant espresso in a small amount of boiling water before adding to the mug. Cold brewed coffee concentrate (1–2 teaspoons) also works if you have it on hand.

Can I make this without milk? Yes. The drink works with just water and boiling liquid, though it will be thinner and less creamy. If you want creaminess without dairy milk, use a plant-based milk (oat, almond, or soy) instead.

How do I make this less sweet? Reduce the sugar to 1 teaspoon, skip the granola bar and use plain oats, or omit the hot chocolate powder entirely and add only cinnamon for warmth. You can always taste and adjust before adding milk.
