These Coffee Cake Overnight Oats are an easy breakfast that tastes like dessert! With oats, yogurt, and a touch of coffee flavor, they’ll give you a yummy start to your day.

Key Ingredients & Substitutions

Rolled Oats: Use rolled oats for the best texture, but quick oats can work in a pinch, yielding a creamier consistency. Steel-cut oats need longer soaking time, so I wouldn’t recommend them here.

Milk: You can use any type of milk you like—almond, soy, or oat milk are great plant-based options. If you’re looking for creaminess, go for whole milk or even coconut milk!

Greek Yogurt: This adds protein and creaminess. If you’re avoiding dairy, look for a plant-based yogurt. Coconut yogurt or almond-based yogurt work well.

Maple Syrup: If you’re out of maple syrup, honey or agave nectar can be used as sweeteners. You can even adjust the sweetness to your liking!

Pecans: If you don’t have pecans, walnuts or almonds can be nice substitutes. You could also skip nuts if you want a nut-free option or if allergies are a concern.

How Do You Get the Perfect Streusel Topping?

The streusel topping adds a great crunch, but getting it just right is essential! Here’s how to do it:

  • Use cold ingredients: Keep your butter or coconut oil chilled before mixing. This helps create crumbly bits.
  • Mix well: Combine brown sugar, flour, melted butter or oil, and a pinch of salt. It should be crumbly, not too wet.
  • Incorporate nuts: Adding chopped pecans offers extra flavor and crunch. Just make sure not to overmix, or you’ll lose the crumbly texture!

Feel free to make this topping ahead and store it in the fridge. It’s a great way to have a quick breakfast ready to go!

How to Make Coffee Cake Overnight Oats

Ingredients You’ll Need:

  • 1/2 cup rolled oats
  • 1/2 cup milk (dairy or plant-based)
  • 1/4 cup plain Greek yogurt
  • 1 tbsp brewed coffee (cooled)
  • 1 tbsp maple syrup or honey
  • 1/2 tsp vanilla extract
  • 1/4 tsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 1 tbsp brown sugar (for streusel topping)
  • 1 tbsp flour (all-purpose or oat flour, for streusel topping)
  • 1 tbsp butter or coconut oil, melted (for streusel topping)
  • Pinch of salt (for streusel topping)
  • 3-4 pecan halves (plus extra for garnish)
  • Peanut butter or almond butter drizzle (optional)

How Much Time Will You Need?

This recipe is quick to prepare, taking about 10-15 minutes to combine ingredients. Then, let it chill in the fridge overnight for at least 6 hours. This makes a fabulous breakfast ready to grab as you start your day!

Step-by-Step Instructions:

1. Mix the Base:

In a medium bowl or jar, combine the rolled oats, milk, Greek yogurt, cooled brewed coffee, maple syrup or honey, vanilla extract, ground cinnamon, and ground nutmeg. Stir everything well until it’s nicely mixed. It will look a bit creamy!

2. Refrigerate:

Cover the bowl or jar and place it in the fridge. Let the mixture chill overnight or for a minimum of 6 hours. This allows the oats to absorb the liquid and soften, making them delicious and ready to eat!

3. Make the Streusel Topping:

While the oats are chilling, you can prepare the streusel topping. In a small bowl, mix together the brown sugar, flour, melted butter or coconut oil, and a pinch of salt until it looks crumbly. Then, stir in the chopped pecans. This will add a nice crunch!

4. Assemble the Oats:

When you’re ready to serve, give the oats a good stir. Spoon half of the oats into a serving glass or bowl. Spread a layer of the streusel on top and gently press it down.

5. Finish and Garnish:

Top it off with the remaining oats and sprinkle extra streusel on top. Add whole pecans for garnish. If you like, drizzle some peanut butter or almond butter over everything for a delicious finishing touch.

6. Enjoy!

Dig in right away or let it chill for a few more minutes if you’d like it even colder. This cozy breakfast is sure to give you the yummy flavor of coffee cake in every bite!

Can I Use Instant Oats Instead of Rolled Oats?

Yes, you can use instant oats, but keep in mind they will absorb liquid more quickly and result in a creamier texture. Reduce the soaking time to about 4 hours or enjoy them right after mixing!

How Can I Make This Recipe Vegan?

To make this recipe vegan, substitute the Greek yogurt with a dairy-free yogurt, such as coconut or almond yogurt, and use maple syrup as the sweetener, ensuring all other ingredients are plant-based.

Can I Store Leftover Oats?

Yes! Store any leftovers in an airtight container in the refrigerator for up to 3 days. Just give them a good stir before eating, and if they seem a bit thick, add a splash of milk to loosen them up.

What Other Toppings Can I Use?

Feel free to get creative with toppings! You can add fresh fruits like bananas or berries, a dollop of nut butter, or even a sprinkle of chocolate chips for extra sweetness!
