Ingredients
For these kitchen sink overnight oats, you’ll need the base from my cookie dough overnight oats recipe, plus a few delicious add-ins to take them over the top:
- Old-Fashioned Rolled Oats – The heart of any great overnight oat recipe.
- Protein Powder – Vanilla or chocolate will work here; I find vanilla gives it that extra cookie dough vibe.
- Milk of Choice – Almond, oat, or regular milk all work well.
- Greek Yogurt – Adds extra creaminess and a protein boost.
- Sweetener – A dash of maple syrup or honey for a touch of sweetness.
- Toffee Bits or Heath Bar Pieces – For those little caramelized, crunchy bites that make every spoonful exciting.
- Mini Pretzel Pieces – Crushed pretzels add a little saltiness and crunch for that kitchen sink feel.
- Mini Chocolate Chips – Because what’s a cookie-inspired treat without chocolate?
Instructions
1. Mix the Base Ingredients: In a bowl, combine oats, protein powder, milk or water, Greek yogurt, sugar-free pudding mix, vanilla bean paste or extract, almond extract, and sweetener. Stir well until everything is evenly mixed.
2. Add Half of the Mix-Ins: Gently fold in half of the mini chocolate chips, Heath toffee bits, and crushed pretzel pieces. This keeps them evenly distributed throughout the mixture.
3. Microwave the Mixture: Place the mixture in the microwave and heat for 45 seconds to 1 minute, they should rise a little!
4. Top with Remaining Mix-Ins: After microwaving, top the mixture with the remaining mini chocolate chips and Heath toffee bits. Cover the container and refrigerate overnight.
5. Serve & Enjoy: In the morning, skip stirring and add any additional crushed pretzels or extra toppings if desired.
Tips for the Best Overnight Oats
- Adjust Sweetness to Taste: Everyone’s sweet tooth is different! Feel free to add a little more (or less) maple syrup, stevia, honey, etc.
- Choose Your Protein Powder Wisely: The flavor of your protein powder can make a difference here. A vanilla powder keeps it classic, but a chocolate one adds a richer twist.
- Add a Little Extra Crunch in the Morning: If you love that crispiness, sprinkle on extra pretzel pieces or toffee bits right before you dig in.
Recipe Variations
1. Peanut Butter Lover’s Twist
Replace the crushed pretzels with crushed peanut butter pretzels or add a drizzle of natural peanut butter before serving. You can also mix peanut butter powder into the oat base for an extra boost of flavor.
2. Dark Chocolate Indulgence
Swap out the mini semisweet chocolate chips for dark chocolate chunks or cacao nibs for a richer taste. This pairs wonderfully with the salty pretzel topping.
3. Caramel Crunch
Replace the Heath toffee bits with caramel chips or drizzle sugar-free caramel sauce on top before serving. This adds a luscious sweetness to balance the salty notes.
4. Trail Mix Oats
Add a handful of dried fruit, like cranberries or raisins, and a sprinkle of chopped nuts (almonds, peanuts, or walnuts) for a chewy, crunchy texture.
5. Berry Bliss
Add fresh or frozen berries (blueberries or raspberries work great) to the oat base or as a topping to complement the sweet and salty combo.
6. Gluten-Free Option
Use certified gluten-free oats and gluten-free pretzels to make this recipe suitable for gluten-sensitive individuals.
7. Chocolate Toffee Delight
Double the toffee bits and add cocoa powder (1 tsp) to the oat base for a chocolatey, candy-inspired breakfast.

FAQ
Can I make these vegan?
Absolutely! Swap Greek yogurt for a plant-based yogurt and use a vegan protein powder. The rest of the ingredients are easy to adjust.
How long do these overnight oats keep?
These oats stay fresh for up to 4 days in the fridge, making them perfect for meal prep. Just be sure to keep them in an airtight container.
What can I use instead of pretzels?
If you’re not into pretzels, try crushed nuts, granola clusters, or even coconut flakes for that extra crunch.
Can I make this recipe ahead of time?
Yes! This recipe is perfect for meal prepping. Prepare up to three days in advance and store it in an airtight container in the refrigerator. Just add any delicate toppings, like pretzels, right before eating to keep them crunchy.
Can I skip the microwave step?
Microwaving helps soften the oats and meld the flavors, but if you prefer a no-cook method, you can skip it. Simply mix all the ingredients, layer in your toppings, and refrigerate overnight. The texture will be slightly different but still delicious.
How can I make this recipe even higher in protein?
Increase the amount of protein powder to a full serving, or add 1–2 tablespoons of powdered peanut butter or a dollop of Greek yogurt. You can also sprinkle on some chopped nuts for added protein and healthy fats.

You can reduce the amount of toffee bits and chocolate chips, or replace them with sugar-free versions. Adding extra crushed pretzels or fresh fruit is another lighter option for texture and flavor.

Leftovers can be stored in the fridge for up to 3 days, but the pretzels may lose their crunch over time. To enjoy the best texture, add fresh pretzels as a topping each day.
