How to Make Kitchen Sink Cookies Recipe

Step 1: Preheat and Prepare

First things first: get your oven warmed up to 350°F. Line a cookie sheet with parchment paper or a silicone baking mat to keep your cookies from sticking and make cleanup easier. This simple prep step sets you up for baking success.

Step 2: Mix the Dry Ingredients

Grab a large mixing bowl and combine your oats, almond flour, protein powder, baking powder, and cinnamon. Mixing these dry ingredients well ensures that every cookie has a balanced flavor and texture, so don’t rush this step—it’s the foundation.

Step 3: Whisk the Wet Ingredients

In a separate bowl, whisk together melted coconut oil, egg, applesauce, honey, and vanilla extract. This combination brings moisture, sweetness, and binding elements that make your dough come together perfectly.

Step 4: Combine Wet and Dry

Pour the wet mixture into the dry ingredients and stir just until combined. Over-mixing can toughen cookies, so gentle folding is key to maintain tenderness.

Step 5: Add the Fun Stuff

Time to fold in the chocolate chips, M&Ms, and pretzel pieces. These extras create the signature “kitchen sink” feeling—like a delightful surprise in every bite. Mix just enough to distribute them evenly without breaking the chips and pretzels too much.

Step 6: Shape the Cookies

Using a cookie scoop or your hands, form balls of dough and place them on your prepared baking sheet. Give each cookie a gentle flattening so they bake evenly and develop a perfect golden edge.

Step 7: Optional Toppings

For an extra pop of color and chocolate goodness, press a few additional M&Ms onto the top of each cookie before sending them into the oven. It’s a small step that makes a big visual and taste impact.

Step 8: Bake to Perfection

Bake your cookies for 8-10 minutes, watching for golden edges. Remember, they will continue to set as they cool, so it’s better to take them out when they’re just barely golden rather than overbaking.

Step 9: Cool and Enjoy

Let the cookies rest on the baking sheet for a few minutes to firm up, then move them to a cooling rack. This ensures they finish setting nicely without losing their chewy center.

How to Serve Kitchen Sink Cookies Recipe

A stack of three oat cookies separated by light brown parchment paper sit on a white marbled surface. The top cookie has a small pretzel in the center, surrounded by colorful candy-coated chocolate pieces in blue, green, yellow, and orange, as well as dark chocolate chips mixed into the rough, textured cookie. Scattered around the cookies are small oats, broken pretzels, and some candy pieces. In the background, there is a white bowl filled with more cookies and a white container that seems to hold milk. photo taken with an iphone --ar 4:5 --v 7

Garnishes

Serve these cookies with a sprinkle of flaky sea salt on top for an elevated sweet-salty flavor profile. For a festive touch, add a dollop of whipped cream or a drizzle of melted peanut butter to the plate—both complement the diverse flavors beautifully.

Side Dishes

These cookies are delightfully versatile and pair wonderfully with a tall glass of cold milk, a rich cup of coffee, or a creamy latte. For a fun dessert platter, serve alongside fresh fruit or a scoop of vanilla ice cream to balance the textures and flavors.

Creative Ways to Present

For celebrations, stack the cookies into a rustic tower or arrange them in colorful layers alternating with mini cupcakes or brownies. You can also use them in an ice cream sandwich by splitting cookies and adding your favorite frozen treat in the middle—a total showstopper.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Kitchen Sink Cookies in an airtight container at room temperature for up to 5 days. This helps maintain that satisfying chewiness and crisp edges, so you can enjoy them fresh-tasting throughout the week.

Freezing

To make these treats last even longer, freeze the baked cookies in a sealed container or freezer bag. They’ll keep well for up to 3 months. Thaw at room temperature when you’re ready to indulge.

Reheating

If you love warm cookies, pop frozen or leftover cookies in a 300°F oven for about 5 minutes or microwave for 15-20 seconds. This revives their softness and melts the chocolate just right—almost like fresh from the oven.

FAQs

Can I substitute the almond flour?

Absolutely! If you’re allergic or prefer a different texture, all-purpose flour or oat flour can work, but expect a slightly different bite and flavor profile. Almond flour adds a lovely nuttiness that’s part of the cookie’s charm.

What if I don’t have vanilla protein powder?

You can omit it or replace with an equal amount of more almond flour or all-purpose flour. The protein powder adds a bit of nutrition and helps with texture but isn’t critical to the cookie’s success.

Are these cookies gluten-free?

Yes, as long as you use certified gluten-free oats and ensure the other ingredients are gluten-free. This recipe is naturally accommodating to gluten-free diets while remaining delicious.

Can I swap the honey for another sweetener?

Definitely! Maple syrup or agave nectar are excellent liquid sweetener alternatives that provide a slightly different flavor twist but maintain the cookie’s moisture and sweetness.

How do I make these cookies more chewy?

Be careful not to overbake—taking them out when the edges are just golden and the centers look slightly underdone yields the chewiest texture. Also, the applesauce helps retain moisture, which is key for chewiness.
