Ingredients


- Butter: I use organic salted butter that's melted for extra fudgy brownies.
- Dutch Cocoa Powder: I'm using NuNaturals Organic Dutch Cocoa Powder for a rich chocolate flavor. This is my go-to cocoa powder for baking and what we used at my bakery for over a decade! Their flavor and quality is unmatched. Use code MIMI for 10% off your order.
- Pumpkin: Organic pumpkin puree acts as an egg replacer, making these brownies extra moist. It also provides flavor! Also, try Soft Baked Pumpkin Spice Cranberry Sandwich Cookies or Pumpkin Spice Pop Tarts With Pie Crust for another delicious eggless pumpkin dessert.
- Chocolate Oat Milk: I also use Willa's Organic Chocolate Oat Milk as an egg replacer too! This provides a creamy texture with added chocolate flavor!
- Coffee: I use Peace Coffee inside the brownies and in the glaze for coffee flavor in every bite!
- Collagen: My favorite organic collagen is NuNaturals Grassfed Organic Collagen, which is what gives these protein brownies 9 grams of protein in each brownie! Use code MIMI for 10% off your order!

Baker's Tips for Pumpkin Spice Latte Protein Brownies
- Always use a digital food scale for the best results!
- You don't need a hand mixer, you can make this with just a whisk or spatula too, it's very flexible.
- Because these are eggless brownies, there's no worry of under baking them if you like really gooey brownies you can bake on the lower end of the time frame.
- The glaze is optional, but it also provides much more coffee flavor.
- Be sure to store in an airtight container so they stay fresh.
- You can also freeze these by wrapping in plastic and storing in an airtight container or zip bag in the freezer. Just thaw and enjoy!
How to Make Pumpkin Spice Latte Protein Brownies

- Preheat the oven to 350°F. Line an 8×8-inch baking pan with parchment paper. To make the brownies: In a large mixing bowl, melt the mini dark chocolate chips doing 30 second intervals in the microwave, stirring between each one.

- Add the cane sugar, cocoa powder, chocolate oat milk, coffee, pumpkin puree and melted butter to the mixing bowl.

- Mix, using a hand mixer (or using a whisk) until completely combined.

- Add in the all purpose flour, collagen, baking powder, salt, and pumpkin spice.

- Mix on low until combined into a smooth brownie batter.

- Transfer the brownie batter to the prepared baking pan and spread it out evenly.

- Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. Allow the brownies to cool completely in the baking pan.

- To make the glaze: In a medium mixing bowl, add the powdered sugar and coffee.

- Whisk together until you have a smooth glaze. You can use more or less coffee, depending on the consistency of glaze you like (more for thinner, less for thicker).

- Remove the brownies from the pan and drizzle the glaze on top. Cut into 9 squares.

Recipe FAQ's
While traditional brownies like my Sourdough Chocolate Chip Brownies only have 3 grams of protein per brownie, these Pumpkin Spice Latte Protein Brownies have 9 grams per brownie! That's like eating a protein bar, but in brownie form!
While this recipe for Pumpkin Spice Latte Protein Brownies has 9 grams of protein per brownie from grassfed organic collagen, it is still a brownie! There's still sugar, butter, and flour. So, while this brownie recipe does have as much protein as a protein bar, it's still a brownie. You do the math.
Simply leave the collagen out or add in your favorite protein powder in its place. Either works.
