My Stacked Brownie Donuts with Chocolate Truffle Filling are a delicious treat for anyone who loves chocolate. These donuts look as good as they taste. They have the rich color of classic brownies and are stacked in pairs and loaded with chocolate truffle filling. If that isn't enough chocolate for you, I've taken it one step further and drizzled even more chocolate on top!

When you bite into these donuts, the contrast of textures is a highlight – the firmer brownie against the softer filling. If you refrigerate them, they become even denser and fudgier, which some might prefer.
Flavor-wise, these donuts are a chocolate lover's treat. They're sweet, but not overly so, with a hint of vanilla and an optional touch of coffee. The dark chocolate filling adds a rich, chocolatey depth that goes well with the brownie base. The flavors blend nicely, creating a satisfying chocolate experience.

Ingredients In My Stacked Brownie Donuts
Brownie Donuts Ingredients:
- Unsalted Melted Butter: Acts as the fat component, providing moisture and richness to the brownie donuts. Unsalted butter is used to control the salt content in the recipe.
- White Sugar & Brown Sugar: These sugars sweeten the donuts. White sugar adds sweetness without affecting color, while brown sugar contributes to the moisture and gives a slight caramel-like flavor due to its molasses content.
- Vanilla Extract: Adds flavor depth and enhances the chocolate taste.
- Instant Coffee Granules: This is an optional ingredient that intensifies the chocolate flavor, making it richer and more robust.
- Large Eggs: Eggs are crucial for structure and binding. They also add moisture and richness.
- Cocoa Powder: Provides the chocolate flavor in the brownie donuts.
- All-Purpose Flour: Gives structure to the donuts, balancing out the moisture from the butter and eggs.

Chocolate Truffle Filling and Sauce Ingredients:
- Dark Chocolate: The primary ingredient for the truffle filling, offering a deep, rich chocolate flavor. The type of chocolate can vary according to personal preference.
- Cream: When heated and mixed with chocolate, it creates a smooth, rich ganache that serves as the filling and sauce.
- Sprinkles: These are optional and used for decorating the final product, adding a bit of color and texture.
The combination of these ingredients results in a dessert that's rich in chocolate flavor, with a moist and tender texture. The recipe balances sweetness with the deep flavors of cocoa and dark chocolate, while the addition of vanilla and optional coffee enhances the overall chocolate experience. The use of both white and brown sugars not only sweetens the donuts but also affects their texture and moisture content. The cream and chocolate come together to create a luxurious truffle filling that complements the brownie donuts.

How To Make Stacked Brownie Donuts
1. Preparing the Brownie Batter:
Mix the Wet Ingredients: Start by adding melted butter, white sugar, brown sugar, vanilla extract, and, if you're using it, instant coffee granules into a large bowl. Whisk these ingredients together until well combined.

Add the Eggs: Incorporate the eggs one at a time, making sure to whisk well after each addition.

Sift in the Dry Ingredients: Place a mesh strainer over your bowl and sift in the cocoa powder and all-purpose flour. This helps to prevent lumps and evenly distribute the dry ingredients.
Combine Everything: Mix everything together using a silicone spatula until you get a glossy brownie batter.

2. Baking the Donuts:
Preheat the Oven: Set your oven to 180°C (350°F).
Prepare the Donut Trays: Grease your donut trays to prevent sticking.
Pipe the Batter: Fill an 18" piping bag with the brownie batter and pipe it into the prepared donut trays.

Bake: Put the trays in the oven and bake for about 12-14 minutes. Be careful not to overbake to avoid drying out the brownies.
Cool: Let the donuts cool in the pan for 10 minutes, then transfer them to a wire rack to cool completely.

3. Making the Chocolate Truffle Filling and Sauce:
Melt Chocolate with Cream: Place the dark chocolate in a heatproof bowl and add hot cream. Mix them well into a smooth, glossy mixture.

Chill the Mixture: Refrigerate the chocolate mixture, stirring every 10 minutes, until it thickens enough to be piped.

4. Assembling the Stacked Donuts:
Fill Piping Bag: Once the chocolate truffle filling is ready, transfer it to an 18" piping bag fitted with a 1M piping tip.
Stack and Fill: Pipe a double layer of truffle ganache onto the flat side of one donut, then place another donut on top, flat side down. Repeat this for all your donuts.

Decorate: Use the remaining chocolate truffle filling to add a decorative touch. You can heat it slightly if needed and drizzle it over the stacked donuts.

5. Serving:
Enjoy Fresh or Refrigerated: These donuts can be eaten right away or stored in the refrigerator. If left until the next day, they'll develop a denser, fudgier texture.
My Top Tip
The most important tip for making the Stacked Brownie Donuts with Chocolate Truffle Filling is to be mindful of the baking time for the brownie donuts. Unlike regular donuts, brownie donuts have a denser, fudgier texture that's more like traditional brownies. Therefore, it's crucial to avoid overbaking them. Overbaked brownie donuts can become dry and lose their characteristic moist and tender texture.
Here's how to manage this:
Keep a Close Eye on the Timer: Bake the donuts for 12-14 minutes at 180°C (350°F), but start checking them around the 10-minute mark. Ovens can vary, so it's important to adjust the timing according to how your oven performs.
Test for Doneness: You can use a toothpick to check if the donuts are done. Insert it into a donut; it should come out with a few moist crumbs, but not wet batter. If it does, they're ready.
Some Delicious Variations
- Mint Chocolate: Add a few drops of peppermint extract to the chocolate truffle filling for a refreshing mint-chocolate twist.
- Orange Zest: Incorporate orange zest into the chocolate truffle for a citrusy note.
- Raspberry Puree: Swirl in some raspberry puree for a fruity, tangy contrast.
- Chopped Nuts: Sprinkle chopped walnuts, almonds, or hazelnuts on top or fold them into the brownie batter for added crunch.
- Nut Butter Swirl: Marble the top of the donuts with peanut butter or almond butter before baking for a nutty flavor.
- Cinnamon or Chili: Add a pinch of cinnamon or chili powder to the brownie batter for a warm, spicy kick.
- White Chocolate Filling: Use white chocolate for the truffle filling for a milder, creamier taste.
- Salted Caramel: Drizzle salted caramel over the finished donuts or mix it into the chocolate filling.
- Sea Salt: A light sprinkle of sea salt on top can balance the sweetness and add sophistication.
- Toasted Coconut: Top the donuts with toasted coconut flakes for a tropical twist.
- Gluten-Free Flour: Use a gluten-free flour blend for those with dietary restrictions.
- Liqueur-Infused Filling: Add a splash of your favorite liqueur (like Baileys, Kahlúa, or Amaretto) to the chocolate truffle for an adult version.
