How to Make Monster Brownie Pizza Recipe
Making this dessert is a simple process that starts with a standard brownie base and upgrades it with exciting textures and toppings. Follow these steps to create your own monster masterpiece.
Ingredients
- 1 box (18.3 oz) brownie mix (plus eggs, oil, and water called for on the box)
- 1/2 cup creamy peanut butter
- 1/2 cup quick-cooking oats
- 1/2 cup candy-coated chocolate pieces (M&Ms)
- 1/4 cup semi-sweet chocolate chips
- 1/4 cup white chocolate chips
- 1 tablespoon candy eyes (optional, for a monster look)
Directions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Lightly grease a 12-inch round pizza pan or a large tart pan with non-stick cooking spray or a little bit of butter to ensure the brownie doesn’t stick.
Step 2: Mix the Batter
In a large mixing bowl, prepare the brownie mix according to the package instructions using the required eggs, oil, and water. Once combined, stir in the creamy peanut butter and the quick-cooking oats until the batter is smooth and well-incorporated.
Step 3: Spread the Dough
Pour the batter onto the prepared pizza pan. Use a spatula to spread it evenly toward the edges, leaving a small gap near the rim as it will expand slightly while baking.
Step 4: Add the Toppings
Sprinkle the candy-coated chocolate pieces, semi-sweet chocolate chips, and white chocolate chips evenly over the top of the brownie batter. Press them down very lightly so they stick but don’t sink completely.
Step 5: Bake the Pizza
Place the pan in the oven and bake for 20 to 25 minutes. You want the edges to be set, but the center should still be slightly soft. Avoid overbaking to keep that fudgy brownie texture.
Step 6: Cool and Decorate
Remove the pan from the oven and let it cool completely on a wire rack. If you are using candy eyes, press them into the top while the brownie is still slightly warm but not hot enough to melt them. Once fully cooled, slice into 12 wedges.
How to Serve Monster Brownie Pizza Recipe
Serve this brownie pizza on a large cake stand or a wooden pizza board for a fun presentation. You can serve it as is, or level it up by adding a scoop of vanilla ice cream on top of each slice. For an extra touch of decadence, drizzle a little bit of warm chocolate ganache or melted peanut butter over the entire pizza before slicing.
How to Store Monster Brownie Pizza Recipe
To keep your brownie pizza fresh, store any leftovers in an airtight container at room temperature for up to 4 days. If you prefer a firmer texture, you can keep it in the refrigerator for up to a week. You can also freeze individual slices by wrapping them tightly in plastic wrap and placing them in a freezer bag for up to 3 months.
Expert Tips for Perfect Monster Brownie Pizza Recipe
For the best results, do not overmix the batter once you add the flour and oats; mixing too much can make the brownie tough. Using a pizza stone is an option, but a metal pizza pan usually yields a better crust for brownies. If you find the peanut butter is too stiff to mix, microwave it for 15 seconds to soften it before adding it to the batter.

Delicious Variations
You can easily change the flavors of this pizza. Try using a blondie mix instead of a brownie mix for a “white chocolate” version. If you have a nut allergy, swap the peanut butter for sunflower seed butter or simply omit it and add extra oats. For a salty-sweet twist, sprinkle a handful of crushed pretzels on top before baking.
Frequently Asked Questions
Q: Can I use a homemade brownie recipe instead of a box mix?
Yes, you can use your favorite homemade fudgy brownie recipe. Just ensure the volume of batter is similar to a standard 18-ounce box mix.
Q: My brownie pizza is sticking to the pan. What should I do?
Make sure to grease the pan thoroughly next time. For now, try running a thin spatula or knife under the edges while it is still slightly warm to loosen it.
Q: Can I use old-fashioned rolled oats instead of quick oats?
Quick oats are preferred because they blend better into the batter. Rolled oats will be much chewier and may change the texture significantly.
Q: How do I know when the brownie pizza is done?
The edges will look firm and slightly papery, while the center should no longer jiggle. A toothpick inserted an inch from the edge should come out mostly clean.
Q: Can I make this in a rectangular sheet pan?
Certainly! It won’t look like a pizza, but it will taste just as good. Adjust the baking time as a rectangular pan might result in a thinner or thicker layer.
Conclusion
The Monster Brownie Pizza is a delightful and easy dessert that brings joy to any occasion. With its chewy edges, fudgy center, and colorful candy toppings, it is as fun to make as it is to eat. Whether you are baking for a party or just a sweet weekend treat, this recipe is sure to be a massive hit with everyone who tries a slice.
