I don’t mean to brag, but these gluten-free flourless peanut butter brownies might just be the best thing to come out of my oven all month.
They’re dense like fudge. Chewy on the edges. Soft in the middle. Rich, peanut buttery, and totally flourless — not a speck of gluten in sight. You only need a handful of real, fresh pantry staples. And guess what? You won’t miss the flour. Not even a little.
I’ve baked these for bake sales, parties, mid-week blues, and once — not kidding — because someone double parked me in. I had 45 minutes to kill and peanut butter in the cabinet. The rest is delicious history.
Now I’m sharing the whole thing with you, step by fudgy step.
Why You’ll Want to Make These on Repeat
Zero flour. 100% craveable.
These aren’t pretending to be brownies. They are brownies. Just without flour. You don’t need to “settle” for gluten-free here — these are legit good.7 simple ingredients.
You can pronounce all of them. You probably already have most of them in your kitchen. And nothing’s weird or hard to find.One bowl. No mixer.
No fancy equipment. Just a bowl, a spoon, and enough self-control not to eat the batter raw (though I won’t blame you if you do).That texture though.
Soft centers, crackly tops, gooey edges — basically everything a brownie should be.
What Makes These Work (Even Without Flour)
This is where the food nerd in me comes out. Flour usually gives brownies structure, right? But peanut butter steps in like a boss and handles that job without breaking a sweat. Add eggs (binding + richness), sugar (moisture + texture), and cocoa (structure + depth), and boom — you’ve got fudgy magic. No flour needed.
The result? Dense, chewy, ultra-moist brownies that don’t feel like a substitute. They just feel…right.
What to Serve Them With (or Not)
These don’t need anything, but if you’re feelin’ fancy:
A scoop of vanilla ice cream — enough said.
A drizzle of warm peanut butter on top (or Nutella if you’re feeling rebellious).
Cold milk, because old school is sometimes the best school.
How to Store (If There’s Any Left)
Wrap them up tight in foil or pop them in an airtight container:
Room temp: 3–4 days, no problem.
Fridge: up to a week (but the texture gets firmer).
Freezer: wrap slices individually and freeze for up to 2 months. Warm in the microwave for 20 seconds for a fresh-baked feel.
Real Talk: Ingredient Swaps That Work (and What Doesn’t)
I get it — you might not always have exactly what’s listed. So here’s what you can get away with:
Almond butter instead of peanut butter: Totally works. It’ll taste more mellow but still amazing.
Coconut sugar instead of brown sugar: Will be a little less chewy, but the flavor still rocks.
No chocolate chips? Leave them out or swirl in a spoonful of raspberry jam before baking. That sweet-tart combo is gold.
What doesn’t work?
Don’t use peanut butter that’s full of oil and sugar. Your brownies will bake weird and greasy. Stick with natural.
Don’t sub flax eggs. I’ve tested it. They fall apart. Use real eggs for structure.
Little Extras That Take These Up a Notch
Want to show off? Try one of these before baking:
Sprinkle flaky sea salt on top.
Add a swirl of natural peanut butter on the surface for that marbled effect.
Throw in some roasted chopped peanuts for crunch.
Drop in a few chunks of caramel and let them melt into the batter.
The Origin Story (Why I Made These in the First Place)
So here’s the thing — I’m not someone who “accidentally” ends up baking brownies at 10pm. I plan that stuff. But this recipe? It was a last-minute save.
I had promised dessert for a dinner party and realized I was out of flour. Like, none. I had eggs, peanut butter, sugar, and some cocoa powder. I shrugged and tried to wing it. And what came out of the oven was so ridiculously good, nobody believed it was gluten-free. Not even the guy who always brings his own stash of “real” brownies.
Since then, this has been my emergency, party, midnight-craving, please-the-picky-crowd go-to recipe. It just works — every time.

Flourless Peanut Butter Brownies (Gluten-Free & Ridiculously Good)
- Total Time: 32 minutes
- Yield: 16 small squares or 9 large brownies
- Diet: Gluten Free
Description
These fudgy, chewy peanut butter brownies are totally flourless and naturally gluten-free. Just one bowl, real ingredients, and ready in under 30 minutes. The crackly tops and gooey centers make them a total crowd favorite.
Ingredients
1 cup creamy natural peanut butter
(The kind with just peanuts + salt. No sugar. No junk.)2/3 cup light brown sugar
(Tightly packed. Adds richness and that caramel edge.)2 large eggs
(Room temp if possible. Fresh from the farmstand is always best.)1/4 cup unsweetened cocoa powder
(Look for Dutch-processed for deeper flavor, but natural works too.)1 tsp baking soda
(Gives them just enough rise.)1 tsp pure vanilla extract
(Use the good stuff. You’ll taste it.)1/2 tsp sea salt
(Balances the sweet. Makes chocolate sing.)
Optional but amazing:
1/2 cup chopped dark chocolate or chocolate chips
(I go with 70% cacao, chopped roughly. Ghirardelli or local chocolate shops are great picks.)
Instructions
1. Preheat that oven.
Set it to 350°F (175°C). Line an 8×8-inch metal baking pan with parchment paper, letting it hang over the sides for easy lifting later.2. Mix it up.
In a large bowl, stir the peanut butter and brown sugar until smooth and glossy. Add the eggs, one at a time, mixing well after each. Stir in the vanilla.3. Add the dry stuff.
Sprinkle in the cocoa powder, baking soda, and salt. Stir until combined — don’t overmix. Fold in the chocolate chunks if using.4. Bake time.
Pour the batter into your prepared pan. It’ll be thick — that’s what you want. Smooth the top with a spatula.Bake for 20–24 minutes, or until the center looks just set and the top has that crackly brownie finish. Don’t overbake.
5. The hard part: wait.
Let the brownies cool completely in the pan before slicing. Trust me. They firm up as they cool and the texture gets perfect.
Notes
Use natural peanut butter (just peanuts + salt) for best results. Avoid processed peanut butter with added sugar or oils. Let brownies cool fully before slicing to help them firm up. Store airtight for up to 4 days, or freeze individually for a quick treat later. Add a sprinkle of flaky salt before baking for a bakery-style upgrade.
