Flourless Almond Butter Brownies

These flourless almond butter brownies are so fudgy and rich, you’d never know they’re completely gluten-free, dairy-free, and contain no flour or oil at all. This one bowl recipe requires no mixer and uses creamy almond butter in place of dairy butter for added protein, fiber, and depth of flavor. Make it in an 8×8″ square pan or an oven-safe skillet!

Why you’ll love this recipe

You know those super long days (usually, a Monday, but I’m not trying to be prejudiced against Mondays here – it can happen any day) when you get home, plop down on your couch, and you know that only dense, rich chocolate is going to make things ok? (Also, wine.) I created this recipe with those days in mind.

This almond butter brownie recipe is:

• SUPER EASY to make. We’re talking one bowl, no mixer, stir it all together type of situation. You can even mix AND bake it in the same oven-safe skillet if you like (but not necessary if you don’t).
• Quick – the whole recipe takes 40 minutes start to finish.
• Simple – 10 ingredients, a couple of which are optional!
• Decadently chocolatey – almond butter makes these brownies super fudgy and rich, and provides enough protein to eliminate the need for flour to hold everything together.
• Flourless brownies! Excellent. Gooey brownies, here we come.
• Food allergy friendly – I give substitution options below if you have a nut allergy or need to make the recipe egg-free.

Ingredients

See the recipe card at the bottom of the post for measurements! Simple and mostly wholesome ingredients here:

• One cup of almond butter. Creamy natural almond butter is best (just almonds and salt). I like Trader Joe’s brand, but homemade almond butter will work perfectly. You can substitute peanut butter, cashew butter, or hazelnut butter. If you have a nut allergy, use sunflower seed butter or tahini in its place.
• Granulated sugar
• Eggs. For an egg-free option, flax eggs would work here (2 tbsp flax + 5 tbsp water).
• Unsweetened cocoa powder (natural or Dutch process will both work)
• Milk (dairy or non-dairy milk both work)
• Vanilla extract
• Baking soda
• Salt
• Espresso powder (optional, for deeper chocolate flavor)
• Chocolate chips or chopped dark chocolate (optional)

How to make flourless almond butter brownies: step by step

The great thing about this recipe is you can make and bake it all in one oven-safe skillet, if you like (I used a 12-inch cast iron skillet). If you don’t have one, just mix the batter in a bowl and spread into an 8×8 inch square pan.

Step 1: Stir together almond butter (I find room temperature almond butter is best – use a fresh jar), milk of choice, and sugar in a large bowl or a 12-inch oven-safe skillet until fully combined.

Step 2: stir in the eggs, one at a time (the batter is a little stiff at first so be careful and gentle when stirring). Make sure each egg is fully incorporated before continuing. Stir in the vanilla extract as well.

Step 3: add the dry ingredients: cocoa powder, espresso powder, baking soda and salt, and stir together until a brownie batter forms.

Step 4: Fold in dark chocolate chunks. Spread brownie batter in a parchment paper lined 8×8 baking dish or in a 12-inch oven-safe skillet. Sprinkle some more chocolate chips on top of the brownies before baking because, why not?

Step 5: Bake 25-30 minutes. The top should be shiny and beautiful when it’s done and a toothpick should come out mostly clean. For super fudgy gooey brownies I recommend staying on the shorter end of the range, but I like the airy texture of these when fully baked so I go closer to 30 minutes.

Step 6: Now comes the best part. Put a scoop of vanilla ice cream on a warm chocolatey brownie, or dump ice cream right over top of the warm skillet brownie and dig in. No plates, no bowls. Just spoons.

Additions and Substitutions

• Almond butter: use any nut butter or seed butter in its place.
• Sugar: brown sugar or coconut sugar will work. I’ve also used up to 1/4 cup maple syrup in place of 1/4 cup sugar with good results.
• Make it egg-free or vegan: use 2 flax eggs (2 tbsp ground flax + 5 tablespoons water) and make sure to use vegan chocolate chips.

Storage

If you do happen to have leftovers of these grain-free almond butter brownies, you can store them:

• At room temperature for up to 3 days in an airtight container.
