What You’ll Need
You’ll see two sets of ingredients for this keto brownie recipe. A couple of them are repeats for the topping and the brownie themselves.
- Butter - You’ll need to use salted, melted butter to get the right texture and flavor.
- Water - The water needs to be warm, but not hot.
- Eggs - To properly combine the ingredients and bind them, it’s important to use room temperature eggs. You can set them on the counter 30 minutes - 1 hour before making the brownies. Or you can place them into a bowl of warm water to speed up the process.
- Sweetener - My sweetener is the best combination I have found for making these keto peanut butter brownies. I do have a few alternatives for you in the recipe notes if you want to try something else.
- Almond & Coconut Flours - Using a combination of these two gluten free flours gives the keto brownies a fantastic texture.
- Cocoa - To give them a rich and decadent taste, you will need some cocoa. Use unsweetened to ensure it is low carb.
- Vanilla - A little bit of vanilla extract brings out the rest of the flavors.
- Baking Powder - Using baking powder is a must, so the brownies raise enough while baking.
- Salt - Just a little bit of salt will help bring out the sweetness in the peanut butter brownies.
- Peanut Butter - Luscious creamy natural peanut butter is the star of these brownies.
- Cream Cheese - The cream cheese really elevates the flavor as well as the texture to make these the ultimate brownies.
- Butter - You’ll need a little bit more melted butter for the topping. Make sure you use salted butter for this too.
- Sweetener - A little bit more sweetener, and you will have the perfect topping!
How To Make Keto Peanut Butter Brownies
This is a pretty straightforward recipe, and it’s even great for the beginning baker! Don’t be afraid to tackle this easy dessert!
Step One: Grease a 9x9 baking dish and preheat the oven to 350 degrees F.
Step Two: Combine the melted butter, warm water, and eggs together in a large bowl. Slowly add the sweetener, flour, cocoa, vanilla, salt, and baking powder into the butter mixture.
Stir and pour into the baking dish.
Step Three: Prepare the topping by combining the peanut butter, cream cheese, butter, and sweetener together. It will be thick.
Using a spoon, drop dollops of the topping on top. The peanut butter layer is a bit too thick to swirl into the chocolate batter. If you really want to make these peanut butter swirl brownies thin it with a little warm water so you can make peanut butter swirls.
Expert Tip: I actually find it easiest to do this with 2 spoons. I scoop some filling the first spoon and push it off the spoon and onto the brownie batter with the second spoon.
Step Four: Bake the brownies for 35-40 minutes or until it’s puffed up and it’s jiggly in the center.
How Do You Cut Brownies
Cutting brownies can either be easy or an utter disaster! Over the years and with much practice, I have figured out exactly what to do to cut fudgy keto brownies with ease and look beautiful. This is especially helpful if you are taking them to friends or family!
- Don’t cut the chocolate peanut butter brownies while they are still hot. This will cause little clumps to stick to the knife, and as you make cuts, more will keep sticking. They are the easiest to cut after chilling in the refrigerator.
- Using a plastic knife is very helpful. I know it seems strange, but brownie bits don’t stick to plastic the same what it does to a regular knife.
- Add a little grease or non-stick spray to the knife, so nothing sticks to it. No need to go overboard; a little bit will do the job.
- If you do want to use a steel bladed knife instead of plastic, heat it up by dipping it into hot water. Dry it before cutting, but the warmth helps make the slices smooth.
How Do You Store Keto Peanut Butter Brownies?
Keep the brownies in an airtight container once they have cooled. They will last 3-4 days at room temperature or up to 2 weeks in the fridge. In general, I keep all the baked good from my low carb recipes in the fridge. And, I like these best after they have been chilled.
Substitutions, Add-Ins, & Serving Ideas
Sugar Free Chocolate Chips - if you are someone who can never have too much chocolate go ahead and sprinkle in a handful before popping these in the oven.
Sunflower Seed Flour - this can be subbed for the almond flour if you cannot have almonds. You can also sub sunflower seed butter for the peanut butter to make these entirely nut-free.
Sea Salt - if you choose a peanut butter that is unsalted I highly recommend sprinkling a pinch of sea salt over the top of these after baking. The sweet-salty combination in these peanut butter chocolate brownies is fabulous.
Ice Cream - who can resist a warm brownie with a scoop of keto vanilla ice cream? I know I can't!
- 1 cup peanut butter
- 2 oz cream cheese
- 2 tablespoon salted butter melted
- ¼ cup Joy Filled Eats Sweetener (or see alternatives in recipe notes)
- Preheat oven to 350. Grease a 9 x 9 baking dish.
- In a large bowl whisk together the butter, warm water, and eggs. Add the dry ingredients and mix well. Pour into the baking dish.
- In a small bowl stir together the topping ingredients. Drop dollops on top of the batter.
- Bake for 35-40 minutes or until the entire brownie has puffed up and is no longer jiggly in the center.
