Ingredients and substitutions for peanut butter muffins

Peanut Butter. I use natural peanut butter and since they are peanut butter muffins after all, I highly suggest you use your favorite peanut butter! But, if you absolutely have to, yes you can use another nut or seed butter.

Agave Nectar. I use this to sweeten up the muffins, but you can use honey or maple syrup if you prefer!

Eggs. Just two! I haven’t tested this with vegan eggs or flax eggs, so if you do any experimenting, let me know how it goes!!

Vanilla Extract. For some warm, vanilla, baked good flavors.

Almond Four. This is going to give the muffins some structure and fluff!

Baking Powder. We need this to give the muffins some lift and fluff. Both peanut butter and almond flour can be heavy and dense, so the baking powder if going to help counteract that.

Salt. Brings out the peanut butter flavor! But! Look at your peanut butter jar. If you are using salted peanut butter (I don’t recommend) then I’d leave the salt out. You don’t want these muffins to be too salty! But if you’re using unsalted peanut butter, you can add some to the batter.

Peanut Butter Chips. Mmm what is it about peanut butter chips that are just sooo good? I am pretty generous topping these muffins with peanut butter chips and definitely recommend snacking on a few while you bake 🙂 I love using peanut butter chips, but if you want to switch it up, try some semi-sweet or white chocolate chips!

Can I substitute oat flour for almond flour?

Yes! Oat flour is great because it makes baked goods super fluffy and delish! If you’re using oat flour I would reduce the amount by half. In this recipe we’re using 1 cup of almond flour so I would use 1/2 cup of oat flour.

Natural peanut butter vs. regular peanut butter

Natural peanut butter usually means there is only peanuts in the peanut butter. Some have salt added but natural peanut butter just has one main ingredient – peanuts! “Regular” peanut butter can have oil, sugar, and other ingredients mixed in.

I love both kinds of peanut butter for different reasons. I tend to stick with natural peanut butter for baking to make sure the extra add-ins don’t effect the consistency or flavor of the baked goods.

Best natural peanut butter

There are so many good options for natural peanut butter. Crazy Richard’s peanut butter and Spread the Love peanut butter are two great brands that I love!

How to make peanut butter muffins

Wet ingredients. Whisk together the peanut butter, agave, eggs, and vanilla. Don’t over-mix, but whisk until combined.

Dry ingredients. Add the almond flour, baking powder and salt to the bowl. Mix again until combined. Then, fold in most of the peanut butter chips, saving some to sprinkle on top.

Scoop. Use an ice cream scooper to scoop the batter into lined muffin tins. You want to fill the muffin tins about 1/2 to 3/4 full.

Top. Add those peanut butter chips on top of the muffins.

Bake. Pop them in the oven for 15 minutes and then allow to cool for a few minutes.

Enjoy! Transfer to a cooling rack and enjoy!

How to store and freeze these muffins

Once cooled, you can store the muffins in an airtight container on the counter at room temperature for about three days.

You can store them in an airtight container in the fridge for about a week or wrap them in plastic wrap and foil and freeze them for three months.

To defrost, allow the muffins to come to room temperature and warm in the microwave or oven to heat through.
