The Effects Of Adding Too Much Baking Powder


What is baking soda? What does it do in baking? Does too much baking powder affect my food? Should you replace your old boxes of baking powder with new ones-or are they interchangeable if done correctly, and why would you want to use one over the other for a particular recipe?

To answer all these questions, please read on. I shared with you a recipe for marmalade pudding cakes pulled from my family’s recipe box.

The original had plenty of baking soda, which made them brown significantly as they cooked; like any good chemist who blames their darling ingredient when things go wrong (isn’t that the scientific way?), I wanted to investigate what was going on! before knowing why too much baking powder can have detrimental effects on your food it is vital to what is baking powder.

What Is Baking Soda?

Baking soda is the common name for a chemical called sodium bicarbonate, or as the Brits call it, “bicarbonate of soda.” This chemical formula is NaHCO3. Sodium bicarbonate is basic (as in alkaline- pH level > 7), and reacts under acidic conditions to produce carbon dioxide gas that helps your baking rise (water and salt are also produced).

Baking soda is a chemical leavener, unlike yeast. Yeast is an organism that feeds on sugar and produces CO2 through fermentation: the yeast eats sugar, digests it then produces CO2 with other compounds like alcohol.

Your bread rises because of the yeasts that eat sugars from the dough and produce gas while cakes rise because too much baking powder reacts to acids producing gas too. This principle also applies to too much baking powder- another agent in leavening foods.

When you add more or less of these agents into the batter it will affect how they cook together giving different tastes/textures as well as colors (like when discussing Maillard reactions).

As you bake a loaf of bread or cake, the color changes from golden to brown. The sweet flavor transforms into something much deeper and not as sweet. French pastry chefs like to call it “golden brown delicious” and this change in taste occurs because of the Maillard reaction: sugars break down/transform into dark-colored polymers which contribute to the aroma and flavor of baked goods.

What Happened If You Add Too Much Baking Soda?

It’s important to use the right methods when measuring your ingredients. If you don’t, it can be easy to over or under-measure baking soda!

Adding too much Baking Soda May Cause a Bad Taste

This meant that the resultant cake batter had a higher pH, and thus there was more Maillard reaction happening- hence more browning occurred while steaming for an hour. More baking soda = more browning!

However, with too much baking soda reacting in such cases, some will remain unreacted even though excess amounts are left behind – meaning that flavors could be adversely affected if they taste soapy or sharp after too much exposure to said excess.

Too Much Of It Can Affect The Shape

I observed the original pudding cakes had a very tender crumb, and they were spongy and soft. On the other hand, with one-eighth of the baking soda in them, puddings became much firmer but not as fluffy.

Once again we can blame baking soda for providing lots of rising power to these pudding cakes but actually, I noticed that when there was less baking powder in them they domed more while those containing greater amounts have become flatter yet retaining bubbles at their sides and base. Too much baking powder.

Thumb Rule To Use Baking Soda

Too many, too much baking soda is not a good thing. It might create bubbles in cakes that end up making them sink and giving the cake an odd flavor. So do you need too much baking powder? The basic rule for adding enough to a recipe is ¼ teaspoon of it per cup of all-purpose flour (125 grams).

Recipes that contain large volumes of acidic ingredients require ½ teaspoon of baking soda to neutralize 1 cup of mild acid. For example, this Irish soda bread with raisins is made with 500 mL (2 cups) sour cream and 1 teaspoon too much baking powder.

Of course, these are just a guideline and recipes may vary for other reasons (pan size, presence or absence of “heavy” ingredients like nuts and dried fruit which might require extra leavening).

Does Baking Soda Expire?

Baking powder will eventually expire and lose its potency due to both baking soda and acid that it can react within the presence of humidity. For this reason, it is super important to check on your baking powder periodically. Too much baking powder.

However, baking soda does not expire because all you need is sodium bicarbonate, a single compound that doesn’t break down when exposed to some humidity from the air like when mixed with other ingredients or baked as part of the batter.

Issues with Old Container

It’s not that the baking soda will break down over time and stop working but rather, it will clump. You’ll have trouble incorporating your clumpy mixture into cake batters and other baked goods which can then lead to scattered spots of cooking powder in the cakes or cookie doughs.

These clusters will lead to tiny patches of cooking powder in your foods so brown spots occur as well as larger air pockets within them; making them less appetizing than they could’ve been otherwise. too much baking powder

How To Store Baking Soda?

Baking soda is a sensitive ingredient because it will lose clumps if exposed to moisture. The best way to avoid this problem is by storing the box of baking soda inside another bag that has seals or transferring it into an old Ziploc container before opening (or even just storing all of your potentially problematic substances inside containers).


Baking soda is an important leavening agent in baking. We all use it and it does a lot more than just cause cakes to rise!

Baking soda is alkaline, so adding it to recipes also affects the color, flavor, and texture of baked goods-which may be too much like commercial or homemade baking powder.

I hope this guide has helped you enough to know the drawbacks of adding too much baking powder to any food as adding too much baking powder can have many detrimental effects on your body.
