I don’t know what happened but that glaze was awful! I threw it out and redid it 3 times. I even opened a new bag of powdered sugar thinking maybe it had gone bad. Nope. It had a weird artificial metallic taste. I thought maybe it was because it was by itself and that taste would disappear once poured onto the cake. Double nope. It completely overpowered the cake. It was like a bite of artificial metallic mud. I will attempt the cake again but try a root beer buttercream icing instead.

Great to make with Grandkids! Double the glaze for sure!
Donna Farmer
I made this per the instructions and it’s not as strong a flavor as I expected. It’s very moist and a good cake but I was anticipating a much stronger taste.
Tanya Smith
Zero root beer flavor. Will not make again.

combined 2 recipes. only used two eggs. after reading many reviews I added 1.5 tablespoons root beer extract to cake batter. After baking cake for 30 min. took out promptly, when thoroughly cooled I flipped cake over and put back in 9 x13. After poking holes in cake with toothpick I poured glaze on top. Glaze recipe was 9 tablespoons of root beer soda, 1 T RB extract and 1.5 cups powdered sugar. Finally, On top of all I added freshly whipped cream with RB soda and powdered sugar mixed in (to taste) spread over all cake and refrigerated overnight. wow.

It was a hit! The glaze soaked into the cake and made really moist.
Denise Davis
I didn’t use the glaze but the cake was so moist and delicious.

I didn’t use the glaze but the cake was so moist and delicious.

This is a moist and not-too-sweet cake, perfect for after a meal of rich foods. I did make more of the glaze as others suggested but really didn’t taste the root beer flavor, but my guests all said it was good. I looked for root beer extract and didn’t find any readily available so I made this according to recipe. It was “ok”, not a show-stopper but I will keep it in my recipe box. Thanks for sharing, Karin!

This is just yummy. I served it as coffee cake on a recent trail ride. Good reviews by all. So easy to make. Another review said they had trouble finding an 18.25 oz mix. I just used whatever size I had on hand and replaced the water with root beer and it worked fine.
Timothy Perez
Was very tasty. I did add a box of vanilla pudding mix to keep it extra moist. The root beer flavor was more subtle than I had thought it would be. I will try a craft root beer next time to see if that helps make the root beer more prominent.
Paul Rodriguez
Really good. I used 2 tsp rootbeer concentrate in the cake and 1 tsp in the glaze. I thought the amount of glaze was perfect.
Charles Cross
This cake is moist and delicious if adjustments are made. After reading previous reviews, I made the following changes/additions: 1. I added 1 tsp. root beer flavoring/extract to both the batter and the glaze; 2. I doubled the glaze mixture and increased the confectioner’s sugar amount so it would be a bit thicker; 3. After the cake was completely cooled, I poured half of the glaze into the bundt pan then place the cake back in the pan after poking holes in the top with a wooden skewer; I pressed and swirled it so the cake would absorb the glaze; I then let it set in the bundt pan for 15 min., after which time, I flipped the imbibed cake onto a rack and spooned the rest of the glaze over the top. I let the glaze drip/dry completely then dusted it with confectioner’s sugar before cutting. Great root beer flavor without being overpowering. I will make this again and be sure to have vanilla ice cream on hand to go with it.

I was looking forward to eating delicious Rootbeer cake. I added concentrate, doubled the glaze and let the cake soak in glaze in the pan as others have advised. But the cake was heavy and tasteless. Later I discovered my error. A standard cake mix at my grocery store is 14 ounces. The recipe calls for an 18.25 ounce mix. Amazon carries this size. (The star rating only reflects my experience. The recipe may be excellent.)

This cake is awesome, I am not a big root beer fan, but my family is so I thought what a treat. And it was delicious. I added a little extra powdered sugar to the 3 TBSP of root beer so that the glaze was a little more thick…I made it as directed without the root beer extract (gosh hard to find). I added just a little more oil since bundt cakes can be heavy and dry. I use Joy Bakers spray and my cakes never, ever stick! This is such a treat of a cake!!! Thank you and keep the recipes coming!!!
Mary Butler
taste very much like root beer. Added the additional rootbeer flavoring and it was a hit! Super moist and rises well in bundt pan…..I didn’t experience any falling which often happens with soda pop cakes
Aaron King
This turned out great for me. Was looking for a way to use up some old root beer and this caught my eye because it was so easy. My family couldn’t guess it was root beer, so if you are looking for a real strong root beer favor look elsewhere. But, everyone did like it.
Amanda Williams
Excellent as written, I doubled the glaze and used 1/2 on top and 1/2 on bottom and it was still excellent…..scrumptious with vanilla ice cream.
Steven Atkinson
Very easy to make, moist and flavorful. I have made it several times.
Christopher Chavez
taste was good-texture was marginal.
Willie Lane
I used a yellow sugar free cake mix, and diet dr. pepper for this recipe… everyone loved it and was was perfect for me as I can’t have sugar! No one even knew it was sugar free and raved about it…
