    Lemon brownies made with cake mix stacked

    This lemon cake mix brownies recipe is made with a cake mix, and only a handful of other ingredients, creating an easy, gooey brownie dessert that lemon lovers adore!

    Quick Overview: Only 6 ingredients, and a prep time in as little as 5 minutes, you’ll have lemon brownies baked in 20 minutes + optional glaze recipe!

    Lemon is delicious any time of year but especially in the summer months! And with this summery dessert, you won’t be standing in front of a hot stove and it only has to be in the oven for 18-20 minutes!

    A Dense, Ooey Gooey Brownie

    If you’re looking for a cake-style brownie, this won’t be it! This brownie recipe has an ooey-gooey texture and is very dense and rich!

    With a cake recipe, using a cake mix, most call for water, giving it more of an airy, cakey, texture. This recipe does not use water so it creates a thick, brownie batter.

    If you prefer more of a cake-style, adding a little water may be for you but just keep in mind that it may change the bake time, and it may result in just making a lemon cake, instead of a lemon “brownie”.

    This was inspired by the strawberry brownies that have gone viral on Facebook and being a lemon lover myself, I knew a lemon version of the brownies would be a HIT as well!

    Lemon Brownie Ingredients

    The first part of this recipe is for the brownie batter! All you need is:

    • lemon cake mix
    • vegetable oil
    • eggs
    • vanilla extract
    Lemon brownies ingredients

    Lemon Glaze Ingredients

    The second part of this recipe is for the optional (but highly recommended) lemon glaze! Here’s all you need for the glaze:

    • powdered sugar
    • fresh lemon juice
    • (milk is optional, to help thin it out if needed)
    Lemon Glaze Ingredients

    See the full, printable recipe card at the bottom of this post to get measurements and instructions!

    Instructions

    1. Spray non-stick cooking spray on an 8×8 baking dish.

    Gather all of your ingredients and a medium-sized mixing bowl.

    1. Pour the cake mix in to your mixing bowl.

    1. Next, add in the vegetable oil
    Add eggs in to cake mix
    1. Then the two eggs
    Pour vanilla in to cake mix
    1. Finally, the vanilla extract
    Mix cake mix with oil, eggs and vanilla
    1. Mix ingredients together until evenly combined. You should have a thick batter like shown in the image below.

    1. Press brownie batter in to baking dish, in an even layer, making sure the batter touches the sides.

    1. Place baking dish in preheated oven and set timer for 18 minutes.
    Mix together the lemon juice and powdered sugar
    1. While lemon brownies are baking, mix up the lemon glaze if desired. Mix together the powdered sugar and lemon juice and stir until evenly comined, creating a consistency similar to the image below.
      If glaze is too thick (you didn’t have enough lemon juice, you can add a teaspoon of milk until it reaches the consistency desired.)

    1. Once brownies are finished baking, (they’re finished when you stick a toothpick in to the center and it comes out clean) remove from the oven and place baking dish on a cooling rack so the brownies can begin to cool.

    1. Once the brownies have cooled (or at least have cooled off enough to where the brownies are just a tad warm still) pour glaze over the top and spread evenly over the brownies.

    1. Allow glaze to harden (it can sit out at room temperature), which should only take about 10 minutes or so.

    1. Once the glaze has hardened, it’s safe to cut the brownies and to serve! They’re delicious a LITTLE warm (they need to be cooled off enough so the glaze hardens) but are also delicious room temperature as well.

    What to Serve with Lemon Brownies

    The lemon brownies are very rich and can be enjoyed alone but they’re also incredible, topped with a scoop of vanilla ice cream, or even sliced sugared strawberries.

    How to Store Brownies

    Once the brownies have cooled completely, store any leftovers in an airtight container, on the counter for 3-4 days. They do not have to be refrigerated, although refrigerating can extend the life of the brownie, to at least a week.

    Helpful Tips:

    • If you prefer more of a cake icing for your brownies, you can use canned frosting instead of the lemon glaze.
    • If you prefer a citrus variety, you can zest limes or oranges and incorporate the zest/juices instead of only lemon.

    • 1/3 cup vegetable oil
    • 2 eggs

    Instructions
     

    For Brownies

    • Preheat oven to 350 degrees and grease 8×8 baking dish with cooking spray
    • In a medium sized mixing bowl, mix together the cake mix, eggs, oil and vanilla until evenly combined.
    • Press brownie batter (it will be thick) in to the bottom of the baking dish, pressing it to an evenly layer, making sure it's pressed all the way to the sides.
    • Bake at 350 degrees for 18-20 minutes or until a toothpick is inserted in the middle of the brownies and comes out clean.

    Lemon Glaze

    • While baking, mix together lemon glaze if desired. In a small bowl, mix together powdered sugar and juices from lemon (about 2 tbsp). If glaze is not thin enough to pour, you can add milk by the teaspoon until it has reached the desired consistency. (You do not want it too thin or it will not harden.)
    • Remove brownies from oven and place baking dish on cooling rack so it can begin to cool.
    • Once brownies have cooled, pour the lemon glaze on top of the brownies, spreading with a spoon so that it evenly covers the brownies.
    • Let the brownies sit to allow the glaze to harden and cut brownies in to 9 equal squares (unless you prefer smaller) and serve!

    Notes

    Helpful Tips:

    • If you prefer more of a cake icing for your brownies, you can use canned frosting instead of the lemon glaze.
    • If you prefer a citrus variety, you can zest limes or oranges and incorporate the zest/juices instead of only lemon.

      This tastes awesome! Only thing is, It was very crumbly and fell into pieces when I pulled it off the pan. Tastes good. Made it for mothers day
