Gem cake is a soft butter cake made with all-purpose flour, baking powder, butter, sugar, eggs, milk, sour cream, vanilla, and colorful chocolate gems, baked in a 9-inch round pan in about 60 minutes total. This Pastel con Gemas yields 8 servings and gives you a tender crumb with playful candy pieces in every slice.
I am Hana, a home baker and the founder of EmpireFoodie.com, and I tested this Pastel con Gemas for a simple cake that stays soft without feeling heavy. Theo noticed the candy pieces first, and that told me the texture balance was right.
The crumb is tender because the butter and sugar are beaten until light, then the milk and sour cream add moisture without thinning the batter too much. The chocolate gems bring little pockets of sweetness, so every slice of Pastel con Gemas feels lively but still balanced.
I also like that this cake uses one 9-inch pan and a short ingredient list, which makes it practical for birthdays or an easy homemade dessert. The full bake time is 35 to 40 minutes, so the final result is achievable on a busy day.

Why does this Gem Cake work so well?
Gem Cake works so well because Pastel con Gemas combines a simple butter cake base with coated chocolate gems, which helps the candy stay suspended in the batter instead of sinking. The result is an 8-serving cake with a soft crumb, even sweetness, and a playful texture in every slice.
- It stays tender. The combination of 1/2 cup unsalted butter, 1/2 cup whole milk, and 1/4 cup sour cream builds moisture without making the cake dense. That balance gives Pastel con Gemas a fine, soft crumb that slices cleanly.
- It bakes evenly. The batter goes into a 9-inch round cake pan, which helps the center cook through in the 35 to 40 minute window. That size also gives a neat shape for serving at celebrations.
- It looks festive without extra work. The mixed chocolate gems bring color and texture without requiring frosting or decorations. That makes Pastel con Gemas a smart choice when you want a special cake with minimal steps.
- It is reliable for home bakers. The method uses standard mixing and one pan, so the process stays approachable. I tested it with Theo nearby, and the candy pieces stayed evenly distributed after folding.
The butter-and-sugar creaming step matters because it traps air, which helps the cake rise more evenly. When the batter is mixed just until combined, Pastel con Gemas stays soft instead of turning tough.
What ingredients do you need for Pastel con Gemas?
Pastel con Gemas uses basic pantry ingredients, plus mixed chocolate gems for color and crunch. The recipe depends on 2 cups of flour, 3 large eggs, and a milk-sour cream mixture to keep the cake soft, while 1 tablespoon of flour coats the gems so they stay evenly spread.
- 2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 3 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup whole milk
- 1/4 cup sour cream
- 1 cup mixed chocolate gems or candy-coated chocolate pieces
- 1 tablespoon all-purpose flour, for coating the gems
- Butter or cooking spray, for greasing the pan
The butter should be softened, not melted, because softened butter creams with sugar and creates a lighter structure. The sour cream is also important in Pastel con Gemas because it adds richness and helps the crumb stay tender after baking.
How do you make Pastel con Gemas step by step?
The method for Pastel con Gemas is straightforward: prepare a 9-inch pan, mix the dry ingredients, cream the butter and sugar, then alternate the wet and dry ingredients before folding in the coated gems. The cake bakes at 350°F for 35 to 40 minutes and should cool in the pan for 10 minutes before finishing on a wire rack.
Step 1 — Prepare the pan and oven
Preheat the oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper so the Pastel con Gemas releases cleanly after baking.
Step 2 — Mix the dry base
In a medium bowl, whisk together the flour, baking powder, and salt. This even distribution helps the cake rise consistently and keeps the salt from clumping in one bite.
Step 3 — Cream the butter and sugar
In a large bowl, beat the butter and sugar together until light and fluffy, about 3 to 4 minutes. This step builds air into the batter, which gives Pastel con Gemas a softer texture.
Step 4 — Add the eggs and vanilla
Add the eggs one at a time, beating well after each addition, then mix in the vanilla extract. The eggs should blend smoothly into the butter mixture so the batter stays stable and glossy.
Step 5 — Combine the milk and sour cream
In a small bowl, combine the milk and sour cream. This mixture adds moisture and a slight tang that keeps the finished cake from tasting flat.
Step 6 — Finish the batter and fold in the gems
Add the dry ingredients to the butter mixture in three additions, alternating with the milk mixture, beginning and ending with the dry ingredients. Mix just until combined, toss the chocolate gems with 1 tablespoon of flour, then gently fold them into the batter so they are less likely to sink.
Step 7 — Bake, cool, and serve
Pour the batter into the prepared pan and smooth the top. Bake for 35 to 40 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs, then cool in the pan for 10 minutes before turning it out to cool completely.
Frequently Asked Questions About Pastel con Gemas
Why do the chocolate gems get coated in flour?
Coating the gems with 1 tablespoon of flour helps keep them suspended in the batter. This reduces sinking and gives Pastel con Gemas more even candy distribution in each slice.
Can I use softened butter instead of melted butter?
Yes, softened butter is the correct choice here. It creams with sugar for 3 to 4 minutes, which adds air and helps the cake rise with a lighter crumb.
How do I know when the cake is done?
Check it at 35 minutes with a toothpick inserted into the center. It is ready when the toothpick comes out clean or with a few moist crumbs.
Can I make Pastel con Gemas ahead of time?
Yes, you can bake it ahead and cool it completely before slicing. The cake keeps its soft texture well because of the butter, milk, and sour cream in the batter.
What pan size works best for this recipe?
A 9-inch round cake pan works best for Pastel con Gemas. It matches the batter amount and supports the stated bake time of 35 to 40 minutes.
What expert tips help this cake turn out right?
A few small habits make Pastel con Gemas more dependable, especially for busy home bakers. The goal is even mixing, steady baking, and a soft crumb that still holds the gems well.
- Use softened butter at room temperature. Soft butter creams properly with sugar, while cold butter will not trap enough air. That difference affects the final height and tenderness.
- Alternate the dry and wet ingredients. Adding them in three additions keeps the batter smoother and reduces overmixing. Less mixing means a more tender cake.
- Fold the gems in gently. Heavy stirring can break the batter’s structure and push the pieces downward. Gentle folding keeps the candy pieces visible and evenly spread.
- Let the cake cool for 10 minutes in the pan. That short rest helps the cake set so it does not break apart when turned out. Then the wire rack finishes cooling it evenly.
I use the 10-minute rest every time because it gives me a cleaner release from the pan. It also makes Pastel con Gemas easier to slice once it has fully cooled.
How should you serve Pastel con Gemas?
Pastel con Gemas serves nicely at room temperature after it has cooled completely. The 8 servings cut cleanly from a 9-inch cake, and the colorful pieces make each slice look special without extra decoration.
- Serve it plain. The cake already has butter, vanilla, and chocolate gem sweetness, so it holds its own on the plate. This keeps the crumb front and center.
- Pair it with coffee or tea. A simple drink balances the sweet candy pieces and highlights the vanilla base. This works especially well for afternoon serving.
- Slice it for celebrations. The round shape and bright candy pieces make Pastel con Gemas easy to portion for birthdays or casual gatherings. The clean slices help it look neat on a dessert table.
- Pack leftovers for later. Once cooled, individual slices hold well and make an easy treat for the next day. The texture stays soft because the batter includes milk and sour cream.
For me, the best serving style is the simplest one because it lets the texture speak for itself. Pastel con Gemas is at its nicest when the crumb is fully cooled and the candy pieces are still bright inside each slice.
